This house on Favoritenstrasse was comissioned by the Zentralsparkasse (a bank) in the middle to late 1970s, for their use as a bank and also as a community centre. The house was designed by Günther Domenig, and he considered this as his final work of art. The house seems to be wedget too tightly between the buildings next to it, and many details were not planned but were put in on the spot, as they were building the house (Source: Wikipedia)
I like it, it’s a cool edition to the feel of Favoritenstrasse. You can find it between Keplerplatz and Reumannplatz on the U1.
