Description

Welcome to an exceptional custom-built estate in the prestigious enclave of San Antonio Heights, where luxury, privacy, and breathtaking views converge in a truly rare offering. Beyond private gates, a grand wrap-around driveway framed by stately pillar archways creates a striking sense of arrival, surrounded by expansive, manicured grounds offering complete seclusion.



This impressive three-story residence, including a fully finished basement, is thoughtfully designed and served by an elevator accessing all levels. Inside, a dramatic foyer showcases refined architectural details and crown molding throughout. Every bedroom features its own en suite bathroom and walk-in closet, providing exceptional comfort and privacy. Dual primary suites, each with a fireplace, offer luxurious retreats, while additional fireplaces in the formal living room, family room, and dining room bring the total to five fireplaces throughout the home.



The chef’s kitchen is a showpiece, appointed with high-end appliances, generous workspace, a wine refrigerator, and seamless flow to the fully equipped outdoor kitchen, ideal for entertaining. Additional features include a whole-house water softener system and a Generac generator that powers the entire home, ensuring year-round comfort and peace of mind.



The finished basement is an entertainer’s paradise with a private theater, full bar, and game room. Upstairs, enjoy a fully equipped fitness room with steam shower, a spacious loft, and an elegant extended hallway enhancing the home’s open flow and sophistication.



Security and functionality are exceptional, featuring a full surveillance and alarm system with license plate readers. The property offers a garage accommodating up to nine vehicles, along with additional RV parking on the side yard.



The backyard is an entertainer’s dream, showcasing nearly two acres of usable land with a resort-style swimming pool, 62-foot waterslide, jacuzzi, fruit trees, and meticulously groomed landscaping illuminated by over 500 Malibu lights, creating stunning ambiance day and night. Situated on approximately four acres with no possibility of future development behind or alongside, the estate offers permanent privacy and panoramic city views.



A truly rare opportunity to experience luxury living in one of San Antonio Heights’ most coveted locations.
