Hundertwasser's participation at the IGA (International Gardening Exposition) 1983

With the Vienna Culture Alderman, Dr. Helmut Zilk, acting as a go-between, Hundertwasser was invited by the Directors of the IGA ’83 in Munich to propose a poster design and submit one of his ideas for a more human architecture in harmony with nature.

In the Westpark were realised the architecture model HIGH-RISE MEADOW HOUSE on a scale of 1:20.

On the occasion of IGA Hundertwasser wrote the text “Concrete Utopias for the Green City” and installed tree-tenants in Ganghoferstraße 86 on July 26, 1983.
