Light Catcher for IDFA

Our Light Catcher was especially designed for the immense foyer of this monumental building where IDFA is now settled. This new location at Vondelpark 3 in Amsterdam is accessible for the public.

The light object is made from lab-grown native algae and seaweed, which have been processed into a material that the Designers of the Unusual developed, called Wierwaar, which is used to 3D print the work.

The Light Catcher consists of modular elements that represent algae cells and give the feeling of an undersea kelp forest. It combines different types of micro and macro algae, which reflect light differently, leading to a range of colors and light reflections that continuously changes over the day, depending on the incoming light in combination with dynamic lighting.

Designers of the Unusual, consisting of Maartje Dros and Eric Klarenbeek, combine social design with technology from an ecological point of view. In their work they search for new meanings in biotechnology to create new infrastructures for local production.

With great thanks to IDFA, Prast&Hoofd and J.C. Art Fund.

Algae Egg Chair in collaboration with Ghyczy

A design icon and of one of the first early plastic (PU) chairs by Peter Ghyczy, as part of the Vitra Collection, remade and robotprinted with our Seaweed based biopolymers. A scope into the future of new ways of fabrication through materials that replace fossil, remediates ecology, addresses and breaks with the current destructive materials we use daily.

The exhibition "Plastic: Remaking Our World" at the Vitra Design Museum examines the history and future of this controversial material. Plastics have shaped our daily lives like no other material: from packaging to footwear, from household goods to furniture, from automobiles to architecture. A symbol of carefree consumerism and revolutionary innovation, plastics have spurred the imagination of designers and architects for decades.

In recent years, many scientists and designers have started exploring materials that are based on renewable rather than fossil resources and often referred to as bioplastics. The exhibition presents a 2022 remake of Peter Ghyczy's Garden Egg Chair (1967) made by Dutch designer duo Klarenbeek & Dros using 3D printed algae-based plastic replacers.

As a whole, the exhibition "Plastic: Remaking Our World" offers a critical and differentiated reassessment of plastic in today's world. Interviews with designers, scientists, and activists underline the importance of an interdisciplinary approach in which politics, industry, science, and design collaborate closely to tackle the plastic problem. While it is true that each of us is a catalyst for change, there will be no simple remedy to this issue. For this reason, the exhibition aims to address the bigger picture of plastic and its complex role in our world: by analysing how we came to be so dependent on it, by reassessing where the use of plastic is essential and where it can be reduced or replaced, and by reimagining possible futures for this contested material.

The Vegan Dress - Collaboration with Studio Iris van Herpen X Magnum

We have celebrated Herpens 15th-anniversary collection 'Meta Morphism' during Paris Fashion Week.
Studio Klarenbeek & Dros was in charge of the 3D printing materials and technology of the Magnum Vegan Printed Dress to set an example of sustainable fashion.

Cacao filaments were specially developed for this collaboration with House of Iris van Herpen to realise a vision of sustainability and circular fashion in haute couture. Using the shells of cacao beans, a waste stream - which are processed in the chocolate factory next to Studio Klarenbeek & Dros - this waste stream containing cacao pigments and starches were combined with sugars and algae, converted into granulates, spun into printable filaments and printed by the studio. Resulting in a local embedded production cycle of fully organic, biobased polymers.

Circo2021 Ketensamenwerking Seaweed Circle

Met de Seaweed Circle initieerde Klarenbeek en Dros een lokale gesloten CO2 neutrale productiecyclus op basis van zeewier. Hiervoor ontwikkelde ze samen met ketenpartners de afbreekbare en voedende plantpot, geschikt voor agrarische toepassing op industriële schaal.

Binnen dit traject lag de focus op spuitgieten van een afbreekbare en voedende plantpot voor de agrarische sector met diverse door Klarenbeek en Dros ontwikkelde granulaten en recepturen.

In de productielijn van zeewierkweek tot biopolymeer word iedere reststroom gebruikt, waardoor deze lokale Noord-Hollandse branche de eerste zero-waste bioplasticproductie heeft geïnitieerd.

De Seaweed Circle leidt tot stimulering van de circulaire landbouw, biedt een model voor uitgifte en verkoop van CO2 certificaten, levert zeer belangrijke eiwitten voor vee- en visvoer en gaat een langdurige binding aan van CO2 in afbreekbare, eco-restoring, duurzame en voedende biopolymeren. Dit materiaal vervangt producten en kunststoffen die nu enkel op fossiele olie gebaseerd zijn en voegt innovatieve circulaire functionaliteit toe.

De droge stromen die na extractie van de voedingsstoffen voortkomen, zoals zeewiervezels en biopolymeren, worden verwerkt tot granulaat door Klarenbeek en Dros voor toepassing in de kunststofverwerkende industrie, bio-design community, en als filamenten voor additive manufacturing, waaronder 3D-printing en robot printing.

'Diatom Glass' Acquired for the permanent collections of Centre Pompidou Paris (F) and Stedelijk Museum Amsterdam (NL)

With this project we show that the material glass - traditionally considered as fossil - can be grown and cultivated, and therefore 'Diatom Algae Glass' changes this paradigm and introduces 'Renewable Glass'.

Climate positive hand blown glass from algae 'Diatom Glass', based on the cultivation and processing of the silicon armoured group of algae named Diatoms.
Our studio is investigating and has shown the potential of growing the algae group 'Diatoms' for the application and replacement of traditional glass. This by converting their frustules, that diatoms grow, into workable and functional glass.
Diatoms are abundant and responsible for most CO2 uptake and oxygen production on our planet.
Though glass is recyclable, its industry leans on fossil resources and emissions. With this research project we show its possible to cultivate specific types of algae, for the cultivation of CO2 negative and climate positive glass.

