Ronald Janssen Architecten

Ronald Janssen Architecten is an Amsterdam architecture office working since 1999 on housing, mixed-use buildings and transformations. The practice positions itself between spatial quality and feasibility, for developers, housing corporations and municipalities, with a preference for buildings that prove themselves through use rather than through images.

The work is organised around mixed-use, residential, transformations and villas, and around nature-inclusive design: green courtyards, communal roofs, nesting habitats and climate-adaptive details are treated as part of the brief. Among the projects are Stadswerf Oostenburg in Amsterdam, the Groenmarkt development made with Bastiaan Jongerius Architecten and Buro Harro, and De Telefoondienst; the office also builds for social housing and care facilities.
