We build homes the way we build them for ourselves.

We are Luc and Wout de Wit. Brothers, building together for twenty years. We do not believe in building principles because they sound good. We believe in them because we live in them ourselves.

Architect Wout extended his own house with a biobased rooftop addition. He lives and works there every day. In 2022 Luc built a biobased extension to his home. He soon noticed that he preferred being there in every season.

“We do not want to believe that biobased performs better. We want to prove it.”Luc and Wout de Wit

The team

The people behind the homes.

Luc de Wit

Product developer (Master in Real Estate) | Founder

What I missed in the housing market was direction and long-term thinking. That is why we develop homes that do not only fit today, but still make sense in thirty years.

Wout de Wit

Biobased and passive-house architect (ir. ing.) | Founder

Good architecture is not an aesthetic choice, but a technical one. A home must work in building physics, be comfortable and function for decades without hidden risks.

Jan Geerts

Specialist in healthy and energy-positive living (MSc) | Founder

Healthy living is not a trend. It is a building discipline. What traditional housing often solves with installations, we solve in the shell.

Marc Dankers

Building-technical designer and 3D BIM modeller (ir.)

Level of detail determines lifespan. We model not only what is visible, but also what still has to function in twenty years.

Richard Fielt

Structural engineer

Timber construction demands precision. A structure must do its work quietly, without depending on perfect conditions.

Jeroen Baars

Marketing and Strategy

Biobased building is not a marketing story. It is a substantive choice. Anyone who invests in a home on their own plot deserves transparency and realism.

Vanja de Wit-Ninkovic

Office management

A good building process stands or falls with structure. I make sure planning, communication and documentation are right, so customers always know where they stand.

Enno van Leersum

Construction cost advisor

Quality is not a matter of spending more. It is a matter of making smart choices at the right moments.
