Final answer:
Le Corbusier's approach to building design was guided by the principle that form follows function, which means buildings were designed primarily based on their intended use, with functional needs taking precedence over ornamental details. Option A is correct.
Step-by-step explanation:
Le Corbusier, a prominent figure in Modernist architecture, believed that buildings should be designed as efficient 'machines for living.' This approach aligns with the design principle that form follows function, a concept initially popularized by Louis Sullivan. According to this principle, the shape of a building or structure should reflect its intended purpose, putting functional requirements above aesthetic or historical considerations. Le Corbusier's architectural philosophy was expressed through his five points of architecture, which emphasized things like free façades and open floor plans to serve the functional purpose of the space as efficiently as possible.
Modernist architects like Le Corbusier aimed to strip buildings down to their essential forms, eliminating ornamental details to prioritize function. Buildings thus displayed their structural elements and were designed to optimally support the activities to be carried out inside them. This functional approach influenced the layout of spaces within various buildings, such as homes, hospitals, and skyscrapers, where specific spatial requirements were met to accommodate different functions efficiently.
