Lore & Background

The Stoclet Palace was commissioned by Adolphe Stoclet, a wealthy Belgian financier and art collector, and his wife Suzanne. They hired the 35-year-old Josef Hoffmann, a founding member of the Vienna Secession, to build their mansion. Stoclet had met Hoffmann while overseeing railroad construction in Vienna and shared his avant-garde artistic inclinations. Initially considering Vienna, Stoclet eventually settled on a site in Brussels. The palace was the first residential project for the Wiener Werkstätte, co-founded by Hoffmann in 1903. Hoffmann abandoned past fashions, producing an asymmetrical compilation of rectangular blocks with exaggerated lines and corners. He received artistic licence and an unlimited budget, designing every detail down to door handles and light fittings. Hoffmann even designed a dress for Madame Stoclet so she would not clash with her living room decor. He presented plans in 1905, and construction in three stages was completed in 1911.

Reader's Guide

The Stoclet Palace is significant as a visible turning point from historical styles to modern architecture and as a prototype of the Art Deco style. It features geometric volumes, symmetry, straight lines, concrete covered with marble plaques, finely-sculpted ornament, and lavish interiors including mosaic friezes by Gustav Klimt. The integration of architects, artists, and artisans makes it an example of a Gesamtkunstwerk, a defining characteristic of Art Nouveau. Art historian Paul Dujardin considers it the first true Art Deco building. The mansion has never been open to the public and remains owned by the Stoclet family. It was classified as a historical monument in 1976 and designated a UNESCO World Heritage Site in 2009. In 2024, the Brussels Parliament approved a motion ordering its opening for a maximum of 15 days per year, though implementation remains unclear.
