Walls of glass and skylights over every bedroom—that’s what happens when an architect from drizzly England designs a dream house in sunny Los Angeles.

The new construction hit the market this week for $38.5 million on one-acre estate at the end of a cul-de-sac in ritzy Bel Air. Though the solid, stone-clad home is built from limestone and travertine, and features rich, dark marble finishes inside, the London-based architect’s primary material was light, said James Harris of The Agency, a luxury agent who also features on the Bravo TV series “Million Dollar Listing Los Angeles.”

“When you put a British architect in Los Angeles, they love the use of natural light,” Mr. Harris said, referring to Quinn Architects, the firm that designed the mansion, which was listed on Monday. Mr. Harris is marketing the home with Mauricio Umansky and David Parnes, also of The Agency.

The fully-furnished, five-bedroom home opens into a bright atrium with a skylight 40 feet overhead, a floating staircase and views through to the grassy back terrace, according to photos of the home.

Glass lines the back of the  house and provides panoramic views of the Bel Air Golf Course and downtown cityscape.

Sweeping ceiling heights of 15 feet make the home feel light and airy despite the use of thick stone materials throughout.

“The act of making a room with proportion and light was central to the concept of this project,” the architect wrote on its website. The firm did not immediately return request for comment.

Estate Four, led by Italian developer Alessandro Cajrati Crivelli, is behind the project. Mr. Cajrati Crivelli, who was traveling and could not be reached for comment, is responsible for a handful of high-end spec homes in Los Angeles, though his firm is better known for massive commercial and urban renewal developments in places like Red Hook, Brooklyn, and Milan.

He bought the land underlying this latest Los Angeles project in 2012 for $6.59 million and knocked down the existing home, property records show.

The newly built mansion boasts a list of lavish amenities central to Bel Air living, including a 500-bottle, temperature-controlled wine cellar, a fully equipped gym with glass walls overlooking the views, a wellness bar and a master suite with a private master deck.

The raised back terrace features a 65-foot infinity pool and a sunken seating area with a firepit.
