116 Upper River Place Located in the gated Rio Central section of Mystic Shores, this exceptional homesite offers an outstanding opportunity to build a luxury custom home in one of the premier communities on the north side of Canyon Lake. Rio Central features private roads and controlled access, providing an added level of privacy and exclusivity. Homes in this section are subject to architectural guidelines designed to preserve long-term value and maintain a cohesive upscale aesthetic. The minimum living area is 2, 700 square feet for a single-story home (3, 000 square feet for one and a half or two-story designs), with full masonry construction required and high-end roofing materials such as standing seam metal or tile. In addition to the main residence, one accessory structure is permitted, offering flexibility for RV or boat storage, a workshop, craft room, or hobby space (no guesthouse permitted). Detached structures must complement the main home in materials and design, making this an ideal setup for buyers seeking functionality without compromising appearance. Mystic Shores is thoughtfully planned with a strong commitment to land stewardship and conservation, actively encouraging the preservation of indigenous wildlife, the use of native and adaptive plants, and responsible water conservation practices. Dark-sky friendly guidelines help minimize light pollution, allowing residents to enjoy breathtaking Hill Country night skies filled with stars. The community also features a nature preserve river park overlooking the Guadalupe River, offering peaceful walking areas, scenic overlooks, and a serene connection to the surrounding natural landscape. Residents enjoy an impressive lineup of resort-style amenities, including multiple swimming pools, tennis and pickleball courts, a basketball court, clubhouse, walking and nature trails, and a lakefront park with direct access to Canyon Lake, picnic areas, and panoramic Hill Country views. This property offers the perfect blend of luxury building standards, gated privacy, conservation-minded living, and Hill Country lake lifestyle, making it an excellent choice for discerning custom-home buyers and builders alike.
