Berliner Dach

Machine-translated from the German article

The Berlin roof is an asymmetrical platform roof. It is a flat or shed roof, slightly inclined toward the courtyard side and covered with sheet metal, wood cement or roofing felt on wooden battens, which, however, gives the observer from the street the appearance of a pitched roof through a steep slope (usually 60 degrees, sometimes also interspersed with decorative gables).
