Created under the supervision of the architect and interior designer Josef Hoffmann, the Stoclet House is a masterpiece of the creative genius of the Vienna Secession through its aesthetic and conceptual programme of Gesamtkunstwerk, through its architectural vocabulary, through its originality, and through the exceptional quality of its decoration, of its furniture, of its works of art and of its garden. It is a remarkably well conserved symbol of constructive and aesthetic modernity in the west at the start of the 20th century.
