Detail of Windows and Door of House of Hector Guimard, 22 Rue Mozart

Hector Guimard (1867–1942), a leading figure of French Art Nouveau, designed this townhouse on Rue Mozart in Paris's 16th arrondissement as both residence and showcase of his architectural principles. The facade demonstrates Guimard's characteristic ornamental vocabulary: sinuous moldings frame the entrance and flanking windows, their carved surrounds echoing organic forms. Wrought-iron balconies and grillwork display the fluid, asymmetrical lines that define the Art Nouveau aesthetic. Guimard's decorative language—developed through his famous Paris Métro stations and other commissions—transforms functional architectural elements into expressive sculptural compositions. The interplay of white stone against the brick wall surface creates rhythmic visual contrast. This house exemplifies how Guimard integrated ornamentation and structure into a unified artistic vision during the height of European modernism.
