The experimental film work “Flat Roofs for Mussolini“ talks about the Italien Rationalism at Lake Como and the buildings by Guiseppe Terragni, who was an important pioneer of this style and tried to persuade the fascist regime to adopt his architecture as an official style. During a creative period lasting only 13 years, Terragni produced a body of work unique in terms of consistency and density. His buildings conform to the modern and are characterised by a reduction to elementary geometrical basic forms. While his buildings now serve as an important reference for architects such as Peter Eisenmann, they are also glorified and their political dimension is downplayed.
