The practice of architect Jens Casper covers architectural consultancy, design, research and teaching. A 1998 graduate of RWTH Aachen University with a strong interest in urbanism, Jens has established a practice that focuses on reading, interpreting and intervening in the built environment. His built work includes cultural buildings and venues, exhibition spaces, interiors, and high end residential projects, most of them implemented in listed environments. Carried out in a variety of partnerships and co-operations, his work has been internationally recognised, published, and awarded numerous times. His best known works are the Berlin transformations Boros Collection Residence and Radialsystem III, the residence HHGO in Oldenburg, White Cube Bermondsey in London, Phoenixhalle in Dortmund, and the research project Das Garagenmanifest
