Frank Lloyd Wright designed this house in 1950 but construction didn't start until 2004; 54 years later. The plan is considered to be 'site specific' because there is a rock outcrop that cuts right through the home. The house is all concrete: the floors, roof, walls, and even the kitchen countertop. There isn't a sheet of drywall to be found. The long delay between drawing the plans and construction turns out to be fortunate because of the many developments in concrete technology and reinforcement. Without post-tension reinforcement, for example, which was not available in Wright's day, the cantilevered sections would be much more difficult to build without problems later on.
The house is located on an island in a lake about 100 miles north of New York City. Because the house is located about 1/2 mile offshore, all the concrete was mixed onsite in small mixers. Consistency between batches was carefully monitored to produce the strength needed for post-tensioning.
Wright typically used wood to add interesting details and to soften the appearance of concrete. He also built in cabinets and even beds, and you will see that in the slideshow.
