This extraordinary custom-built estate perched along the shores of Upper St. Regis Lake, with additional frontage on Bear Pond, offers a truly unmatched Adirondack experience. With breathtaking lake and mountain views, ultimate privacy, and direct access to nature, this property stands out as one of the most unique offerings in the Adirondack Park. Built in 1991 using stone, rock, and glass in the classic Adirondack tradition, the estate's design was inspired by Frank Lloyd Wright's cruciform concept, ensuring harmony between architecture and its natural surroundings. At the heart of the home is the impressive octagonal Grand Hall, featuring a massive granite stone fireplace—an ideal space for gathering and entertaining. The exceptional craftsmanship is evident throughout, with no detail overlooked, creating an inviting year-round retreat that includes 4 bedrooms and 4.5 baths. In addition to the main residence, the property features five fully winterized sleeping cottages, each thoughtfully designed with private or shared ''Jack and Jill'' baths, offering comfort and seclusion for guests. A pathway leads to a magnificent boathouse complete with an expansive entertaining deck, kitchen, living quarters, and a bathroom—extending the lakefront experience. Set on over 18 acres of pristine land, this estate also offers the rare opportunity to paddle directly from your property into the famous St. Regis canoe carry, immersing you in the serene beauty of the region. Upper St. Regis Lake, with its storied history and tranquil atmosphere, adds to the prestige and timeless appeal of this remarkable offering.
