In April 1991 the KuntHausWien (art gallery) opened its doors, a double monument to the architect and painter Friedensreich Hunderwasser: the museum being an exhibit in itself and an exhibition hall for the varied work of this rebel architect. The house, designed by Hundertwasser and Pelikan in the style of the nearby Hinderwasserhaus, was used from 1892 by the Thonet brothers as a workshop for their world famous bow-wood furniture. There are over 100 different Thonet chairs to try out in the ground-level museum café. The privately-owned KunstHausWien has on two floors about 300 paintings, graphics, tapestries and models of Hindertwasser’s environmentally-friendly architectural projects. Both fulfilled and unfulfilled, and two further floors dedicated to changing exhibitions of internationally famous artists’ work. This fascination architectural dream of forms and colors has a colorful tiled façade with different types of windows on a wavy chessboard pattern background. In keeping with natural feel the floor is uneven a “melody for the feet” designed to stimulate and “uplift” the visitor.
