The Hundertwasserhaus is a municipal apartment complex built in 1983-1985 in Vienna's 3rd district by Austrian artist Friedensreich Hundertwasser together with architects Josef Krawina and Peter Pelikan. With its riot of coloured facades, undulating floors and rooftop forest, it embodies Hundertwasser's rejection of the straight line and is one of Vienna's most-visited buildings. It is still a private residence with around fifty occupied flats, so the interior is closed to the public and only the exterior can be admired. As of 2026 it remains free to view from the Kegelgasse pedestrian zone, and pairs naturally with the KunstHausWien (Hundertwasser Museum) a five-minute walk away.
The endlessly varied facade with eight different window types, ceramic tiles and mosaics, no two sections alike
The 'no straight lines' philosophy made real in the wavy floors and roughly 250 trees and shrubs whose branches reach out of the windows
Fairy-tale details such as golden onion domes, towers and a water-spouting angel fountain
The Hundertwasser Village across the street, with its inner atrium and the famous 'Toilet of Modern Art'
The KunstHausWien five minutes away, holding the world's largest collection of Hundertwasser paintings and architectural designs
Good to know
CautionIgnore websites selling 'Hundertwasserhaus entry tickets'. The building is a private residence with no interior admission, and viewing the exterior is completely free. The only paid ticket nearby is for the separate KunstHausWien museum.
MannersReal people live here, so do not enter the entrances, stairwells or courtyards, keep noise down, and avoid close-up photos into windows and balconies. Enjoy and photograph the building from the Kegelgasse pedestrian zone.
SafetyPickpockets operate at busy sights and on Vienna's trams, so wear your bag in front and mind your phone and wallet. The passageways around the house and village have deliberately uneven floors, so watch your step.
SeasonIn the summer high season the site gets very crowded around midday, so early morning or late afternoon is calmer. In winter the rooftop trees are bare, so expect less greenery in your photos.
RulesAt the nearby KunstHausWien, last admission is 30 minutes before closing, and the restrooms in Hundertwasser Village are paid. Always confirm current prices and opening hours on the official website before you go.
Practical info
The house stands at Kegelgasse 36-38 (corner of Löwengasse) in Vienna's 3rd district; take tram 1 to the Hetzgasse stop and walk about two minutes, or walk from U3 Rochusgasse or U4 Landstraße/Wien-Mitte. The exterior is free to view around the clock, while the KunstHausWien (Hundertwasser Museum) a five-minute walk away opens daily with paid adult admission (check the official site for current prices and hours before visiting).
