Arb, the team from Berne, has been operating since 1968 and is one of Switzerland's most notable architectural offices, committed to creating innovative residential buildings and housing estates. Typical features of their work are: that future users are involved in the planning; that rooms are arranged so that private and public areas are skillfully separated, yet fully integrated; that outside areas are wholly incorporated, thereby fusing architecture and nature. This monograph will portray the main themes in the work of arb with informative texts and numerous illustrations. It will also provide a detailed catalogue of works, offering a reliable overview of arb's oeuvre for the first time.
