Austria Trend Hotel

The building was constructed in 1980 as a hotel with 54 rooms, two office spaces, ancillary rooms, and a two-story underground garage with 55 parking spaces. The second building located behind it at Graf Starhemberggasse 25 was erected a few years later as an office building. In 2007 and 2009, structural changes were made to the ground floor, and a single-story extension was added to expand the restaurant and breakfast area. The office building was converted into a hotel building with 62 rooms and connected to the hotel on Favoritenstraße with a connecting corridor. A total of 30 additional parking spaces were created in the underground garage. The technical due diligence was based on standard documents, meetings, inspections, and a review of official records. The essential building and facility components were examined without mechanical interventions and test runs. Vasko+Partner's due diligence, led by Christian Steininger, convinced the buyer and new owner, represented by Julia Maichanitsch, to carry out comprehensive thermal renovation of the hotel wing on Favoritenstraße. Vasko+Partner was commissioned to handle the thermal renovation, site supervision, preliminary design, detailed planning, in collaboration with architect Muxel, as well as cost control.

The building is located in a protected zone, and the neighboring structures are significantly older. The ground floor areas had different structures and were partially very lively in design. The dominant facade was modified to better blend the building into its partially historical surroundings. Together with architect Muxel, various facade types were developed, and the idea of "dissolving" the bay windows was proposed. This was achieved by the concept of a "folded" external thermal insulation facade. "The folding creates different vertical lines, resulting in a slightly irregular image that undergoes constant changes for the observer due to sunlight and shadow effects," explains Johann Muxel. On the courtyard facade, a flush external thermal insulation facade with a maximum insulation thickness of 16 centimeters was installed. The leaky windows were replaced, including meeting soundproofing requirements according to OIB 5. The heavily articulated ground floor zone with partial natural stone cladding was demolished and replaced with a flush aluminum-glass portal glazing. The garage entrance gate was moved to the building line, eliminating existing fear spaces.
