A modern $13.5 million mansion in Park City's exclusive Promontory community features a striking trapezoidal design by Upwall Design that blends seamlessly with the surrounding Uinta Mountains. The 8,200-square-foot home boasts an open floor plan, abundant natural light, and high-end appliances, as well as direct access to hiking and biking trails.

Why it matters

This home exemplifies the growing trend of ultramodern, nature-inspired architecture in luxury mountain communities like Park City, where developers are creating exclusive neighborhoods that allow residents to immerse themselves in the rugged beauty of the landscape.

The details

The home's copper, bronze, and brass-glass facade, designed by Salt Lake City firm Upwall Design, features a trapezoidal shape that appears to nest together like a Russian doll. A glass-railed bridge leads into the open-concept interior, where a massive wall of sloped windows frames the majestic Uinta Mountains. Natural light streams in through clerestory windows, illuminating the quartzite fireplace and the home's extensive use of Alaskan yellow cedar and Indiana limestone. The kitchen features high-end Gaggeneau, Sub-Zero, and Miele appliances, as well as Taj Mahal quartzite countertops and a Fusion Blue quartzite backsplash. A floating staircase leads to the primary suite, which boasts gallery-sized wall space, a statement-making fireplace, and a grand en suite bathroom with bookmatched stone walls and floors.
