View images of one of Frank Lloyd Wright's most famous designs, a private home called “Fallingwater,” in rural Pennsylvania, along with another of his designs, for the Guggenheim Museum in NYC. Frank Lloyd Wright (1867-1959) was an innovative American architect and designer who developed a personal philosophy of design inspired by nature and natural forms. Wright called his approach “organic architecture.” This style emphasizes harmony between a structure and its environment. Even the materials chosen are designed with respect to their individual properties and their relationship to the whole. Wright designed everything from banks to churches.
