The Zwerchgiebel or Zwerchhausgiebel is in line with the building's outer wall. In the case of an implementation as a dwelling, the corresponding part of the building can protrude from the facade. This distinguishes the dwarf house from the dormer , which is positioned on the roof independently of the outer walls. The roof of the dwelling is often designed as a gable roof. The mid-roof can also be designed as a flat, tent , monopitch or hipped roof . Its ridge runs transversely ( midway ) to the ridge of the main roof. Accordingly, the eaves of the diaphragm and main roof are at right angles to each other.
Dormitories were built in the cities of the late Middle Ages (from the 14th century) as soon as more storage space, less living space, was required within the city wall. At high trusses supporting allowed Binder inserting the cross gables and thus a better exposure of the roof space. Zwerchhäuser developed into a characteristic architectural element of the German Renaissance . They were erected on the roofs of representative buildings and divided large roof areas. During this time they were often decorated with pillars, pilaster strips , cornices , volutes and windows of various shapes. Since the 17th century more and more attics have been used by dwelling houses.
Even today, roof structures are often carried out with dwelling houses. They change a roof landscape much more than simple dormers or skylights . Subsequent roof construction can therefore meet with objections from the building permit authorities or the preservation authorities .