In collaboration with:
NIOZ, Royal Netherlands Institute for Sea Research on Texel, who generously helped us in strain selection and cultivation of specific local Diatoms, native to the Waddenzee (NL)
Vrij Glas, who helped in development and production of the hand blown glass pieces
Thanks to microphotographer 'Wim van Egmond', who beautifully documented the diatoms of the 'Wadden'
TNO, for the application in the built environment

First outcomes have been shown at Stedelijk Museum Amsterdam at 'It's our F***king backyard', and more will be shown soon by Centre Pompidou.

TNO tests and validates our seaweed materials for the build environment

TNO ondersteunde het onderzoek met expertise op het gebied van testen en valideren van de samples en elementen voor het meerjarig onderzoek naar de mogelijkheden van nieuwe (biobased) materialen met een hoge design-kwaliteit, prefab bouwen en circulaire bouwprincipes, zoals losmaakbaarheid en modulariteit.

Het project toont de kansen van hoe innovatie in bouwmaterialen kan bijdragen aan grote maatschappelijke uitdagingen; op gebied van klimaat, bijvoorbeeld CO2 -en stikstofreductie, maar ook voor een duurzamere inzet van landbouw en de verbinding van de stad met platteland. Het vormt een pleidooi voor opschaling van duurzaam emissieloos bouwen door middel van industrialisatie en systeemverandering in de bouwsector.

De materialen werden op het paviljoen van de Nieuwe Helden, de Exploded View, gepresenteerd op de Dutch Design Week 2021 en tijdens de wereldtentoonstelling Floriade 2022.

De materiaal samples zijn o.a. toegepast in de levende maquette voor het NEMO te Amsterdam 2022, Kamp C te Genk 2023, Possible Landscapes bij natuurpoort de Peel in Deurne 2023.

Seaweed Cycle for The Breakdown Economy Museum Boijmans Van Beuningen

Studio Klarenbeek & Dros has been developing seaweed based biopolymers based on lab grown algae, that enable a remediating and fully circular local production chain, featured in the online (Covid lockdown) exhibition by Boijmans van Beuningen: 'The Breakdown Economy', 'De Afbreekeconomie'. Visit the online exhibition:

The studio has established the 'Seaweed Circle", a local production chain starting with the propagation and cultivation of seaweed embryos and ending with the production of Seaweed based biopolymers, 'Weedware'. Resulting in CO2-binding and biocompatible materials that restore ecology, stimulate biodiversity and break with the current destructive cycle of production.
This material replaces fossil-derived plastics, while at the same time binding carbon, reducing the footprint below zero: 'Algae grow by absorbing carbon and producing complex starches, natural binders, besides a variety of other valuable components, including pigments. These can be used for the creation of a new generation bioplastics and colors. The waste product is oxygen, clean air, at a scale exceeding the output of trees: algae, as the pioneers of evolution, provide 60% of the oxygen production on earth.

In the exhibition for Boijmans van Beuningen, 'The Breakdown Economy' our newest project Seaweed Cycle presents a world without plastic, placed centrally in the exhibition. Our developed material and startup is called Weedware (, at which we introduce a local cultivated and degradable alternative to plastic.

The Breakdown Economy is an exhibition about making and destroying things. It's not about economic growth and efficient production, but about the limitations of this model. How do we destroy everything that we, as humans, have made? In this discussion you can assume a radical position and lump everything together or adopt a more pragmatic attitude whereby a breakdown economy is in balance with nature. What connects all these ideas is not just that things can be done differently, but that they must be done differently.

The recordings for The Breakdown Economy were made at Foundation AVL Mundo. The concept of the online exhibition was conceived and executed together with Koehorst in t Veld and filmmaker Roel van Tour. Exhibitors Studio Klarenbeek & Dros, Atelier van Lieshout, Koehorst in t Veld.

Designers of the Future Award - 3D Printed Crystals with Swarovski

Swarovski and Design Miami announce Klarenbeek & Dros as winners of the Designers of the Future Award, 2019
For the fifth consecutive year Swarovski and Design Miami are pleased to

announce winners of the Swarovski Designers of the Future Award: Shanghai-born installation artist Juju Wang, Dutch design duo Studio Klarenbeek and Dros, and London-based lighting designer Raffe Burrell. The commissioned works, which apply pioneering and sustainable crystal technologies, were unveiled to an influential audience at Design Miami/ Basel, June 2019.

For Home Decor, Studio Klarenbeek & Dros presented a series of 3D printed crystal objects representing the annual reduction of the Arctic icecaps observed between 1980 till present due to global warming, to capture the world's precious ecology for future generations. Eschewing traditional crystal cutting, the designers are working closely with Swarovski's innovation division to champion the possibilities of 3D printed crystal, using the material for the first time ever in Light Sapphire to emulate the Arctic's waters. The objects - when viewed from above - represent the contour of the arctic icecaps as captured by satellites. The bottom of each object represents the first recording and the top shows the current stage. The horizontal layers are representing both icelayers and a timeline

Over the last two years, Swarovski's technicians have developed 3D crystal capabilities to create more detailed structures not possible when cutting crystal in the conventional way. The home objects will work as building blocks, connecting together to create covetable table top objects that reflect the everchanging icecaps, and reaching new heights of fascination and form in a range that expresses unique interpretations of Swarovski's signature sparkle.

