What architectural philosophy emphasizes that the function of a building dictates its design and form?

The concept of "form follows function" is rooted in the belief that the shape and design of a building should primarily be determined by its intended use. This philosophy emerged in the early 20th century, prominently advocated by architects such as Louis Sullivan and later, Le Corbusier. It suggests that a building's aesthetic appeal should not overshadow its practicality; rather, the design should enhance the utility and purpose of the space it encases.

When applying this principle, architects consider how users will interact with the space, the activities that will take place within it, and how it accommodates those activities efficiently. A well-designed structure will not only be visually appealing but will also provide a practical environment that supports the functions it must serve. Thus, the design choices—such as layout, materials, and structural elements—are all aligned with the functional requirements of the building, leading to a seamless integration of use and form.

This philosophy contrasts sharply with other architectural approaches, which might prioritize aesthetic qualities or stylistic trends without giving due consideration to utility.
