About Hundertwasserhaus
Completed in 1985, the Hundertwasserhaus was commissioned by the City of Vienna and designed with architect Josef Krawina according to artist Friedensreich Hundertwasser's uncompromising anti-rationalist philosophy: he considered the straight line "godless," so the building has almost none — floors undulate, no two windows are the same shape or colour, and roughly 250 trees and bushes grow out of window ledges, roof terraces and balconies, giving the building its distinctive shaggy, half-wild silhouette.
It remains a functioning residential building with real tenants, so the interior isn't open to visitors — the experience is purely about viewing the striking exterior from the street and the small commercial arcade (Kalke Village) built in the same style directly across the road, with shops and a café continuing the aesthetic.
