Upstairs, two additional bedrooms, two full bathrooms, and a generous game room provide exceptional flexibility for family and guests, while preserving the home's distinctive charm and sense of scale. The outdoor living spaces are where this residence truly shines. A generous covered porch and oversized patio overlook a stunning Keith Zars pool framed by mature landscaping, creating a private, resort-inspired setting for leisurely afternoons, entertaining, and al fresco dining. The grounds offer the rare combination of beauty, privacy, and effortless livability that defines exceptional Alamo Heights living. Adding remarkable versatility, the guest quarters above the garage offer approximately 576 square feet of additional living space, including a living/bedroom area and full bathroom. Ideal for guests, a private office, studio, homeschool space, or extended family, this separate living area provides flexibility without compromising the privacy of the main residence.