Nadja Swarovski, Member of the Swarovski Executive Board, comments: 'We are delighted to announce Juju Wang, Studio Klarenbeek and Dros, and Raffe Burrell as the 2019 Swarovski Designers of the Future. We are excited to see these dynamic emerging talents engage with Swarovski crystal as a creative medium to help shape the future of responsible design, and we look forward to showcasing their innovative work in Basel this June.'

Aric Chen, 2019 Curatorial Director, Design Miami, comments: 'The Swarovski Designers of the Future award has an incredible track record of highlighting emerging talents who go on to make an impact on design. It's exciting to see that legacy continue with Raffe Burrell, Juju Wang, and Studio Klarenbeek and Dros.'

Studio Klarenbeek & Dros will challenge the use of space with their installation, experimenting with 3D crystal printing. 'In this time of big changes, we're not only developing materials, we're not only developing products, but we're also developing the whole infrastructure and the social coherence around it with the aim of positive change, and that's thrilling,' finds the Dutch design duo, whose designs seek to 'bring together local production, people and their environments.'

Van Wier tot Waar - for S.E.A. at Kaap Skil Texel

Klarenbeek en Dros tonen nieuwe materialen op basis van wier uit de Noordzee, vanuit hun expertise en vijfjarig onderzoek naar lokale biopolymeren op basis van algen en zeewier, waar zij de New Material Award mee wonnen. De grondstof van deze nieuwe plasticvervangers wordt gekweekt in zee, ofwel doormiddel van het nieuwe boeren, ook wel zeebouw genaamd.

Het wier heeft om te groeien veel CO2 gebonden en het eindproduct is naast een vorm van CO2 binding: zowel recyclebaar, composteerbaar als circulair. Zo stimuleert het proces de biodiversiteit, en vormt het materiaal een alternatief voor fossiele niet afbreekbare plastics.

Met het oog op een tekort op landbouwgronden en de potentie voor boeren op zee, onderzoekt het duo de mogelijkheden voor het gebruik van gecultiveerde biomassa uit zee, met als doel het stimuleren en ontwikkelen van een nieuwe productieketen, die reparerend, regenererend en herstellend is voor mens en omgeving, met inbegrip van het uitwisselen van kennis, educatie en cultuur. Dit doen ze door de verschillende onderdelen van het proces te visualiseren, waarmee ze de mogelijkheden, potentie en diversiteit van het wier tonen.

Voor S.E.A lieten Klarenbeek en Dros zich inspireren door de collectie van Kaap Skil, maakte zij in samenwerking met NIOZ gebruik van de eerste gecultiveerde wieren uit de Noordzee en presenteren de hieruit gekomen processen en materialen.

De rijkheid van componenten in zeewier, bieden potentie voor een scala aan toepassingen, zoals de brandstof bioethanol, voedsel voor mens en dier en cosmetica en farmaceutische producten. De studio onderzoekt juist vormen van langere koolstofbinding in materialen en producten (en de gebouwde omgeving).

In samenwerking met twee andere NoordHollandse bedrijven werkt Studio Klarenbeek en Dros aan een eerste pilotfabriek, waar het proces is aangetoond om zeewier op te delen in verschillende producten. Te onderscheiden in: 1: De minerale vloeistof uit zeewier, die wordt toegepast als biostimulant, een meststof voor de biologische bloembollenteelt. Hierbij wordt de plant resistenter en zijn reguliere pesticiden niet meer nodig. 2: De Biomassa en biopolymeren. Een vezelhoudend product dat wordt omgevormd naar de bovengenoemde afbreekbare bioplastic.

Algae Lab - Klarenbeek & Dros with Atelier Luma, Luma Arles

Winner New Material Award, Nominee Beasley Design Award, Nominee German Design Award...
Algae Lab is located at the site of LUMA in Arles, and is focusing on the wetland specific bio-based material in order to come to new value propositions. In particular, Studio Klarenbeek & Dros research the potential of algae as an alternative for non-biodegradable plastics. The development of a polymer from algae can be used to grow and create consumables and innovative products. The serie of objects are related to the culture and history of the region, as utensils from the depot of Musee Departemental Arles Antique.

The objects should be conceived to serve the needs of various users and consumers of the museum and region. The laboratory displays the production chain so the visitor can experience the whole cycle of production from the raw material to the final product.

Studio Klarenbeek & Dros on Algae
' Algae produce the majority of oxygen we breath in, by binding carbon dioxides and converting it into biomass, as they absorb carbon (C) and produce O2 as a waste product: clean air.. In a relatively brief period, humans released a vast amount of CO2 into the atmosphere, from organic matter that lay buried in the ground for millions of years. With effects such as global heating, acidification of the oceans as a result, it's important to bind CO2 from the atmosphere as quickly as possible. And this can be done by binding the carbon to biomass. As designers, we love nothing more than producing mass: products and materials. So, for us it's the golden formula. Everything that surrounds us our - products, houses and cars - can be a form of CO2 binding. If we think in these terms, makers can bring about a revolution. It's about thinking beyond the carbon footprint: instead of zero emissions we need 'negative' emissions. '

Ongoing research on Algae of Studio Klarenbeek & Dros
'In our research, we are concerned with binding carbon to biomass and converting algae into a biopolymer. Algae can produce polysaccharides and starches. Instead of using fossil plastics, adding up even more CO2 or biopolymers from corn or potatoes, which is at the expense of our food and land, we're focussing on Seagriculture, the cultivation of for instance macroalga [seaweed] in sea. As it grows, it filters the seawater, absorbing CO2 and producing a starch that can be used as a raw material for bioplastics or binding agents.

