Hundertwasser-Haus was built in 1988 before we in the U.S had heard of carbon footprints, heat islands in cities,the contamination by run-off .
Embarrassing to say, be we lag badly in our address to the problems created by in-fill in our cities. Below is Hundetrwasser-Haus in Vienna (the photo is from the Hundertwasser-Haus archive)
According to Nigel Dunnett, this building set off a revolution in green roofs in Germany and Central Europe.You can see why- imaginative, practical, whimsical and people oriented. No mid-century minimalism going on here. (Do minimalists like trees? Orchids, and dramatic large-leafed dracaenas in giant pots--of course. But slightly loopy looking trees acting like trees---somehow I don't think so.)
