    Flowing floor planFormal living and diningHeated spaNewer roofSingle-story primary suite

    The Sanctuary at Glass Mountain — an exquisitely maintained estate on .82 wooded acres beneath a canopy of 60+ mature trees. A single-story Primary Suite anchors a flowing floor plan with formal living and dining, a butler's pantry/coffee bar, and a chef's kitchen featuring granite, dual pantries, and a Café induction double oven. The remodeled primary bath dazzles with marble, quartz, LED mirrors, a sculptural soaking tub, and a three-head rain shower. Upstairs offers three bedrooms (one vaulted) and two baths beautifully redone in 2024. The resort-style backyard (2021–2022) delivers a heated pool with water slide and tanning beach, a heated spa, and a full Bull outdoor kitchen under a covered patio. The Retreat — a 1,775A± sf freestanding workshop with a self-contained 741 sf upstairs living space (grandfathered) — adds a gym, office, and flexible quarters. Newer roof, updated HVAC, 2019 windows, EV charger. A rare, move-in-ready offering.
