The following thesis concerns Alfons Walde's life and work as an architect. It will give a comprehensive overview about his, until now largely unknown, architectural work. To start, Walde's life, his career and his social environment will be described. Kitzbühel, in the intermediate wartime, is the subject of the controversy between Tradition and Modernism and Walde's drafts are a reflection of that. Tourism and the architectural scene of the 20-50ies build the preliminary part. In providing a complete anthology of all his work, buildings will be categorized into six building types. The main focus lies on the buildings in the mountains and the single-family urban houses. The opposing difficulties of building in the mountains, and the history and meaning of an urban single-family house will be discussed. The Tyrolean movement of protecting the nature (Heimatschutz) and the dispute of architectural styles comprise a large part of this work. Furthermore, a chapter will concern itself with hitherto unknown "Cafes, bars, restaurants and stores" in the center of Kitzbühel. The part "Hotels and schools in the region" will demonstrate very particular colour sketches that were not realized past the design phase. "Public leisure facilities" will give a short overview of Walde's buildings at the "Schwarzsee". The final chapter of this thesis will be "sacral buildings" with its main focus on the mortuary.
