Final answer:
In the context of architecture, "organic" refers to a design philosophy where buildings are in harmony with their environment and the lives of their inhabitants, using natural materials and considering the landscape, as advocated by Louis Sullivan and Frank Lloyd Wright.
Step-by-step explanation:
The term "organic" in the context of architecture, as used by Louis Sullivan and Frank Lloyd Wright, refers to a design philosophy where buildings are created to be in harmony with their environment, natural surroundings, and humanity. Organic architecture emphasizes that the form of a building should arise from its setting and purpose, incorporating materials native to its location and respecting the natural landscape.
Wright's belief was that architecture should be designed to meet the needs and enhance the lives of its inhabitants, hence buildings should feel like a natural part of their environment rather than imposing upon it. This approach is perceptible in Wright's famous Prairie Houses, which are designed to complement the flat, expansive Midwestern landscape. Additionally, Sullivan is known for the famous adage "form follows function", reflecting the idea that the shape of a building or object should primarily relate to its intended function or purpose.
