Which phrase is associated with modern architectural design and emphasizes functionality?

The phrase "Form follows function" is a foundational principle in modern architectural design that emphasizes the idea that the shape of a building or object should primarily relate to its intended function or purpose. This principle was popularized by architects like Louis Sullivan, who argued that the design of a structure should stem from its function, rather than adhering to traditional aesthetic standards.

By prioritizing function, architects and designers focus on how spaces will be used, ensuring efficiency and practicality in their designs. This approach contributes to creating spaces that not only serve their purpose effectively but also resonate with users' needs. As a result, the emphasis on functionality helps in creating innovative designs that respond thoughtfully to contemporary life, which is central to the ethos of modern architecture.

In contrast, other phrases do not encapsulate this same concept. "Functionality precedes beauty" suggests a hierarchy but is more about prioritizing one aspect without the strong directness of the principle itself. "Design follows necessity" implies a reactive approach to design based on requirements but lacks the emphasis on the relationship between form and function. "Aesthetics over function" stands in opposition to the foundational principle, suggesting that beauty is prioritized rather than serving the functional needs of the design.
