The building, on the prominent urban intersection of the outer Döblinger girdle and Heiligenstädterstraße, begins with a 180m long bolt with which the railway arches of Otto Wagner are overbuilt, which is conducted on the bridge pier in street corner in a continuous motion around the corner and finally ends at Heiligenstädterstraße in a seven-storey office to street level. It encloses a courtyard, which is to be used for common accessible facilities and under which a two-storey underground car park will be built.


The superstructure of the existing brick arches of the disused rail line branch of an office building was to align its structure to the realities of the stock: A curved geometry, different widths of inventory (ca.9m) and superstructure (ca.13m) and limited load transfer options (only in the pier area with intervals of about 15-16m) required a precisely balanced support structure. A supporting structure was select made of inclined supports was selected, lateral and transverse parapet beam and tensioned hollow-core slab ceilings. The spatial bracing happens by a system of radial discs on the brickwork piers and tangential disks at the staircase towers. The building at the Heiligenstädterstraße corresponds in supporting structure a conventional office building with access core and floor supports. A system of trusses carrying the curved ‘Point’, with which the superstructure is coupled to the office building. The installation of the underground carpark must take place while current underground U6 operation and be carried out with little deformation.
