MVRDV’s Winy Maas sits down with designboom to discuss the making of the kinetic Sombra Pavilion and the 3D printed Biotopia installation at the Venice Architecture Biennale 2025. Before the exhibition’s public opening on May 9th 2025, the Dutch architect, and the M of MVRDV together with Jacob van Rijs and Nathalie de Vries, explained the making and thinking behind the SOMBRA pavilion and the Biotopia installation. ‘It’s nice that the pavilion is not solar. In this case, it’s only the air pressure. What we use is our knowledge of the sun. We work a lot on shadow and light, and create and research complex solar programs. For Biotopia, I imagine a fully recyclable, biological world that combines all the properties we need: energy, oxygen, animals, shelter, light, flexibility, and changeability,’ the architect tells designboom during the interview.

One project uses physics to create shade without electricity, while the other imagines a future where buildings grow like living organisms. The SOMBRA pavilion – designed by a team led by MVRDV founding partner Jacob van Rijs – is at the European Cultural Centre’s Giardini Marinaressa, part of the Time Space Existence show. The Biotopia installation is at the Arsenale, part of the main exhibition curated by Carlo Ratti. Both of them are on view until November 2025. For the pavilion, built in collaboration with with Metadecor, Airshade, and Alumet, the structure turns reused beams into large arches, supported by metal ribs. This frame holds triangular panels fitted with perforated metal screens. The pavilion operates without electricity or motors. It relies on physics: when direct sunlight heats small air canisters located within the structure’s ribs, the air pressure inside increases. This pressure inflates small airbags attached to the panels. As an airbag inflates, it contracts, pulling its corresponding panel closed to create shade. When the sun moves and the canisters cool, the pressure decreases, and the panels reopen.

Progress to building a biotopic world

Heading to the Arsenale of the Venice Architecture Biennale 2025, Winy Maas and his think tank The Why Factory collaborate with visual artist Federico Díaz to sculpt and present BIOTOPIA. The installation is in two parts. First, the 3D printed sculpture made of polymer. The second is an accompanying film documenting the Dutch architect’s research and how he imagines biotopia will be, which brims with self-sustaining systems. The kind of future here makes biology the foundation for all design. It reimagines cities as forests and architecture as something that grows like a tree. The core concept is a global Sponge, or a type of dynamic biomatter architecture. This Sponge would perform functions like cooling the air, filtering water, and generating energy, all while adapting like a living thing.

The sculptural installation with Federico Díaz, called Propagative Structures, gives physical form to the idea of living matter, of architecture built from living organisms. The work emerges from research into biomimicry, or a field of design that takes inspiration from natural systems. The installation’s forms draw on the structure of mangrove root networks, a suggestion of a future where habitats are not built but cultivated like plants. In our interview with the architect, Winy Maas discusses the future of urbanism, our progress to a biotopic world, the use of computational designs and algorithms in architecture, and what lies ahead for MVRDV, to name a few.

Interview with Winy MaAs at Venice Architecture Biennale 2025

Designboom (DB): It’s wonderful to see you here in Venice, Winy. We saw the Sombra Pavilion in the garden on our way here. We also read that it’s kinetic?

Winy Maas (WM): It’s a kinetic structure, yes. It doesn’t need energy. Air pressure is generated by a heat difference within the structure itself. That helps to close or open panels, cooling the building at certain corners or not. That, of course, depends on the sun. It’s good to see it in the afternoon too because they placed it next to a tree, so it stands out. The film will be made in the coming months, so we can see the functioning of this air-driven structure. It’s nice that it’s not solar. In this case, it’s only the air pressure.

What we use is our knowledge of the sun. We work a lot on shadow and light. We create and research complex solar programs. After that, we can start working on the solar panel industry. Sun Rock, for example, which is our project in Taipei for the Taipower Electricity company, is a building covered with solar panels. It’s an example of how we use the sun. It’s a nice project too, and I love it.

DB: So, the Sombra Pavilion is one project of MVRDV here at the Venice Architecture Biennale 2025. In the Arsenale, you have another titled Biotopia under The Why Factory, which is the think tank and research institute that you lead. Here, it comes in two parts. The first a 3D printed model with the visual artist Federico Diaz that explores the idea of living matter in continuous transformation. The other is a movie that documents and visualizes this future. First off, how do you see a biotopic world?

WM: Biotopia is a dream. Imagine a fully recyclable, biological world that combines all the properties we need: energy, oxygen, animals, shelter, light, flexibility, and changeability. There’s a huge list of properties we demand from our materials and surroundings. Biotopia philosophizes and speculates on the idea that if we create a material or combination of materials that can facilitate these needs precisely when desired by humans, nature, or animals, that will lead to a city you can’t yet imagine. I’m pursuing a few things with my Utopia concept.

