A series of residential buildings and four school buildings have been created by Basel architects Oliver Brandenberger and Adrian Kloter since 2011. They are all characterised by a virtuoso interplay of raw and finely crafted materials. The renovations are also characterised by a subtle merging of old and new. The most recent examples are the kindergarten and the school in Birrwil: here, concrete and wood were combined seemingly without hesitation, resulting in a harmonious, poetic expression.