After three years of research with Salga Seaweeds, Danvos, Wageningen University, Avans Biobased Lab in Breda and other institutes, we were invited to establish an open research and production lab at the luma Foundation in Arles. Here, since February 2017, we have worked with Luma on social and local production in Arles region. The CO2 emissions and pollution from factories at the mouth of the Rhone are filtered by algae, with the by-product: Biomass. We are attempting to build a bridge between scientific research and the local economy.

We have 3d scanned historical roman glassware found in the river Rhone from the collection of the Musee Departemental in Arles and reproduced them with locally grown algae from this same region. In the Algae Lab, local native species are researched and processed into biopolymers, that can replace fossil plastics. In principle, we can make anything from this local algae polymer: from shampoo bottles to tableware or rubbish bins. Our ambition is to provide local companies, such as restaurants and catered events in the city with tableware from the AlgaeLab.'

The Mycelium Project - Print and Grow

Studio Klarenbeek & Dros are the first in the world who have 3D-printed living mycelium, the root structure of mushrooms. A technology we are developing since 2011. Combining the threadlike network of fungi with local raw materials, enables us to create products with a negative carbon footprint. more ...

Using this infinite natural source as a living glue for binding organic waste. Once it's full-grown and dried, it turns into a structural, stable and renewable material, comparable to cork or wood.

Why now?
Most of our surrounding products are created through intensive industrial processes. We're imprisoned in this chain of waste, both in material fabrication as well as the negative effect on our surroundings due to transportation of resources and goods.
3D-printing just partly provides in a solution, since we can produce locally by connecting nearby 'Makers' through existing web portals. In the Netherlands for example, the available Maker network with 3D-printers is so dense, you can upload a design, and collect it by bike once its finished.
The problem is the applied materials, which are mostly oil based plastics, and industrially produced. The same goes up for 'bioplastics', which also deal with other issues, such as the use of GMO's. Worldwide there are little producers, resulting in extensive transportation. Secondly there is little attention for the working conditions of Makers, as the printers mostly have no filters and are mostly applied in unventilated spaces. This can cause health risks, especially if you consider actual ingredients are kept secret.
As this market is relatively young, the time is now to introduce new possibilities and hand out alternatives.

What makes this unique?
We've searched for ways to use local resources, and implementing growth in the fabrication process. 3D-printers work by gradually melting and layering plastics. Instead of using plastics, we use local land waste, and mycelium as a binder. The machine simultaneously prints the infill and outer shell, which prevents its fresh mycelium and straw mixture from falling apart. After printing, the structure is placed in an incubator to grow and gain strength.

What do we grow?
This technology can be applied in a broad spectrum of applications. We started with the 'Mycelium Chair' as the archetype for a functional design object. Form-wise the chair is inspired on mycelial networks and reflects the unimaginable freedom of 3D printing. The popping out mushrooms are both aesthetic and a 'proof of concept' as you can clearly see the mycelium has successfully grown through its structure.
'Veiled Lady', Mycelium Project 2.0, is printed in one go and inspired by the net structure of its equally named fungus; Veiled Lady. As we've controlled the growth of mushrooms, they're not in conflict with its function as a stool, and hidden as jewelry within its structure.

What is it good for?
The plant material produces oxygen during its life cycle, and our production process eliminates the necessity of heating materials in the printing process, thus reducing the use of energy. Adding up those two facts, combined with the use of local resources and production, it becomes possible to create products with a negative 'carbon footprint'. Instead of wasting less, we strive to absorb emission.
After use, the product is fully compostable, and can be disposed without harming the environment. On the contrary, it will fertilize our surroundings!

Moss Structure N65 - Absorbing Architecture

Mos als fijnstofvreters langs de N65, de rijksweg tussen 's-Hertogenbosch en Tilburg. Klarenbeek & Dros heeft samen met lokale partijen aan de N65 waaronder kwekerij Aad Vermeer de cooperatie Greentings opgericht, die zich richt op levende fijnstofabsorberende en CO2 bindende wanden en overkappingen. Dit vanuit het pilotproject met ArtCoDe, waarbij ze werken aan architectonische ingrepen op en rondom de N65 die ervoor zorgen dat er een reductie van CO2 en fijnstof langs de weg plaatsvindt.

De 'absorberende' architectuur is opgebouwd uit panelen en kaders met een poreuze structuur waar licht en lucht doorheen kan. Het geheel fungeert als een filter en is de beeldende basis voor de groei van mos.
Hiermee ontwikkelen ze multifunctionele plekken zoals een overspanning voor een verkeersader of een bushalte langs de N65 als beschutting tegen fijnstof. Vanuit groene innovatie definiëren Klarenbeek en Dros een nieuwe identiteit en kwaliteiten van het gebied.
De ontwerpers doen al langer onderzoek naar de absorptie van fijnstof door middel van organismen. De modellen die tot op heden zijn getest, blijken gering effect te hebben. Met dit project willen zij via alternatieve experimenten, nieuwe benaderingen en methodes bekijken of een wezenlijk effect kan worden bereikt. Door absorptie vanuit het extreme te benaderen doen zij een poging te komen tot een model voor Nederland, maar ook daarbuiten [Publiek gemaakt], [BKKC].