First, I’m trying to paint a sketch. The seven-minute accompanying film visitors see needs improvement, so it will progress over time, to the next step. Second, I’m creating a timeline sequence of materials, an interesting research project I’ll publish in a book. This timeline will detail all the properties we need, measured in time per second, for an average population density. That’s a crucial part. We calculate what we can do with current materials and what’s possible if certain material innovations occur.

WM (continued): There are three epochs in these steps, with the current epoch of innovation per technology, like improved 3D printing. The entire MVRDV group is part of this research. A lot is already happening; we have old materials and new materials emerging. We see this more and more, with layers of wood combined with glue, like glulam and CLT. We also have more types of sandwich constructions. Materials are becoming collaborative. But what if this collaboration becomes more intense?

Materials could help provide light, others energy, and perhaps they could even move. That’s what this timeline aims to explore, too: what kind of collaborations are needed. We’ll depict these in the final timeline, the Blend, where everything is so interactive and active. It could lead to a completely different type of architecture or urbanism. Finally, we’re developing prototypes. These are diverse. One is 3D printing, aiming to move beyond current prefabrication methods. While prefab is fine, 3D printing offers more flexibility.

DB: We were told that the sculptural installation at the Arsenale was supposed to be made of living organisms instead of 3D printed from polymer.

WM: Yes, and I’m still completely open to it, but that’ll most likely be after the Venice Architecture Biennale 2025. There’s this dream of using 3D printing that involves two components, or three elements, that are not currently part of 3D printing. The first is what we call the material bank. Carlo Ratti adopted this idea, which involved a machine design where you have various materials. You feed these materials into the 3D printer, which could have multiple nozzles – one for concrete, one for stone, one for glass, one for steel, one for minerals, and one for wood.

This allows you to select the desired material as you print, changing nozzles along the printing line. This is part of the design. The second component is the printer itself, which is a mixed printer and an ‘un-printer.’ This allows materials to be changed and adapted. To achieve this, an analyzer scans the surface, determines its composition, and then initiates a destruction operation. This process varies depending on the material. For example, 100% glass is easy to break and can be burned in two steps.

WM (continued): You remove the material, burn it, and the burner sends it to the material bank, from which it can be returned to the printer. This applies to all types of materials. So, we have the mixer, the printer, the ‘un-printer,’ and the material bank. The final component is the monitor, where you design and input data. This input isn’t just for design; it’s also a control mechanism. During printing, you need to monitor the process to prevent cracking.

This can involve adding more water because the printing material is like a pudding that needs to be as fluid as possible for adhesion. Adding more water helps with the drying period, and you can also use other polymers. I can provide the diagram, but I should patent it first. This is the dream, so far. There’ll also be these robots that would be there to help construct these. I also have a sequence of mycelium tests that I want to do with the school in Jakarta.

DB: That was our follow-up question: the use of biomaterials. It seems that you’ve already used them in your recent projects. In line with this, you’ve also had a talk discussing computational design and algorithms in architecture and design. In what ways have you and MVRDV adopted them into your workflow?

WM: We have our specialties as an office and research group. I cannot do everything, so we need to collaborate extensively. I’m proficient in scripting; our office was one of the first to adopt it, and now our department excels in it. Our team is well-trained in computation and computer science, which I believe is a significant asset. We are skilled in space design, like any architect, and we are also strong in visualization.

DB: What do you think is our progress towards a biotopic world?

WM: There’s a wide range of research I’m trying to gather and collect. We have the example of 3D printing and mycelium. I’m also looking into the lignification of lignin from trees to accelerate this process in the farming industry. This would make the material more fluid, more like willow. I’m also incredibly interested in the electrical changeability of materials, like electrical rubber, for instance. In short, it’s a long process, but the beauty of it is fantastic.

DB: Are there other materials you want to work or experiment with? What’s next for you?

WM: I like the lignin and the washing-stone technology. This is a new technique we’re developing with Eindhoven. You add a layer of stone, which washes away, and then it assembles into soil. So, it’s essentially accelerating soil creation through erosion and its distribution. This helps plants grow, especially in shadowy areas. We’ve already applied this concept in Dubai for a new pavilion.

Let’s go back to what you said before we started the interview. We’re sitting in a park, and you asked if I have a relationship with nature. My background already explains it, and I think our architecture is involved in that, meaning nature. I think we make it possible to reconnect people with nature. I like your question about what’s next because that’s the topic of the book we’re making. My lectures are always about what’s next, and they include slides. There are many subjects. I can dream about utopia as a kind of end result, if that’s possible.

Then, I also have to study mobility. I need to consider when I move and what makes sense, so we’re doing a new study on velocity with different industries. We’re checking how the city would look with a certain kind of mobility: if I walk only, or if I have horses, or if I have three types of mobility. I also want to add properties to drones. It’s not about sending packages, which we can already do. We have a drone skycar in Shenzhen, and surveying is another use. But you can also construct. So I ask my collaborators and clients, ‘What can I do if I want to build a house in the sky?’ Just as a hypothesis. We’ll see.
