What does the motto "Form follows function" suggest about architectural designs?

The motto "Form follows function," attributed to architect Louis Sullivan, emphasizes that the shape or design of a building should be primarily driven by its intended purpose or function. This idea advocates for a design approach that prioritizes utility and practicality over decorative elements or stylistic trends. By suggesting that function should be the primary consideration in design, it encourages architects to create spaces that serve their intended use effectively, ensuring that the layout, materials, and overall structure align with the activities that will take place within.

This principle has had a significant impact on modern architecture, promoting designs that reflect their use. For instance, an office building might utilize open floor plans and large windows to facilitate collaboration and natural light, showcasing how the function directly informs the architectural form. Giving precedence to function can lead to innovative solutions and a more efficient use of resources, thereby enhancing the overall effectiveness of the design.
