Catja de Haas is a small practice that looks at all aspects of architecture: from conceptual to art, to build projects. From urban planning to furniture. The design is always with people and the environment in mind, looking for situation and client-specific solutions.

We value good design and are very conscious of reusing materials where possible and building sustainably to Passiv Haus standards. We work closely with the client, to develop something truly special, challenging conventional ideas to deliver innovative solutions beyond the ordinary. We are passionate about housing for all and through the Giant Dolls’house are involved in working with refugees and the homeless to raise awareness for these modern-day challenges and trying to find architectural solutions for these in our more urban scale work.
