Which architect's philosophy was reflected in the statement, "A house must not be on a hill but of a hill"?

The statement "A house must not be on a hill but of a hill" reflects the philosophy of Frank Lloyd Wright, particularly his emphasis on harmony between architecture and the natural landscape. Wright's approach to design was deeply rooted in the concept of organic architecture, which advocates for structures that are in harmony with their surroundings and utilize natural materials that blend into the landscape.

This philosophy is epitomized in his works such as Fallingwater, where the house is not only situated within the natural setting but is also designed to integrate seamlessly with the waterfall and hillside, appearing as though it is part of the landscape rather than simply placed on it. By advocating that a house should be "of" a hill, Wright emphasizes the importance of considering the land's form and character in the design process, leading to structures that enhance and celebrate their environment.

In contrast, the philosophies of the other architects listed differ significantly. For instance, Le Corbusier focused on functionalism and the use of modern materials, while Louis Kahn emphasized monumental forms and light in his architecture, and Norman Foster is known for high-tech design solutions and sustainability within modern urban contexts. Their approaches do not align with the specific notion of integrating architecture with the natural landform as articulated by Wright.
