Of all John Lautner's creations, the Hope residence might be the least well known but the most unforgettable. The property was the famed architect's largest undertaking, sprawling across six acres in Palm Springs, California. Built in 1979—and not without controversy, as owners Bob and Dolores Hope reportedly micromanaged the construction to the point where Lautner eventually withdrew —the home has been likened to a mushroom because of its unique shape. It's centered on a large circular opening that exposes the desert sky. Now that the residence has sold, Lautner lovers have a rare chance to peek inside.

Perhaps surprisingly, it took three years for the 23,366-square-foot home to find a buyer. After Bob and Dolores Hope's deaths, the estate was listed in 2013 for a whopping $50 million, a sum that might not seem out of line for a piece of architectural history but is far beyond the average home price in Palm Springs. After two more price slashes, buyers finally scooped up the expansive property for $13 million.

Included in that price are ten bedrooms, 13 baths, and grounds that more closely resemble a country club. The house was made for entertaining, with a pool, a tennis court, putting greens, a pond, and an outdoor fireplace.

There are also plenty of notable features inside—though the listing pictures don't reveal the boulder that juts into the living room.

Aside from its design pedigree, the home is full of cultural history. It's "entertained dignitaries from all over the world," the listing notes. Plus, it was recently the site of Louis Vuitton's Cruise 2016 show.