Kijk op Kogerveld

Voor de herontwikkeling van industriegebied Kogerveld te Zaanstad, werden Klarenbeek en Dros aangetrokken voor een lokale en duurzame gebiedsontwikkeling in opdracht van de Gemeente Zaanstad.

Binnen het ontwerp voor de herontwikkeling van de wijk Kogerveld staan productie en lokale samenwerking centraal. Verschillende inrichtingselementen zijn ontwikkeld met als doel een kleinschaliger en duurzame inrichting van de openbare ruimte te creëren met de focus op het principe van de circulaire economie, waarbij reststromen uit de wijk worden verwerkt in nieuwe ontwerpen, en de krachten en kwaliteiten van lokale ondernemers worden gebundeld.

Inrichtingselementen die zijn vormgegeven zijn de LED TILE, een met zonne-energie aangedreven sfeerverlichting, banken van gerecycled kunststof uit Kogerveld, een nieuwe tegel geproduceerd met gerecycled beton, en groeninrichting gecombineerd met groenadoptie onder beheer en aansturing van een lokale hovenier.

Aan de Zaan, langs het historisch lint wordt op twee plekken verwezen naar de Zaanse geschiedenis. De fietsonderdoorgang wordt voorzien van looplichten achter gelaserde panelen in de vorm van een Zaans rietlandschap. Zo wordt de fietstunnel op innovatieve manier verlicht en veiliger gemaakt.

Het voormalige Noorderbrughoofd wordt een ontmoetingsplek en uitzichtpunt. Doormiddel van een stalen structuur, die tot in de Zaan loopt, kan een bezoeker via een kijker aan de kade de oude Noorderbrug weer over de Zaan zien steken. Het kunstwerk is door studenten van het Pascal College uitgewerkt en word door het Tetrix (college) uitgevoerd.

Krown - A biotech company that grows products

Klarenbeek & Dros are the initiator of the biotech company Krown, as green pioneers scaling new technologies in order to create impact.

Over the years they've been working on initiating and scaling the technology in Europe, designing its blueprint, building its infrastructure and factory. The've designed a mycelium based product collection and realised collaborative projects for their clients, such as 'The Growing Pavilion', designed with Pascal Leboucq of 'The New Heroes' (First shown at the Dutch Design Week, Eindhoven 2019) and 'the Circular Gardin' for Carlo Rati (Fuorisalone, botanical garden Milan, 2019).

Krown combines biotechnology with ecology, named 'Eco-Technology'. Applying biotechnology while respecting nature and its social context. Through holistic thinking and deep research; By understanding and redesigning complex processes, incorporating its possible natural and environmental impact in relation to its political, economical and social context.

Klarenbeek & Dros have been building on implementing and designing the blueprint for growing mycelium based products, incorporating biodesign and biotechnological processes within production. Our mission is to bring this new technology within reach, beside raising awareness, educate and stimulate experiences of the public showing current status of biofabrication and inspire, wonder and tinker on possible future implementations of eco-technology in our environment, and what it would entail for our interiors and built environment.

These mycelium based products are grown, by using mycelium (the underground root structure of mushrooms), water and agricultural waste only, and is therefore one of the greenest technology and eco-compatible materials on the planet. Mycelium is the network of fungal wires, which acts as a natural glue that binds biomass together, resulting in a fully circular material. These products are 'Cradle2Cradle Gold Certified'.

Jut Product

Voor Jut een Product herwaarderen we het eilands eigen ambacht 'jutten'. Grondstoffen die lokaal voorhanden zijn verwerken en gebruiken we, al experimenterend, als basis voor hoogwaardige materialen en producten.

Na grote stormen vinden we hout, wier en plastics op onze kunsten. Op de Waddeneilanden waren vroeger weinig natuurlijke bouwmaterialen beschikbaar. Wat aanspoelde werd gebruikt. Hiervan zien we nog de sporen, zoals juthout dat werd gebruikt als constructiemateriaal voor boerderijen en schapenboeten.

Op onze mobile productiewagen, de Pokkenwagen, kunnen we lokale grondstoffen omzetten tot hoogwaardig materiaal. Het productieproces is kleinschalig en open opgesteld, zodat het publiek zelf deel kan nemen aan de verschillende fases van het proces. Na het jutten gaan we het materiaal drogen, shredderen, zeven en omzetten tot materiaal voor de 3Dprinter, waarmee we een nieuw product kunnen printen; de pok.

De pok verspreidt zicht over de wereld door zich aan een gastheer te verbinden, als bijvoorbeeld een broche aan je kleding. Op deze manier geeft het project inzicht en informatie over toekomstige productieprocessen en mogelijkheden van grondstoffen en de daaraan gekoppelde ecologische impact, waarbij de bezoeker zelf ontwikkelaar is en drager.

Castellum Fectio

De Romeinse vindplaats Fectio, dat rond fort Vechten in Bunnik ligt, is een archeologisch monument van circa 30 hectare groot. Het behoort tot de top 4 van archeologische sites in Europa. De Romeinen hebben op deze plek, over een periode van 300 jaar, 7 verschillende forten gebouwd. Het laatste castellum uit 315 na Chr. is verbeeld in project Thesaurus Fectio.

