A fantastic location demands visionary architecture. Few properties illustrate this concept better than the residence featured on our Unique Homes Global 2017 cover.

After searching for an ideal mountain setting in prime resort locations in western states, the owner settled on a mountaintop in Promontory, which offers some of the best views in Park City, Utah. An added incentive came from Promontory’s extensive amenities and services, including two 18-hole golf courses as well as the privacy afforded by the setting. To ensure that this level of privacy would not be disturbed, an additional 35 acres of ranchland near the site were added to the property. “You never need to put the shades down except to block the sun,” shares Alan Long, president of Rising Star Realtors in Park City, who is listing this estate.

Such a singular site also calls for equally significant architecture, and designer Walter Cunningham, who is noted for a cutting-edge aesthetic, was brought onboard. The end result is a dramatic geometric composition that unfolds organically along the mountaintop setting. The intricate design has 30 to 35 different elevations that interrelate, something Cunningham has deftly executed. But what transforms this residence from architectural masterpiece into a work of art are the materials. Serpentine Verde Stone from a quarry in Italy was used extensively throughout, appearing in three different finishes — rough on the walls, brushed on the floors and polished for the countertops. Long says the stone was prized by the Romans, who believed it had healing powers. The use of the same material throughout also creates a subtle continuity.

Expanses of glass under the roof create an interior panorama of sunlight and moonlight. “Every time I walk through the house, I notice something different and that doesn’t happen with other houses. It is more a piece of art than it is a structure,” says Long. Another important facet is proportion, which makes this home eminently livable. The home is listed for $19.5 million.
