Floor-to-ceiling windows fill the homes with natural light, enhancing the open-concept layout and seamless indoor-outdoor connection.

Sustainability is central, passive cooling, attic ventilation, and a high-efficiency HVAC system. A massive 27,000-gallon rainwater collection system supplies 100% of the homes' water. Which has never needed supplemental replenishment from other outside sources.

Set on a fully fenced, ag-exempt 15+ acres, this private and secluded property offers no HOA and exceptional outdoor features, including native stone walls, mature live oaks, a sparkling in-ground pool, and versatile barns. Enjoy a covered patio and upper-level balcony with panoramic views, plus a guest house perfect for visitors, a workspace, or potential rental income.

Conveniently located just minutes from Wimberley and San Marcos, this is a rare opportunity to own a distinctive Hill Country retreat.

At 320 Rancho Encino Dr in San Marcos, you're stepping into a 15.18-acre private retreat designed by A. Gruppo Architects that functions as a personal five-star resort between Wimberley and San Marcos in Hays County. The main residence spans 3,020 square feet across four bedrooms and three full baths, plus a dedicated guest house with its own kitchenette and full bathroom, creating the kind of separation that lets everyone breathe on their own schedule.

The indoor-outdoor flow defines daily life here. Floor-to-ceiling windows frame sweeping Hill Country views across a dramatic double-height family room, while recycled glass countertops in the main kitchen flow directly onto a covered patio and upper-level balcony. Warm wood flooring throughout connects interior spaces with the landscape beyond. The open-concept layout around the kitchen island naturally pulls you from cooking to entertaining to simply sitting with coffee and those panoramic vistas. Multiple living areas mean you can split your day between the main living room, dining spaces, and a dedicated study or home office without feeling cramped.

Leisure amenities anchor the property's resort character. The sparkling in-ground pool sits as the centerpiece of the outdoor experience, backed by mature live oaks and native stone walls that have grown roots over decades. Native plantings, rock outcroppings, and rolling slopes create natural privacy without manicuring the land into submission. A barbecue and outdoor grill are built into the covered spaces, making entertaining effortless.

The sustainability infrastructure is exceptional rather than marketing theater. A 27,000-gallon rainwater collection system supplies 100 percent of water needs with zero supplemental usage required. Passive solar orientation, deep overhangs for summer shade, high-efficiency HVAC, and attic ventilation keep utility bills minimal. The property sits fully fenced on ag-exempt land with no HOA, meaning you own your privacy outright.

For families, this sits within Wimberley ISD, serving Blue Hole Elementary, Danforth Middle, and Wimberley High School. Minutes from downtown Wimberley's restaurants and shops plus San Marcos retail and the outlet mall, location delivers convenience without requiring you to live in town. At $414 per square foot for 3,020 square feet, the per-sqft value reflects the acreage and architectural quality rather than just the interior finishes.

This is where you stop dreaming about Hill Country living and actually do it.
