Build your dream home in the exclusive, gated community of Siena Valley Club--the highly anticipated, master-planned revitalization formerly known as the Brightwater Club. With several developer luxury homes currently under construction in the $4.1M to $5.7M range, this neighborhood is rapidly establishing itself as a premier destination for modern mountain estates. Situated on one of the community's most desirable streets, this premier, flat, south-facing 0.5-acre homesite offers an ideal, easily buildable footprint. Enjoy unobstructed mountain and valley views while backing directly up to the spectacular Robert Trent Jones Jr. designed championship golf course. The location perfectly balances serenity with accessibility, sitting just 10 minutes from the Vail Valley Jet Center and an easy 40-minute drive to the world-class slopes of Vail and Beaver Creek. Surrounded by Colorado's wide-open spaces, 159 Tallgrass provides seamless access to the White River National Forest and private, pristine fly fishing on Gypsum Creek.
