Covering almost two decades of work by Roger Boltshauser, this issue takes a look at the Zurich-based architect’s uniquely contemporary manner of expression. With profiles of more than 20 projects conceived since the turn of the century, it outlines Boltshauser’s approach to materials and the methods he uses to reveal their intrinsic constructive and structural possibilities. Among the highlights are the rammed earth Rauch House, a clay observation tower at the Brickworks Museum in Cham, Oerlikon Sports and Swimming Centre, Ozeanium at Basel Zoo, and more. The issue also features a conversation with the architect and Jonathan Sergison, plus an essay by Jesús Vassallo.
