4 Earth 2 Mars Holding B.V. develops Circular Architectural Techniques (CATs)—a modular, regenerative building system that empowers communities to co-create affordable, sustainable habitats using local materials. Rooted in circular Design, Origami, and Geometry (DOG) , CATs&DOG reduce emissions, waste, and construction costs while enabling resilience across diverse environments. We are building toward a future where 1 in every 3 people living in slums and facing the climate crisis is not an option. Our mission is to form cross-sector international R&D partnerships to develop and scale CATs&DOG globally—transforming the construction sector through radical collaboration and disruptive innovation. From slums on Earth to settlements on the Moon, we are redefining what it means to build for people and planet.
I am not just building structures—I’m designing systems that learn, adapt, and endure. My work is grounded in the belief that architecture must evolve from permanence to possibility—from static objects to living systems shaped by collaboration, environment, and time.
After rebuilding homes post-earthquake as a student, I learned that resilience is not about rebuilding what was lost, but building what’s needed next. That idea never left me. It became the foundation for a life’s work focused on rethinking how we build—not just the materials or the methods, but the mindsets behind them.
As a solo founder, I’ve spent the last decade not only developing modular systems like CATs&DOG®, but also holding space for radical collaboration across borders, disciplines, and even planets. Whether through circular geometries or open-source deployment logic, my question is always: How can we make building more human, more adaptable, and more future-ready?
I work best when bridging contradictions: precision and poetry, lunar dust and urban slums, vision and execution. I’m driven not by what is, but by what could be—if we dare to build differently.
If you're looking for someone who sees design as diplomacy, infrastructure as invitation, and architecture as a conversation across time and scale—then we’re already speaking the same language.
