For the permanent exhibition of Hundertwasser's work, the buildings of the former furniture factory of the Thonet brothers (1892) in Vienna's 3rd district were chosen, which offered space not only for a permanent exhibition of Hundertwasser's work, but also for international temporary exhibitions. Between 1989 and 1991, architect Peter Pelikan realised the conversion, sensitively integrating Hundertwasser's visionary ideas into the existing building fabric. The result was a light-flooded porch facing the street and a striking staircase in the inner courtyard, which, together with the exhibition rooms, make the KunstHausWien a walk-in Gesamtkunstwerk in which architecture, art and philosophy merge harmoniously. The museum opened its doors on 9 April 1991 and was privately run until 2008, when it became one of four museums managed by Wien Holding.
Throughout his life, Hundertwasser was intensively concerned with the relationship between man and nature, but also with the connection between art and nature. His work reflects this commitment in many different ways: in his architecture, which is more compatible with nature and people, in his commitment to environmental protection, in socio-political statements in manifestos and through public demonstrations and creative actions with which he drew attention to the ecological dimension of human life.
This attitude still characterises KunstHausWien today: it sees itself as a place that combines art and ecology and addresses the pressing challenges of our time - from environmental and climate protection to sustainability and a more conscious life in harmony with nature. The aim is to conserve resources, return territories to nature, incorporate nature into urban development, promote sensory experiences of nature and support social commitment to a sustainable future.
The award as the first Green Museum in 2018 is a logical consequence of this philosophy, and the Vienna Climate Biennale, which has been organised by KunstHausWien since 2024, is a logical continuation of this commitment.