De naam Thesaurus Fectio verwijst naar de schatkamer die onder de heuvel ligt. Een schatkamer die niet wordt opgegraven maar wordt bewaard voor de toekomst. Een betonnen plint, met een lengte van 1,5 kilometer, geeft de contour van het 3 hectare grote castellum aan. De Limeswegen, de vicus (het dorp rond het castellum) en de Romeinse Rijn zijn elk op een eigen manier verbeeld.

Op de plint (de muren) van het castellum zijn de belangrijkste momenten uit de opgravingsgeschiedenis van Fectio vormgegeven. De kennis van het Romeinse verleden van Vechten is sinds de 16de eeuw sterk toegenomen en is ook vandaag de dag nog aan veranderingen onderhevig. Nieuwe opgravingen en onderzoek brengen nieuwe feiten aan het licht, en al langer bekende feiten worden opnieuw geïnterpreteerd op grond van nieuwe gezichtspunten.

Door gebruik te maken van 3Dscanning, graphic concrete, straaltechnieken, maar ook werkelijk geraapt vondstmateriaal wordt de opgravingsgeschiedenis ervaarbaar en beleefbaar. Het werk toont hoe de archeologie zich heeft geprofessionaliseerd in het documenteren en determineren van vondsten.

Op de vier toegangspoorten en de zuidelijke muur wordt aandacht gegeven aan verschillende opgravingen en veldkarteringen door archeologen (1892-94, 1914, 1920-26, 1946-47 en 2010) en wordt inzichtelijk gemaakt hoe de kennis is vergaard over de verschillende bouwfases van het castellum en over het dagelijks leven van de Romeinse soldaten en de burgerbevolking.

Wachtpost Broekse Sluis - Monument WOI for the Dutch Ministry

Het Monument voor de Nieuwe Hollandse Waterlinie is opgedragen aan de gemobiliseerde soldaten in het gebied van de Nieuwe Hollandse Waterlinie in de periode 1914-1918.

De nieuwe Hollandse Waterlinie is een belangrijke verdedigingslinie in de Nederlandse geschiedenis en recent zijn de Hollandse Waterlinies tot Unesco Werelderfgoed gewaardeerd. Stroken land werden door middel van inundatie onbegaanbaar gemaakt voor de vijand. In opdracht van Ministerie Dienst Landelijk Gebied

Exterior design for public park: Speelbos Nieuw Wulven - Houten, for the Province Utrecht

For a playing park for children 'Speelbos Nieuw Wulven' in Houten near Utrecht, the Netherlands, we created all objects and furniture.

Based on it's cultural heritage, as the romans used to live in this area and built their Fectio fortress around 3AD. Nearly 2000 year later it became a strategic area for the Dutch Waterline (Nieuwe Hollandse Waterlinie) and once again they decided to build a fortress (1870) and found the roman settlement.

We created a series of benches, travelling through wooden construction techniques and habits as through a timeline, each bench representing another era, from 0AD till present.

Besides this we created granite navigation maps. Objects, such as an enlargement of a roman mask, which was found in the area. After we made a 3D scan of the original, we were able to enlarge it, resulting in a lower resolution version of the original mask (realised by Erick den Boer).

Furthermore; a concrete periscope-house and shooting wall both based on the dutch waterline, and a reinterpretation of a middle age settlement also found during archaeological research.

The designteam existed of Eric Klarenbeek, Maartje Dros & Sergio Davila.

Led Leaf

The Led Leaf is a one 5 Watts LED lighting system introducing durable and efficient LEDs with minimal material and low cost production methods in a do-it-yourself package. The leaf itself functions not only as a lampshade, but at the same time as a cooler for the high-efficient power LED.

Kids Climbing Rack - Amsterdam West

A Climbing rack and handles designed and printed by kids from the neighbourhood. For The Beach, County of Amsterdam.

Samen met buurtbewoners en kinderen hebben we tijdens workshops in samenwerking met de Beach, een ontwerp gemaakt voor een speelpodium en een serie zitbankjes voor speeltuin Veldzicht in Amsterdam West. Om het ontwerp zo dicht mogelijk bij het beeld en de intenties van de kinderen te houden dient 3Dscannen van de maquette, digitaal Kleien voor de klimhandvatten en 3Dprinten de mogelijkheid om directe resultaten van kinderen te vertalen naar het gebouwde object.

Tijdens het Makersfestival ontwierpen de kinderen de klimhandvatten, die digitaal werden gekleid en uitgeprint met een 3d-printer. Zowel de ouders en kinderen werkten gedurende het hele ontwerpproces mee, van schetsontwerp tot uitvoering. Ontwerper Breg Hanssen bouwde het speelobject en werd geholpen met verven door buurtvaders en hun kinderen.

In opdracht van the Beach, Stadsdeel Nieuw-West en Gemeente Amsterdam.

Lucid Dream - Crystal Glass Lights

Handblown crystal-glass with high brightness LEDs. The lucid dream shows the ability of glass to transmit light by internal reflection, spreading light energy of LED's on an extreme efficient way throughout its complete surface, as an illuminating soap bubble.

Movie: co-directed by Efrem Stein. We started working together during his performance 'Opgezet', which was based on my animatronic cat Poekie. We thought it would be great to create something together, resulting in this movie. Many thanks to the performers who supported this project! Please take time to see it on youtube at high quality.

Meubilair Nieuwe Hollandse Waterlinie for Ministry of the Netherlands

For the Dutch Waterline. A military defense line, covering the middle part of the Netherlands, our studio is selected to design the identity of the area, including it's furniture, fencing and lighting. Its main defense line counts 85 kilometers, running from Amsterdam till Rotterdam, its function was to protect the west side of the Netherlands.

