The collection of models by Peter Zumthor, all from the collection of the Kunsthaus in Bregenz, makes it possible to see and survey (but not to photograph) key examples of his recent work.   The dates must relate to the modrls, not the projects themselves:  exhibition space for a sculpture by Walter de Maia at Dia Beacon (2005) – large, empty and top-lit;  a beautiful, circular hotel in Atacama, Chile (2010); the Perm State Art Gallery, a purely sensual, pod-like space (2012);  the new building for LACMA which sweeps away nearly all the existing buildings on the site to replace them with a new scultural vocabulary (2013);  his ground-hugging project for the Fondation Beyeler (2016).   It’s easy to see why he has such a central place in the Biennale.
