The 23,000-square-foot home was designed by California Modernist architect John Lautner and built to resemble a volcano (including a hole that opens a courtyard to the sky). Some say it really looks like a mushroom. Nice views of the city of Palm Springs and the San Jacinto Mountains. Asking price: $50 million. From the NYT:
The roofline has been described as one of the most distinctive works of architecture in the Coachella Valley. The house has also been likened to a giant mushroom. Its original wood frame burned down during construction, in a fire sparked by a welder. Work was finally completed in 1980. Used mostly as a second home and entertaining space by the Hope family, it can accommodate as many as 300 guests for dinner under an enormous covered terrace. Each January for many years, the family threw a huge dinner party to mark the end of the Bob Hope Classic golf tournament, now called the Humana Challenge. "That was sort of a highlight of the desert social calendar," said Linda Hope, a daughter of the couple.
