Tectōne is a French architectural firm based in Paris, founded by Pascal Chombart de Lauwe, an architect, urbanist, sociologist, and professor at the École Nationale Supérieure d'Architecture de Paris-Belleville (ENSAPB). The firm operates with a clear vision to integrate environmental and social considerations into building design, reflecting a broader societal shift towards sustainability and transparency.

At the heart of tectōne's philosophy are three core principles: urbanity, frugality, and perenniality. Urbanity emphasizes the importance of human-centered design, prioritizing the needs and behaviors of users. This approach is exemplified in their experience with public consultation and participatory housing projects, which have informed their concept of "maîtrise d'usage" – a focus on usability over aesthetics.

Frugality is about simplicity and sustainability, advocating for low-tech solutions that are easy to maintain and have minimal environmental impact. This contrasts with the high-tech, often costly and carbon-intensive methods traditionally used in construction. Tectōne's projects, such as the restructuring of a heritage building in Paris and the development of stone housing in Fontenay-aux-Roses, illustrate this commitment to environmentally friendly practices.

With a portfolio that spans various projects across France, tectōne is contributing to a more sustainable and user-friendly built environment. Their approach reflects a broader societal desire for a more open, transparent, and environmentally conscious world.
