The ground floor is almost completely superstructed by buildings and mainly used for retail and parking purposes. The rising storeys are divided into four separated but connected buildings, which are set back to different distances from the edge of the block.
The project is an example of a contemporary, sustainable approach and a conscious engagement with the existing architecture from the 1970s that characterises the city in this district.
In the course of the far-reaching refurbishment measures of the nine-storey office building complex, the office floors of initially two of the four high-rise buildings were converted and equipped with a pressure-ventilated staircase as well as a fire brigade lift. The building services were modernised and the underground car park was sealed off by the installation of a new, partially lowered floor slab.
The new, rear-ventilated, curtain-type façade consists of large-format, highly weather-resistant powder-coated white aluminium sheet cassettes. These are structured by widely projecting reveal boxes of the windows, individually manufactured from extruded aluminium profiles. The new, thermally separated and highly heat-insulating aluminium turn-tilt windows optimally meet the current requirements for thermal and sound insulation. The single-storey façade of the multi-storey car park facing Wilhelmsaue was clad with aluminium louvres and given a colour scheme similar to the main façade. A roof terrace of approx. 145 m² was built on the roof of component 3.
The complex also received an appropriate, representative entrance. The lobby and the lift lobbies from the 1st to the 8th floor were furnished with wall cladding made of large-format, real wood veneered panels and plinths made of mirror-polished, black titanium nitrite-coated stainless-steel profiles.
Requirements for barrier-free use of the building were taken into account during the renovation.
