Designed by architect George Bissell in 1963, this house was a demonstration model for a nationwide association of cement companies. It was meant to show that concrete homes were modern, inexpensive, fashionable, and easy to maintain.
A “concrete ‘mushroom,’ of unsurpassed strength and stability,” said the house’s advertising brochure, “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.
