Standard Construction of Doors and Casement Windows

This technical drawing by French architect Hector Guimard documents standardized door and window construction methods. The plate presents detailed elevation views, cross-sections, and joinery diagrams rendered in precise pen line work—a hallmark of early twentieth-century architectural practice. Guimard's systematic approach to modular design reflects the period's embrace of industrial rationalization. The hand-annotated measurements and assembly details demonstrate how architects translated ornamental vision into manufacturable components, bridging Art Nouveau sensibility with emerging modernist production standards.
