At the eastern entrance to the city and on a level with the two Grundig high-rise buildings south of the railway line, the high-rise marks the start of the new Regensburg district. With 11 full floors and a roof space, it consistently exploits the legal possibilities of the property and the special features of the Bavarian high-rise building guidelines. Commercial premises are located on the ground floor and first floor. Above there are nine floors, each with four apartments. The attic contains storage rooms; due to its low height it does not count as a full floor. The building is just under the 30 m mark. Instead of a safety stairwell, two internal intertwined stairways and a dry riser can be used. Elevators and stairwells share common, naturally ventilated vestibules. Pressure ventilation of the stairwells, the anterooms and the firefighters lift can be dispensed with. The high-rise is realised with a minimum of building technology and development costs.

The facade is given a mineral ETICS with a colored high-quality scratch plaster and wide flanges around the windows. To prevent vertical fire flashover, 1 m high, closed parapets are required between windows. This provokes a change between smaller and larger window formats. Larger openings in the base and the small windows in the attic lead to a vertical progression.
