This residence in Oberkotzau is the first building in High Franconia to be built according to the solar house standard. The building architecture follows the principle "form follows energy" and is in perfect harmony with the solar energy concept. A 70° slanted roof with 70 m2 of solar panels faces south to capture the greatest amount of low winter sun and convert it into heat.

All the windows in the building are designed as French doors without balustrades and feature dry bonding of the window sashes and triple glazing. The main sash chamber is also filled with a special heat insulating material to exceed the specifications of the KfW-55 standard.
