Detail of Ground Floor Fenestration, House of Hector Guimard, 22 Rue Mozart

Hector Guimard's residential mansion in Paris showcases Art Nouveau's ornamental vocabulary applied to domestic architecture. The five tall windows feature wrought-iron grillwork with characteristic whiplash curves and vertical emphasis, set within a cream-colored stone facade. The decorative planters above the fenestration and the molded archways frame the fenestration with sculptural precision. Guimard, best known for his Paris Métro entrances, brought the same organic dynamism and integrated ornamental philosophy to his private residence, demonstrating how the movement's principles extended from public transportation infrastructure to intimate domestic spaces.
