Answer to Question 1
Fallingwater, designed by Frank Lloyd Wright, is an example of architectural integration with the surrounding environment and the merging of natural landscape features with the organic flow of the interior. Wright's modern 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 Lever House, designed by Gordon Bunshaft, is an example of the International style of commercial structures. Employing the characteristics of this style, Lever House exhibited clean lines, geometric form, and an avoidance of superficial decoration, a departure from the classical design of Greek and Roman architecture.
Answer to Question 2
Greek temples, including the Temple of Nike, employed the post-and-lintel design system. With its stepped bases and volute capitals, located on the top of the support columns, this structure is identified as an Ionic temple. The post-and-lintel system has been used for thousands of years to raise a roof and provide open space underneath; however, it doesn't have great tensile strength. The supporting columns must be closely spaced.
