The Hundertwasserhaus is an apartment building that is uniquely coloured with very interesting architecture. Hundertwasserhaus is a social housing complex built in 1986 in Vienna by architect and artist Friedensreich Hundertwasser. It is located in the Landstraße district, east of the city center. The artist wanted to instill joy and joie de vivre in the 50 apartments of the city’s less affluent people, building the various structures using soft lines. In fact, throughout the complex there are no sharp edges. The facades are painted in bright colors and decorated with colorful ceramics.
In each terrace there are hanging gardens that serve to bring greenery into each home.
Friedensreich Hundertwasser can be defined in all respects as a precursor of sustainable architecture because in times not suspected – the first environmental movements were just emerging – he vigorously exposed eco-friendly theories and realized ‘green’ and energy efficient buildings. Friedensreich Hundertwasser started out professionally as a painter but soon created numerous buildings in which he used vegetation as an architectural element: green roofs, hanging gardens, loggias, terraces and facades are covered with plants. In one of his publications (‘The Tenant Tree’) he affirms that the tree, like man, is a real tenant, it is an integral part of the house and therefore he ‘plants’ it everywhere, faithfully to his principle that the house must be in harmony with nature: "for a more human architecture in harmony with nature".
