Stoclet Palace, Private palace in Woluwe-Saint-Pierre, Belgium.

Stoclet Palace is a private mansion at 279–281 avenue de Tervueren in Woluwe-Saint-Pierre, Brussels, built 1905–1911 by Josef Hoffmann for Adolphe Stoclet. Its exterior is an asymmetrical composition of rectangular blocks clad in white Norwegian marble, with bronze strips bordering the forms and windows. A tower nearly 20 metres high rises above the stairwell, crowned by four copper sculptures of nude males by Franz Metzner. The garden side opens with bay windows, balconies and terraces.

Built between 1905 and 1911 under architect Josef Hoffmann's direction, the palace became a key example of Vienna Secession design imported to Belgium. Its construction marked a moment when modern Austrian design ideas reached Western Europe.

Inside, you find elaborate mosaic friezes by Gustav Klimt and furniture that artists from the Wiener Werkstätte designed specifically for each room. These handcrafted details shape the feel of every space.

The palace is privately owned by the Stoclet family and has never been open to the public; even restoration experts were long barred from entering. In 2024 the Brussels Parliament approved a motion to open it for at most 15 days a year, but it is unclear when this will take effect. Visitors can only view the marble facade and the tower from avenue de Tervueren.

Hoffmann even designed a dress for Madame Stoclet to match her living room decor, showing his total control over the overall design. This idea of complete design coordination extended unusually into the owner's personal wardrobe.
