Just outside the San Marcos city limits, this one-of-a-kind home sits on a beautifully level, tree-covered .51-acre lot with lower property taxes and no HOA. Enjoy a peaceful country setting just minutes from downtown San Marcos, shopping, and IH-35. Designed for entertaining, the home centers around inviting indoor and outdoor living spaces. The front courtyard features a built-in outdoor kitchen with bar seating and generous gathering space, while the private rear courtyard includes an in-ground pool, pergola-covered patio, and room to relax. From the foyer, your view extends through the home to the courtyard and pool beyond. Built with foam-insulated, steel-reinforced concrete panels, this home was designed for exceptional durability, energy efficiency, and low maintenance, helping keep it cooler in summer and warmer in winter. Inside, Saltillo tile floors, rich wood accents, impressive solid wood doors, and coffered ceilings in the kitchen, dining area, and primary suite create a warm, inviting feel. Large sliding glass doors open to the hacienda-style courtyard, making the courtyard a natural extension of the living space. The open kitchen overlooks the living and dining areas and provides abundant counter and cabinet space. The spacious primary suite includes a large walk-in closet and a beautifully renovated bath with an oversized walk-in shower, dual shower heads, and detailed tile work. Two secondary bedrooms share a Jack-and-Jill bath, and a half bath serves guests. Separate HVAC systems and water heaters serve each side of the home for added efficiency. With no restrictions, the property offers flexibility for a primary residence, home-based business, or short-term rental. An RV hookup is already in place, with plenty of room to park an RV, boat, or other recreational vehicles. This is a rare opportunity to enjoy privacy, versatility, and exceptional entertaining spaces just minutes from the conveniences of San Marcos. Note-property in FEMA flood area
