Answer to Question 1
Wright's approach to domestic architecture was characterized by two related principles: a house should blend with its environment and interiors and exteriors of houses should be visually and physically integrated. The Kaufmann House is an example of architectural integration with the surrounding environment and the merging of natural landscape features with the organic flow of the interior.
