291 Barrington Lane

Nestled within Stonegate—Alamo’s coveted gated enclave—this exquisitely remodeled custom estate blends timeless craftsmanship with modern luxury. Set on a predominantly flat acre on one of the community’s premier streets, the 6,000± sq ft residence features four en-suite bedrooms with walk-in closets, two offices with adjacent half baths, and a richly paneled den that can double as a sixth bedroom. A dramatic split staircase anchors the grand two-story entry, smartly separating guest and main wings. Classic millwork, coffered ceilings, and hardwood floors create warm sophistication, while standout upgrades shine throughout: a magazine-worthy chef’s kitchen with walk-in butler’s pantry, an impeccably designed mudroom, a reimagined laundry room, and thoughtfully refreshed spaces at every turn. Upstairs, the newer spa-inspired primary suite and junior en-suite offer calming, neutral elegance. Behind the scenes, upgraded electrical, newer HVACs, a newer water heater, and enterprise-grade WiFi support modern efficiency. Outside, enjoy serene privacy, mature landscaping, and a resort-style pool and spa perfect for year-round entertaining.
