In November 1997 Evert Crols, Dirk Engelen and Sven Grooten set up an independent design office: B-architecten. It is based in Antwerp. The three designers became acquainted on their courses in Antwerp and Amsterdam. It was mainly the internationally oriented course at the Berlage Institute in the Netherlands that revealed their common design interests.

B-architecten is a team that developed naturally and works innovatively on a wide variety of projects: individual housing, collective housing, shops, offices, public buildings, public spaces, fairstands, exhibition design, theatre design and studies, sometimes in association with others.

The current members of the B-architecten team are : Sarai Bervoets, Natalie Buyse, Evert Crols, Jan De Loof, Ilse De Ridder, Erik Dewulf, Dirk Engelen, Christoph Fischer, Sven Grooten, Pedro Guerra, Stijn Janssens, Sebastiaan Leroy, Nico Linsen, Dries Otten, Thomas Pirenne, Julie Mabilde, Liesbeth Storkebaum, Bette Struyvelt, Kathy Van de Velde, Patrick Verhamme, Jeroen Verrecht and Annemiek Visser.
