The Rutter Real Estate Group acquired the Atterseehaus in 2010. The house is named after the famous Austrian artist Christian Ludwig Attersee, whose elaborate mosaics on the facade of the building have made it a landmark in the Mariahilferstrasse. H & M is the largest user with its 4000 m² "Vienna flagship store". NH Hotels operates a City-Suites hotel in Atterseehaus. The Mariahilferstraße, with 600 stores, more than 160,000 m² of retail space and over 70,000 pedestrians per day, is the largest and most profitable shopping street in Austria.
