The tower was built in 1957, but in 2006 C.F. Møller Architects installed its new head offices in the top five floors of the building. On the roof, a new penthouse storey has been constructed containing a canteen, meeting facilities and a roof terrace. The superstructure is constructed of glass with a pre-patinated copper cladding, which refers to the public baths and, in particular, to the copper-clad spires of the Cathedral nearby.

The superstructure has been raised up to provide visual contact with the street, twelve storeys below. In this way, the terrace becomes a "presentation tray" for the finest urban features in Aarhus: the Aarhus River, the Cathedral and the old coastline.

The actual design studio occupies coherent open storeys, linked by a single long, sculptural stairway that passes through all the storeys.
