47.74 private acres high above Ridge Road on your own hilltop setting, with sweeping views to the east and south and room to breathe in every direction. Rarely does this much land come with a home built to match it. Designed to work with its site, this one-of-a-kind steel-frame contemporary uses passive solar gain and geothermal heating and cooling for year-round comfort, and is EPA Energy Star certified and Built Green. Inside, a dramatic two-story atrium with skylights and an interior balcony draws natural light deep into over 5,600 square feet with 5 beds and 2.2 baths. A third-floor tower frames the long views, and three fireplaces warm the home in every season. The chef's eat-in kitchen offers granite counters and Sub-Zero appliances, surrounded by exceptional natural materials: cork and triple-laminate glass floors, maple doors and cabinetry, native cherry and purple heart trim, marble, German limestone, and Vermont and Brazilian slate, all under a zinc and tile roof. The primary suite features a raised sitting area with fireplace. A separate studio with its own entrance, breezeway, and bath makes an ideal private office or artist's retreat. Two separate two-car garages, plus a walk-out lower level plumbed for a second kitchen and full bath. Step outside to a sunny, level lawn and garden, then keep going. Over 47 acres of privacy, space, and possibility await.
