Fallingwater or Edgar Kaufmann House is a house built for the business man Edgar Kaufmann between 1935 and 1939 after the plans of Wright. It is located in Pennsylvania in the United-States. Wright is in the first persons to create some corbelled constructions and terraces to open the house on nature because environment is a strong point of his architecture.

The house is build on a plateau in reinforced concrete put on rocks, over a waterfall. It porches and terraces advance on the space and the wild nature. Rocks are omnipresent in the house and the breast walls are in rocks. This house has for goal to demonstrate all the circulations which we can have there: the light thanks to plate glass windows; the water thanks to the torrent which flows under the house. We can also remark that the house is in height so that the view on the vegetation is highlighted.
