Why Koti picked this home
This striking single-story home features an expansive private yard and a stunning design by Kai Geschke Architects.
Designed by Kai Geschke Architects, this striking single-story residence occupies nearly an acre within the gates of Spanish Oaks, one of Austin's most prestigious private communities. Positioned along the first fairway of Spanish Oaks Golf Club, the home pairs bold contemporary architecture with warmth, privacy, and everyday livability. Walls of glass fill the interiors with natural light while framing golf course and Hill Country views. Thoughtfully arranged for entertaining and everyday living, the floor plan balances open gathering spaces with well-separated private areas. The owner's suite is positioned as a secluded retreat, while three additional ensuite bedrooms occupy their own separate wing. A dedicated fitness room and adjoining steam room create a private wellness area. At the center of the home, the living and dining spaces flow into a chef's kitchen with premium appliances, double ovens, refrigeration and wine storage, substantial prep space, and a full bar. Upstairs, an additional 591 square feet of finished, climate-controlled space offers flexibility as a media room, home office, studio, playroom, or guest retreat. Designed for year-round enjoyment, the outdoor spaces are anchored by a 60-foot lap pool and spa, covered terraces, and an outdoor kitchen with a built-in grill and smoker. Integrated heaters and ceiling fans allow for outdoor living in every season. Additional features include a three-car garage, covered carport, generator, central vacuum, reverse osmosis water filtration, tankless water heaters, integrated audio, and smart home technology. Spanish Oaks offers 24-hour manned security and exceptional amenities, including miles of hiking trails, the Fish Camp, tennis and pickleball courts, a resort-style pool and pavilion, and Spanish Oaks Golf Club. 12900 Hacienda Ridge presents a rare combination of architect-led design, first-fairway views, resort-caliber outdoor living, and the exceptional lifestyle that defines Spanish Oaks.
