Tableau Graphique d'Appareil Standard (Graphic Table for Standard Apparatus)

This gridded chart by French designer Hector Guimard represents a methodical approach to scale and measurement in architectural planning. Labeled as a "Standard Apparatus," the graph employs a uniform grid system to allow architects to plot dimensions across multiple registers—a practical tool for translating design concepts into buildable form. Guimard, known for his Art Nouveau metro entrances in Paris, here demonstrates the systematic thinking required for mass-operational housing design in the postwar period. The French text indicates this sheet enables graphical composition of floor plans and elevation studies while maintaining proportional accuracy across standardized measurements.
