Property Description

Ideally located near the entrance on one of the most coveted streets within the prestigious Diablo Country Club, this exceptional estate spans 1.44 acres of flat, park-like grounds, offering rare privacy, elegance, and resort-style living. A gated circular driveway creates commanding curb appeal, while the thoughtfully designed, predominantly single-level layout features two private wings - ideal for extended family or multigenerational living. The expansive floor plan includes two primary suites, two kitchens, two laundry rooms, an oversized great room, and a formal dining room, all enhanced by recent refinements including new carpet, sliding doors, updated systems, a backup generator, and a resurfaced pool. A four-car garage with a half bath adds exceptional functionality, while the private backyard oasis is an entertainer's dream with an outdoor kitchen, fireplace, expansive lawn, greenhouse, and charming custom playhouse. Located near parks and recreation, within the highly acclaimed San Ramon Valley School District, and offering access to world-class golf, dining, and social amenities at Diablo Country Club, this is a rare opportunity to own a prestigious and beautifully upgraded estate.
