In the city center of Erfurt a commercial building with housing. The neighbouring buildings suggested a 4-story concept with a tilted roof. On the ground floor we organized flexible commercial spaces and a passage to the yard with the main acces to the office spaces on the 1st floor, and the appartments of the upper floors.

Two types of roofs were developed, a standart 45° tilted roof with a zinc cover and as an alternative solution a recessed flat roof - with this more modern solution the stairs of the roof maisonettes lead to the terrasses on top.

The façade is characterized by movable woodpanel-elements, whose alternating positions generate interesting changes in the appearance of the house.
