Description

Custom-built single-story residence situated within a private gated setting in San Antonio Heights, positioned to capture sweeping valley and mountain views. This 5,200 sq ft, home features 4 ensuite bedrooms and 6 bathrooms, designed with a strong emphasis on scale, flow, and privacy.



The residence showcases refined Mediterranean-inspired architecture paired with a sophisticated, modern interior. A striking entry with oversized double doors opens to expansive ceiling heights, arched windows, and a light-filled open floor plan. Elevated positioning enhances the sense of privacy while providing unobstructed views rarely found in single-level estates.



Formal living and dining rooms provide elegant yet functional spaces for entertaining, while the central living area is designed for seamless indoor-outdoor living. The kitchen features Thermador professional appliances, extensive counter space, custom cabinetry, and a large breakfast bar, opening to a grand great room with fireplace. Retractable glass doors lead to approximately 1,730 sq ft of covered outdoor living, including a spacious loggia overlooking the pool, putting green, and expansive valley backdrop.



The primary suite offers a serene retreat with panoramic views, fireplace, generous walk-in closet, and a spa-like bath featuring dual vanities, a freestanding soaking tub, and a separate walk-in shower. One bedroom has been configured as a private studio with kitchenette and bathroom, offering flexibility for guests, multigenerational living, or extended stays.



The property also includes whole-house LED lighting, an integrated audio system, security cameras, solar panels, electric vehicle charging, and a gated drive with RV parking. The grounds provide ample space for recreation, entertaining, or pets, all within a secure and private setting.



A rare opportunity to own a gated, single-level estate in San Antonio Heights with commanding views, architectural refinement, and modern amenities.
