This book is a monographic study of Sigurd Lewerentz, one of the major architects of the Swedish Modern School, who develops a sensitive and distinctive response to the the most important architectural movements of this century. The first section of the volume includes a critical essay by Colin St John Wilson and a previously unpublished essay on the work of the Swedish master by Nicola Flora, Paolo Giardiello and Gennaro Postiglione. The central section contains a catalogue of Lewerentz’s works: about 150 designs and constructions, in chronological order, are presented through detailed descriptions and illustrations, both photographs and drawings. A complete list of works and a bibliography based on research in the archives of Stockholm’s Museum of Architecture conclude the volume. This study of Lewerentz is the most original and comprehensive published to date, with a full treatment of unbuilt projects as well as completed buildings.
