Le Corbusier developed the Modulor as an additive proportioning system designed to harmonize architectural elements with human stature. By establishing a scale of measurements based on the human body, he aimed to ensure that buildings incorporated a "human scale" in their design.12

The system functions by using human-based measurements derived from the golden ratio ( $ϕ \approx 1.618$ ) to organize the dimensions and proportions of architectural plans. By applying these mathematical ratios to the human form, Le Corbusier created a standardized yet flexible framework that could be used to determine the dimensions of various building components. This approach allowed for the coordination of structural elements and materials, facilitating more efficient construction while maintaining aesthetic and functional harmony. He famously applied this system to his subsequent projects, including the housing complex La Cité Radieuse in Marseille.13
