Art House Vienna

The museum is housed in a renovated 1892 building redesigned by the artist Friedensreich Hundertwasser and opened in 1991. It houses the world's largest permanent collection and only permanent exhibition of his works. The structure reflects the artist's ecological philosophy and architectural ideals through its unique design elements.

The architecture is defined by organic forms, vibrant colors, and a deliberate rejection of straight lines. Notable physical features include undulating floors, colorful mosaics, and the integration of greenery and abundant foliage throughout the building. This style is often described as expressionist or modern architecture.

In addition to the permanent collection, the museum hosts rotating temporary exhibitions of contemporary art. These displays often explore themes related to human and environmental issues, reflecting the museum's broader mission to showcase art in the context of ecological concerns.
