Hans van der Heijden (The Hague, 1963) is one of the founders of biq. In 1988 he graduated at TU Delft. His graduation project, a large scale urban redevelopment scheme, combined his interest for housing and his experience at the governmental building service and Mecanoo. He established biq in 1994 and is biq's design director.

Hans writes about architecture and lectures and teaches. In 2008 he published the book „Architectuur in de kapotte stad“ (Architecture in the fractured city).
