The special feature of the penthouse level is its four-sided layout linking to two staircases, creating light, sunny offices accessed via a corridor on the shaded side. All the conversion work was managed and supervised by ÖRAG. The moving of the facade, which is protected as an historic monument, and restoration to its original state was effected in close cooperation with the Federal Monuments Office.
The property is located in immediate proximity to the bustling pedestrian zones of Naglergasse and Kohlmarkt, with a U3 underground station virtually outside the front door.
Incidentally: Once the domicile and workplace of cloth fullers, Wallnerstraße was first mentioned as early as the 14th century as "Walichstraße".
