Set across 40 acres of Texas prairie minutes from Round Top, Element Ranch is a private estate where modern architecture, refined comfort, and the natural landscape come together. At its heart is a striking five-bedroom villa, joined by three fully independent three-bedroom guest houses, each appointed to the same exacting standard. Together they sleep more than thirty, with room for entertaining the whole family across generations. The estate feels like a private resort, encouraging appreciation of nature without sacrificing comfort. Outdoor living is on a scale that rivals the residences themselves. Amenities include two luxury pools, a sculptural spa, and spring fed pond. Shaded terraces, an outdoor kitchen and sunken fire pit make entertaining memorable. Expansive windows frame sweeping prairie views, mature trees, native wildlife, and seasonal bluebonnets. Offered fully furnished, Element Ranch will welcome family and friends for years to come. Wildlife exemption in place.
