More greenery with this unique building, a mixture of Visual Art and Architecture. The Kunst Haus Wien museum in Vienna was established on the basic of the philosophy and artistic principles of the Austrian artist Friedensreich Hundertwasser. The building itself, formerly the Thonet furniture factory, was remodeled according to Hundertwasser's own designs. Here one can experience some of Hundertwasser most intriguing architectural ideas. He believed that "it is good to walk on uneven floors". This unique idea can be seen throughout the museum. "Window racism" is another issue the architect raised. Why should all the windows be the same in one particular building? Also, the one idea of his that has had some impact among modern architects is the concept of "tree tenants".
The odd museum is characterized by its mosaic tiles, a roof covered with earth and grass, and large trees growing from inside the rooms, with limbs extending from the windows.
