Two architects, Jeanne Della Casa and Sylvie Pfaehler, together with their new partners Michael Perret and Lucile FontaRak, are working on a remarkable oeuvre in Lausanne. In the midst of an urban garden and an ensemble of housing, three timber residential developments have their own poetic radiance. The architects' award-winning works include clear tectonically structured residential buildings in Lausanne and the Lavaux region. Text in German and French.
