Our Mission

We limit our scope of work in order to focus all our efforts, research and ideas on what we do best. That is our pledge to provide consistent expertise and quality. We are transparent about our limits and surround ourselves with qualified partners whenever necessary.

We question assumptions in order to develop projects which really answer the client’s needs and bring value to their lives and to their environment. We aim at designing spaces which fit people, and not the other way around.

We develop a sustainable architecture. This means that we question the materials and energy use, understand and design the climates in the spaces we shape, and encourage quality, durability or flexibility.

We believe that everyone should enjoy well-designed great spaces, regardless of their budget. We founded two housing cooperatives which provide affordable housing, and offer low-cost products which enable everyone to afford the services of an architect.
