Since falling water is Wright’s greatest essay in horizontal space, it is his most powerful piece of structural drama. The masonary wall of sandstone quarried on the site were laid to resemble the natural cliffs. Frank llyod wright often abstracted a visual element of the landscape this way.. the reinforced concrete, of which falling water’s terrace and canopies are formed, contrasts with the static, immovable stone wall.

It’s a symmetrical open plan. Falling water’s floors and roofs are dramatically cantilevered over the waterfall of Bear Run, a creek in western Pennsylvania. Executed in reinforced concrete, the house’s floating planes echo the stream’s cascading flow. The composition is anchored to the site visually by vertical elements such as stairs and chimneys faced in rough stone and from a nearby quarry. Every detail reinforces Wright’s vision of the exploded box: floors and ceiling expand outward independently, vertical elements extend this movement skyward, and windows meet at the corners of rooms, opening to erode the very notion of containment.
