The chief features of Wright's architecture included a reduction to a minimum in
the number of rooms, (他把客廳和廚房打通,造成很大空間) the close
association of buildings to their sites, the free flow of space, (流動的空間) the
use of natural building materials, (用天然的建材 如木頭和石頭) and the
development of a truly human scale. The Millard House(萊特在加州設計了四棟花
磚屋,這是其中一棟) at Pasadena, California, built in 1923, exemplified many of
these principles. Taliesin East(東塔里耶森:萊特在美東威斯康新的大本營;
而美西大本營 Taliesin West 就在亞利桑那鳳凰城附近), Wright's house near
Spring Green, Wisconsin did the same, using local stone, gabled roofs(山牆),
and an outdoor garden to reflect the countryside.
In the 1920s Wright drew fabulous plans for several commercial structures
including a skyscraper(摩天樓) for Chicago National Life Insurance and another
to benamed the St. Marks Tower in New York City. Although the former was
completed, the St. Marks Tower, though incorporating some of Wright's most
revolutionary thinking about skyscrapers, was like many of his most exciting
projects, never built.
When the needs of Americans changed during the Depression(大蕭條
時期), Wright changed as well. He turned his attention to low cost housing such
as the Usonian house(美國風格住宅), and a quadruple house, "the Sun
houses," at Ardmore Pennsylvania. These were examples of the residences he
intended for his ideal communities, such as the rural, decentralized Broadacre
City.(廣畝城市) This was Wright's answer to European schemes for densely
populated skyscraper cities. At about the same time, Wright porduced his most
celebrated masterpiece(最著名的經典之作); the daringly cantilevered(懸臂
的) Fallingwater (落水山莊)at Bear Run, Pennsylvania. With increasing
sensitivity to local terrain, he created more complex spatial and structural themes
than any other modernist, whether European or American.
