In this project, not only a luxurious penthouse was to be added as the top floor. The existing 51 one- to four-room flats also had to be extensively renovated. Various new features were added to increase the attractiveness of the residential complexes: underfloor heating, parquet floors and extra sound insulation towards the neighbour and the street. The renovation plan also included converting the building into a KfW 70 efficiency house (KfW 70).
In addition to the spectacular-looking superstructure, all other residential units were also refurbished. The planned features were all newly installed. The entire house is now designated as a KfW 70 efficiency house. The design of the balcony front on the southern side was fitted with an ETICS facade instead of the previous tiles.
