About this home
On top of the ridge at RanchesAt Big Mountain, Lot 16 is an under-construction Hill Country showcase estate positioned on 12.45 private acres with rare 360-degree views stretching toward Packsaddle Mountain, Lake LBJ, Marble Falls, and the surrounding Hill Country.
Carefully positioned and designed to take full advantage of its ridge-top setting, the 6,088-square-foot residence is being built by Keith Wing for luxury ranch living and large-scale entertaining. The home features 5 bedrooms, 5 full baths, 1 half bath, expansive indoor-outdoor living, a resort-style pool, screened outdoor living area, game room, study, and loft.
The homesite offers privacy, native landscape, and long-distance views from one of the community’s premier ridge-top settings. RanchesAt Big Mountain is a private gated luxury acreage community spanning approximately 401 acres with only 27 homesites, offering the space and privacy of ranch ownership with the ease of gated access, private roads, underground utilities, and a cohesive community setting.
Wildlife is present throughout the ranch, including blackbuck, Arabian oryx, fallow deer, and native whitetail. Lot 16 is part of the RanchesAt Reserve Collection, a limited offering of available showcase homes selected for their visibility, setting, and role in shaping the community’s architectural tone.
