The futuristic hilltop house, known locally as the "Round House" for its spaceship-like appearance, has been listed for sale for the first time since it was built in 1963.
"It's super quirky," said resident Jessi Adams, who has rented the home for years. "Where else are you going to live in a house that's round?"
The three-bedroom, two-bathroom home is notable not only for its circular design but also for a feature rarely found in residential real estate: it rotates. The structure can turn as much as 320 degrees, allowing residents to change their views and maximize sunlight throughout the year.

"Two old washing machine motors sit inside the belt, one on each side to push it," said listing agent Angelo Baglieri of Marcus & Millichap. "There's an old railroad track which it sits on."
The home's plumbing and utilities run through a central core mounted on a swivel, enabling the house to rotate while remaining fully connected.
For Adams, the rotating feature is more than a novelty.
"Usually in the winter, I face a certain direction. It heats the house," she said. "In summer, I can change the view."

It's the residence that's divided lawmakers in Hillsborough and those who live there. Here's an exclusive look inside the "Flintstone House" in Hillsborough.
The home was built by local builder Sam Harkleroad, who was known for taking on unusual architectural projects.
His grandson, Harold Pozzi, said the rotating design reflected his grandfather's personality.
"It's different. It's a challenge. He loved a challenge," Pozzi said.
The sale includes more than just the famous rotating house. Also on the property are six additional dwellings, including the neighboring "Potato Chip House," named for its distinctive sweeping roofline.

Pozzi said maintaining the property has become increasingly difficult. "At this age, it's hard. I'm at the age where it's too much," he said. The two-acre property is listed for $3.3 million.
Baglieri believes it appeals to several types of buyers, including developers, investors and architecture enthusiasts. "I think it checks a lot of boxes," he said. "The developer box, given how much land there is. The architectural box. The investor box, because they can collect income on the other properties."
Originally constructed for about $17,000, the landmark home nearly met the wrecking ball during construction of Highway 101 in the 1960s.
Instead, it was relocated, preserving one of the North Bay's most recognizable and unusual homes. Now, more than six decades later, the rotating "spaceship house" is once again turning heads, this time as it searches for its next owner.
