What DOOR architecten does
DOOR architecten is a privately held Dutch architecture firm founded in 2014 by Karin Dorrepaal and Saskia Oranje and headquartered in Amsterdam. The firm specializes in circular, regenerative, and sustainable architecture, with a portfolio spanning social housing renovation, new-build residential, civic buildings, urban planning, and circular interiors. Core intellectual property includes the Flourish Framework (a regenerative design methodology organized around six streams: energy, water, biodiversity, food, materials, and social), the Hoog Over modular circular housing concept co-developed with Hillen & Roosen based on Stewart Brand's S-layers, and the PIT lab — a living laboratory inside Amsterdam's Tuin van BRET used to test circular materials and measure Building Circularity Index performance.
The firm's business model is fee-for-service professional architecture delivered through competitive tenders and direct commissions from Dutch housing corporations (Eigen Haard, Woonin, Mitros, Havensteder, Woonbron, Woonstad, Stadgenoot, Intermaris, QuaWonen, Wonam) and municipalities (Amsterdam, Eindhoven, Krimpenerwaard). DOOR operates consortium and alliance models — notably SCoop (with contractors, installers, and sustainability advisors), the !MPULS alliance, and the Circular Design Collective — to win public-sector work and deliver integrated renovation packages. Beyond fees, Hoog Over is positioned as a licensable modular concept and Ciskin circular facade ambassadorship signals emerging non-fee revenue potential.
The team comprises roughly 25 architects, project leaders, BIM managers, designers, researchers, and administrative staff. DOOR owns no disclosed subsidiaries, has not raised external funding, and in 2025 announced a transition toward a StewardOwned ownership model alongside its 10-year anniversary. All operations are domestic (Netherlands), with no disclosed revenue or app/software product.
