Hidden behind its own private gates and invisible from the road, this is Salt Lake's rare single-level estate: more than 16,000 square feet on 1.41 flat, wooded, fully fenced acres in Holladay, with one step from the entry. The pedigree runs deep. The original home was designed by Lloyd Platt, the design and engineering force behind Guy Dreier's desert-modern estates, before being rebuilt and expanded over four years with Russell Platt as architect. The owners designed every room themselves, without a decorator, on site daily. Beyond the gates, a tempered-glass entry opens beneath a 24-foot clear cedar barrel ceiling to an indoor rain garden where, at the touch of a button, a curtain of water falls over craned-in granite boulders. No other home in Utah opens this way. Italian tile with hardwood inlays flows throughout the main level. The great room and family room connect through a circular bar, and an entire rear wall of floor-to-ceiling glass frames the pond, waterfall, and pool. The Poliform kitchen, imported from Italy, holds dual Sub-Zero refrigerator and freezer columns, two dishwashers plus a dedicated glassware dishwasher, dual ice makers, and a glass-enclosed, climate-controlled wine room. Three en-suite bedrooms occupy the main level, each in its own wing. The primary suite overlooks the waterfall through walls of glass and holds a steam room and a steel-reinforced dressing room with a built-in safe that doubles as a secure room. At the front of the home, a circular glass-wrapped office has its own client entrance. Upstairs, 2,244 square feet are dedicated to entertaining: full bar, game room, theater-ready media space, and walkout deck. The walkout lower level includes a motorcycle lounge with its own ride-in ramp, and the heated eight-car garage is lift-ready with a workshop. Two heated driveways, each with its own gate, complete the arrival. Outside, every element was designed for year-round enjoyment. A heated pool and spa are accented by six arcing lawn jets, while a lighted tennis court converts for pickleball. A fire pit and dramatic fire feature wall create inviting gathering spaces, and the 1,138-square-foot pool house/ADU offers a full kitchen, two baths, and its own private entrance. Radiant heat runs through the home and every walkway, driveway, and patio, backed by redundant forced-air HVAC, Lutron lighting and shades, and a 48kW backup generator. There is no HOA. Big Cottonwood Canyon is minutes away; Salt Lake City International is an easy drive. Offered turnkey with furniture included and art negotiable. Private. Architectural. Irreplaceable. A true one-level estate.
