OFFICE Kersten Geers David Van Severen was founded in 2002 by Kersten Geers and David Van Severen. OFFICE is renowned for its idiosyncratic architecture, in which realisations and theoretical projects stand side by side. The projects are direct, spatial and firmly rooted in architectural theory. The firm reduces architecture to its very essence and most original form: a limited set of basic geometric rules is used to create a framework within which life unfolds out in all its complexity.
