Property Description

Set behind a private gated entrance along the scenic Marsh Creek corridor, this 14.6-acre ranch estate carries a Clayton address but sits at the crossroads of Clayton and Brentwood, roughly 15 minutes from both downtowns, with easy access to shopping, dining, and commute corridors in either direction. The property is built for those who want land with real purpose. Usable acreage supports horses, livestock, or hobby farming, while rolling hillside terrain frames sweeping views and delivers the kind of natural privacy subdivisions simply cannot replicate. The barn is ready for horses or animals of any kind, with equestrian trail access to Round Valley Regional Park right outside your gate, complemented by a detached garage and storage shed. Inside the main house, 3 bedrooms, 3 bathrooms, and a flexible 4th room ideal as a second primary suite welcome you with rich acacia wood floors, soaring ceilings, a coffered formal dining room, and an open-concept kitchen and family room wrapped in custom cabinetry. Solar panels offset the cost of running a property this size. A brand new approximately 1,200 sq ft ADU, 2BD/1.5BA, full kitchen, laundry hookups, never occupied, offers rental income or multigenerational living that's rare at any price. As the day winds down, this property reveals another side of itself. Soft exterior lighting illuminates brand new retaining walls, the hills go quiet, and the wildlife that calls this land home, deer, wild turkeys, and songbirds, remind you exactly why you made the move. This is the kind of stillness that's nearly impossible to find. Acreage · Horse property · Equestrian · Barn · ADU · Gated · Solar · Mt.
