In 1912, a flat roof terrace was built for the first time in Vienna. The Scheu House, built by Adolf Loos between 1912 and 1913 for the lawyer Gustav Scheu and his wife Helen, was not only the first house built for the architect, but above all one of the first buildings with palace architecture . This feature has caused many conflicts with municipal authorities. The owner had to commit to covering the front with ivy, he did it on the side facing the garden.
For the first time in this building Loos used the rational principle of "terracing" which together with the Raumplan, define the two architectural concepts characteristic of the terraced houses designed by the Czech architect.
Loos applied the principle of terracing and the idea of accessing the terrace, located on the east side of the house, from any of the bedrooms, as a symbol of personal freedom.
