Conversion and extension of an office building in Vienna’s central 3rd district into a modern residential building.

Four new storeys will be added to the building, which was originally designed by architect Harry Glück in the 1960s, thus allowing the creation of new flats on eight main and two attic floors. The ground floor will continue to provide space for office use. The building’s eye-catching feature is its distinctive curvature at the intersection of three streets – Traungasse, Zaunergasse and Lisztstrasse – which also determines the floor plans of the units. The building will not only be completely renovated inside, it will also get an attractive new façade with Alucobond “ribbons” that capture the light from the surroundings and give the building a white-gold shimmer.
