We make buildings with character. With timeless beauty and quality. We build with care for people, nature and materials. We make enjoyable buildings that last.

Korteknie Stuhlmacher Architects was founded in 2001 by Mechthild Stuhlmacher and Rien Korteknie. The Rotterdam-based agency has realized a range of projects that, despite their initially limited scale, gained much appreciation and attention in the domestic and foreign press and have been awarded multiple architectural prizes.

All projects combine an integrated sustainable approach with a timeless sense for space, and deep concern about the cultural and physical environment.

In the last years the practice has become an international team of architects focusing on building and research tasks of varying scale and complexity. In the work buildings for education, care, culture and well-being play a central role, as well as (social)housing and private dwellings. Recent project include ambitious restoration, renovation and transformation projects that increasingly deal with building in a complex urban and historical context.
