Some properties simply hold land. This one holds your breath. Framed by Longs Peak to the west and the Flatirons to the south, this singular Hygiene estate feels borrowed from a national park and delivers every comfort at an uncompromising level. Built in steel and stone with a solidity that feels less like a home and more like a landmark, this is construction meant to last generations. Park-like grounds, mature plantings, private trails and coveted water rights complete an outdoor setting of rare permanence. Inside, vaulted ceilings, exposed beams and floor-to-ceiling windows bring the mountains into the room. The Bulthaup chef's kitchen raises the standard further: luxury cabinetry, a six-burner Wolf range, dual Miele wall ovens, double Miele refrigerator and freezer, and a waterfall-edge island crowned in polished, Taj Mahal quartzite. The main-level primary suite wakes to Flatirons views, steps onto a balcony and retreats to a spa bath with steam shower, soaking tub and custom walk-in closet. The walkout lower level delivers a private theater, wine cellar, exercise room, wet bar and a self-contained guest apartment. Outside, a full-size pool, hot tub, waterfall, tennis court, covered patio with fireplace, enormous stone fire pit and outdoor kitchen surround a property where privacy feels absolute. A multi-purpose barn with commercial kitchen, Lutron and Savant automation and a commercial-grade generator complete the offering. A second barn makes way for horses, as well. Estates like this aren't built anymore; they're inherited, or discovered once in a lifetime.
