Hans-Jörg Ruch (b. 1946) is a Swiss architect. Based in St. Moritz since 1989, Ruch's specialty has been the reconstruction of the grand farmhouses and homesteads of the Alpine Engadin in southeast Switzerland--an architect's dream environment as an epic stage for architectural experiment. Through Ruch's bold interventions, the character of these Engadin houses enters into a fresh interplay with the traditional architecture of that region and with the spectacular backdrop surrounding them. In 2009, the book 'Historic Houses in the Engadin: Architectural Interventions by Hans-Jörg Ruch' brought his work to international attention.
