[3] The sumptuous dining and music rooms of the Stoclet Palace exemplified the theatrical spaces of the Gesamtkunstwerk ("total work of art"), celebrating sight, sound, and taste in a symphony of sensual harmonies that paralleled the operas of Richard Wagner, from whom the concept originated.

Hoffman abandoned fashions and styles of the past and produced a building that is an asymmetrical compilation of rectangular blocks, underlined by exaggerated lines and corners.

[7] The starkness of the exterior is softened by artistic windows, which break through the line of the eaves, the rooftop conservatory, and bronze sculptures of four nude males by Franz Metzner, which are mounted on the tower that rises above the stairwell.

The interior of the building is decorated with marble paneling and artworks,[10] including large mosaic friezes[11] by painter Gustav Klimt (designed by him and implemented on location by Leopold Forstner[12]) and murals by Ludwig Heinrich Jungnickel [de].

[16][17] In 2024, however, the Brussels Parliament approved a motion ordering the opening of the Stoclet Palace to the public for a period of maximum 15 days per year,[18] although it remains unclear when this will be put into practice.
