In the 1990s, it underwent extensive renovation by Erste Bank, and the attic was expanded into a two-story space. The property was acquired in 2015 by “Palais Schottenring Immobilien GmbH” and is set to undergo renovation and refurbishment after the current usage by Erste Bank ends in July 2016. By July 2018, a total of 40 luxury apartments will be created, including four penthouses on the roof, which will be developed as single-story units.
