The settlement area of Central Switzerland, long shaped by hospitality, military, agriculture, and tourism, has undergone significant changes in recent decades. Here too, the financial services sector is becoming increasingly important, and the metropolitan area of Central Switzerland is increasingly influenced by the dynamics and population pressure of the Zurich center. How have construction and spatial practices changed in the 20th century? What are the major challenges of the present? Which mentalities, economic forces, and political governance bodies will shape the future? This large-format book seeks answers and offers a photographic tour of the architectural work of BSA architects in Central Switzerland from 1920 to the present. The full-page photos, which show the buildings in their everyday surroundings, have been included.
