Designed by architect George Bissell in 1963 as a demonstration house for a nationwide association of cement companies, this house was meant to prove that concrete homes were modern, inexpensive, and easy to maintain. A “concrete ‘mushroom,’ of unsurpassed strength and stability,” said the advertising brochure for the house, “it is a major step forward in the development of minimum-maintenance housing, as well as a satisfying esthetic achievement.”
The first house in the new master-planned community of Laguna Niguel, in Orange County, California, it was visited by thousands of people when it was first built. All concrete and glass, with a floating, scalloped concrete roof, it was unlike any other house in the neighborhood, either before or since. While it didn’t spark a craze for round, all-concrete homes, as its developers may have hoped, it did manage to find sympathetic owners who didn’t tear it down or renovate it beyond recognition.
