Hundertwasserhaus

Starting in the early 1950s, however, he increasingly became focused on architecture, writing and reading in public, advocating natural forms of decay.

Bruno Kreisky, the federal chancellor at the time, suggested in a letter dated 30 November 1977 to Leopold Gratz, the mayor of Vienna, that Hundertwasser be given the opportunity to realize his ideas in the field of architecture by allowing him to build a housing project,[3] whereupon Leopold Gratz, in a letter of 15 December 1977, invited Hundertwasser to create an apartment building according to his own ideas.

It features undulating floors,[b] a roof covered with earth and grass, and large trees growing from inside the rooms, with limbs extending from windows.

Medienvertriebsgesellschaft mbH under its business manager Harald Böhm encouraged architect Krawina to legally substantiate his claim as co-creator of the Hundertwasserhaus.

On 11 March 2010, after eight years of litigation, Austria's Supreme Court of Justice ruled Josef Krawina, along with Friedensreich Hundertwasser, to be co-creators of the house with the effect that it is now forbidden for the Hundertwasser Non-Profit Foundation to disseminate any illustration or replica of the house without acknowledging Krawina as co-creator.