Liniemeubilair Nieuwe Hollandse Waterlinie for Ministry of the Netherlands

For the Dutch Waterline. A military defense line, covering the middle part of the Netherlands, our studio is selected to design the identity of the area, including it's furniture, fencing and lighting.

Its main defense line counts 85 kilometers, running from Amsterdam till Rotterdam, its function was to protect the west side of the Netherlands.

The waterline Bench indicates the water level of the Dutch Waterline, De Nieuwe Hollandse Waterlinie. A formal defense method in times of threat of the Netherlands, which split the Netherlands in two, running from North to South, to protect the west side of the Netherlands.

Having operated for centuries, being a secret defense tool till the 50'ties of last century, the dutch were able to artificially flood big pieces of land, to isolate their economical centre. This with only around 30 cm of water, soldiers weren't able to see roads, holes, obstacles. It disabled militaries to cross this kilometres wide boarder, as it was to deep to walk through and too shallow for ships.

With GPS, we measured the exact water height in case of flooding, resulting in this series of benches, varying from ground level height, to 1,40 meters, depending on the exact location.

Windlight for John Kormeling's World Expo pavilion Shanghai

For John Körmeling pavilion we developed an autonomous functioning wind powered LED streetlight, with a warm but high light output brought by 20Watt of LED's.

Windlight was presented at the world Expo 2010 in Shanghai. Placed on the Dutch pavilion "Happy Street" by Dutch Architect John Körmeling.
Windlight started as an experimental proposal for city lighting in the Dutch city of Zaandam. It brings a positive, happy atmosphere and was applied in areas that are remote, in transition or under development, where it serves as a temporary mobile happy tool for its transition period.

A lamp floating on its own heat. From 2003 till present we've made numerous Floating lights, for private and commercial clients. The Floating light has been in the collection and produced for several years by

Pixelpoort - Cycling tunnel - Designed with the community

Windmills, multiculturalism, wooden houses, nature, harbours and polders. Over 700 local residents of Zaanstad participated in the tunnel design via our website.

We've designed the 280m long pixelated walls of the Pixelpoort bicycle tunnel in Zaandam (NL) together with Overtreders W ,

Via people submitted images drawn pixel by pixel on the website, illustrating what they were most proud of in their region. These pixels were translated into tiles, and is now realised in the 'bicycle gate' between Amsterdam and Zaandam.

De fietstunnel ligt aan het begin van de belangrijkste toegangsweg voor fietsers van Zaanstad vanaf Amsterdam, en is dus bij uitstek geschikt om iets te vertellen over de plaats die je binnenfietst. Zaanstad heeft een rijke historie: de Gouden Eeuw begon in feite langs de Zaan, waar het allereerste begin van industrialisatie van productieprocessen dankzij de uitvinding van de windmolen al vroeg op gang kwam. Nog steeds is een aantal van de grootste Nederlandse bedrijven in Zaanstad gevestigd.

Twee factoren waren bepalend voor het ontwerp Pixelpoort: de materiaalkeuze en de wens om een moderne stadspoort te ontwerpen die laat zien dat Zaankanters trots zijn op hun stad. Na een rondgang langs bestaande fietstunnels in Zaanstad werd duidelijk dat het enige materiaal dat werkelijk bestand is tegen graffiti en het verwijderen ervan keramische tegels zijn. Het gebruik van een palet van felgekleurde vierkante tegels levert de mogelijkheid op sterk vergrote computerachtige afbeeldingen te maken, waarbij iedere tegel van 10 bij 10cm met een pixel overeenkomt.

Alle inwoners van Zaandam kregen dan ook de gelegenheid hun eigen visie op Zaanstad in een afbeelding te laten zien. Op de website konden mensen pixeltekeningen maken. 800 Zaankanters hebben de moeite genomen hier een tekening in te zenden, die online zijn te bezichtigen. Er zijn hele diverse afbeeldingen gemaakt door allerlei mensen, van kinderen tot kunstenaars. Uiteindelijk heeft het ontwerpteam een selectie van inzendingen versmolten tot een samenhangend geheel, dat vanaf heden langs de Provincialeweg ter hoogte van de Den Uylweg is te bewonderen.

Wie nu van Amsterdam naar Zaandam fietst komt achtereenvolgens langs abstracte patronen, dieren, een Zaanmeermin en het havengebied bij nacht met vissen en vuurwerk. De noordkant (Zaanse kant) van de tunnel laat een bekender beeld van Zaanstad zien: fabrieken langs het water, groene Zaanse huisjes en molens.


For the Lapse in time exhibition at Experimenta in Lisbon Experimentadesign we created a new piece Plié. As a mix between performance and product, we installed the presented works during the opening, starting with an empty space, which slowly converted into the exhibition space, working together with choreographer Nuno Almeida and his students from the dance academy of Lisbon.

3D Curtains

By turning round the order of the net and curtain a 3-dimensional effect is being introduced as a window darkening system.

3D Curtains for a private residence in Belgium, which has been designed by Ooze Architects, at the seaside of Knokke, Belgium, we were asked to design the curtains for the living room and bedrooms.
The living room has a view on the sea, and for this we created 3 layers of 'voile' curtains, working as a 3D panorama, with on every layer different boats in depth.

