Master Hundertwasser has completely transformed the former Thonet bentwood furniture factory in his characteristic style. Today, irregular elements of glass, metal, bricks, wood and ceramic tiles in many colors give a unique character to the formerly inconspicuous building. Opened in 1991, Kunst Haus Wien houses a permanent Hundertwasser exhibition on two floors and two additional floors are devoted to changing exhibitions. On the ground floor, there is a café-restaurant and a shop.

Also on the ground floor is the “Garage”, where artists and creative types deal critically with the theses formulated by Hundertwasser on the topics of sustainability, climate change, recycling and urbanity. And on the lower ground floor, the so-called “Galerie” hosts selected items of young photography.
