Karin Dorrepaal and Saskia Oranje, founders of DOOR architects. DOOR architects stands for open design, because together you get further. A truly sustainable result grows through collective development. DOOR believes in strong strategies and a simple first step. Circular thinking and action is their daily practice. DOOR loves to share knowledge and experience: From making municipal buildings in Eindhoven more sustainable to the circular breeding ground for C-Bèta in Schiphol Valley. From affordable circular homes to their own circular office. Karin and Saskia combine fresh ideas with a realistic approach. They are convinced that boundaries in the construction sector must and can be broken. They intuitively devise new strategies and tools when old mechanisms fail. They see their role as architects broad, where expectations and requirements from resident to contractor come together in a balanced design. It is only good if every stakeholder recognizes himself in the design.