The backside view of he apartment is poor due to the facing housing block. Therefore we created two layers of curtains. One thick light absorbing curtain, with the dutch dunes, and one layer of a thin voile, with plants and animals. Photographed by Klarenbeek & Dros in the dutch dunes of the island Texel. Especially at night it's difficult to distinguish whether its real or virtual, giving you a feeling of being able to step out of your door, right in the fields.

Deluge 3D Curtains, at Flight of Objects - Salone del mobile Milan, with Drift, Studio Molen and Sebastian Brajkovic.
For the Salone del Mobile we created a landscape titled Deluge consisting out of 2 layers of silk organza, confronting us with a reality and time where nature disasters are breaking records that is either poetic as well as overwhelming and hits you right in the face.

Motel Out of the Blue, Ijburg, Amsterdam

Tijdens de bouwvakvakantie werd in de Amsterdamse wijk IJburg op de bouwplaats van woonblok 18 een tijdelijk hotel en congresruimte Motel Out of the Blue ingericht.

Waar nu huizen en een centrum voor vrije tijd gevestigd zijn, werd een volledig hotel ingericht uit steigermateriaal. Compleet met conferentieruimtes, bibliotheek, restaurant en 50 een- of tweepersoonskamers.

Dit unieke instant hotel was onderdeel van Out of The Blue, het slotprogramma van het vierjarige kunstproject Het Blauwe Huis wat eind 2009 haar deuren sloot.

Eye Jewellery

Eye jewellery was first presented at the Wonder Room of Selfridges in London, UK

and gained unexpected attention worldwide; It has been featured twice in the Times, its video has been viewed over 340.000 times on youtube and got published and broadcasted worldwide; From the Indian Times, ABC, Der Spiegel, being nominated as Top Rated Fashion Trend by ITN to Asia Television with over 18 million viewers.

A contact lens becomes jewellery, such as spectacles ever became a representation of our identity. Our fear for imperfectness makes us modify our surrounding and being, striving for virtual perfection. Not being someone we should be, but someone we could be.
Aesthetics are more and more based on Photoshop's capabilities and slightly becomes the norm for plastic surgery. Eye jewellery shows our scientific capabilities while showing the beauty of imperfection.

Miller, Flowergirl and The odd one out - Perfumes

For Droog Design we created a series of three perfumes; Miller, Flowergirl and The odd one out. Second hand salt shakers were collected, reviving items that got lost due to bankruptcies.

The glass bottles were reused and upcycled by turning them into a perfumes, sold at the Salone del Mobile in Milan. Created with locally found ingredients: From a local distiller, a perfume maker and a windmill.

In times where the food and cosmetic industry is merely using synthetic components, we have to find a new balance in how we treat nature and ourselves. Deluge is based on local, natural and ecological ingredients.

Batch 1 was produced as 'rollers', with glass marbles. Batch 2 was based on roman bottles, handblown in Amsterdam; These bottles give one drop at a time, and don't leak, due to its capillary action.

Alef 0

For the exhibition 'NAT Designing Nature' at MU Eindhoven, we created an autonomous functioning solar powered light seeking burning robot Alef0, saving his energy to burn dots on his journey.

The robot was designed to infect other design pieces present in the exhibition. Based on analog robotics, Alef0 walks while seeking with his eyes for bright light sources to recharge its battery, while simultaneously saving energy to burn dots on his path with it low power electrically heated burning mouthpiece.

About >
Klarenbeek ∞ Dros do special projects, or let's say unusual, for unusual people, projects or purposes. Their studio connects creatives, designers, architects and local crafts. We search for new meaning and principles in technology, resources, objects and spaces, for unexplored connections between materials, production methods, makers and users. Scale and appliance are irrelevant.

Maartje Dros and Eric Klarenbeek form a designer duo combine social design with technology. Their aim is to challenge and explore the use of space by connecting history, crafts and new technologies in archetypical objects to invite and evoke new use of space.

Eric Klarenbeek (Amsterdam 1978) graduated in 2003 at the Design Academy Eindhoven. Since then he has designed for clients such as Droog Design, Marcel Wanders's Moooi, Lidewij Edelkoort, Makkink Bey, Eneco and the Ministry of the Netherlands. He is founder of the ArTechLab at the AKI ArtEZ art academy ( His projects have been exhibited and published extensively. His windlight is presented at the World Expo 2010 in Shanghai and The Floating Light Project was awarded for innovative design at The Design Academy Eindhoven.

'My work is characterized by interaction and innovation. My products can be in motion, react on our emotions or respond on developments in our society. I search for new meaning and principles in objects, for unexplored connections between materials, production methods, makers and users. Every project is a research, resulting in interior and public space appliances and designs.' Eric Klarenbeek.

Maartje Dros (Texel 1980), also a graduate of the Design Academy Eindhoven acts on the use and dynamics on the periphery of space and borders. It forms the base of her work that explores possibilities on use of space and our common grounds. The outcomes requests collaboration between user and space rather than it is giving stage to a sole object. Not only the hardware of a city is being questioned and integrated her designs, the physical outcome can be seen as an expression of social structures.

He and Maartje were selected to design the public space furniture and identity of the New Dutch Waterline, commissioned by the Dutch Ministry for Infrastructure and Environment DLG. A formal defense line of around 85 kilometres, stretching from Amsterdam to Rotterdam, forming a protective ring around the western and economical part of the Netherlands.
At the moment they're working on varying projects, such as the design of a formal Roman Castellum Fectio, established around 4 AD till around 300 AD, commissioned by the Province Utrecht
