Design for Standard Wooden Ceilings (Planchers en Bois 'Standard')

This architectural drawing by Hector Guimard presents a standardized system for wooden ceiling and floor construction, typical of early twentieth-century industrial design thinking. The sheet combines perspectival views, cross-sections, and detailed assembly diagrams to communicate a reproducible building method. Multiple figures illustrate beam placement, support column joinery, and finished surfaces from different angles—a graphic strategy that anticipates modern technical illustration. Guimard's approach to modular construction and visual clarity reflects the period's interest in rationalized design for efficient, economical building practices.
