1720 Alameda Diablo

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. This home is being reimagined and will be completed and ready for exclusive viewings in late summer 2026.
