One of the most popular buildings in Vienna as well as one of the most unique ones, this house is a must-see for any fan of architecture. The house was designed by Friedensreich Hundertswasser, a painter, sculptor and architect well-known for his original use of colour and form and for his aversion to straight lines and standardization in architecture. He was helped by Joseph Krawina. True to his creator's vision, Hundertwasser House, built between 1983 and 1985 has a facade decorated with bright colours, uneven floors and is covered in greenery (including trees growing from inside the house). When visiting, take a stop in the Kunst und Café coffee house at the ground floor. Inside, you can watch a movie of the architect explaining the ideas behind the creation of his house in person, free of charge.
The café is open daily from 10 a.m. to 6 p.m.
