An extraordinary turn-key opportunity to fast-track your dream estate in one of Danville's most exclusive private gated enclaves, Diablo Ranch Estates. Just moments from the entrance to Mount Diablo State Park, this premier homesite is ready to break ground at purchase, offering a rare chance to bypass 18+ months of entitlement and design review. Included are thoughtfully designed architectural plans for a striking custom residence offering 4,100+ square feet of living space, 5 bedrooms, 4.5 baths, and expansive outdoor loggias and patios. The home is intentionally situated to maximize surrounding hillside views, privacy, and the property's natural setting, creating seamless indoor-outdoor living. Additionally included is a fully integrated luxury ADU cottage featuring its own chef's kitchen, living area, private bedroom suite, separate driveway, and dedicated yard - ideal for multi-generational living, guests, or long-term flexibility. Designed for modern, healthy living, the location offers immediate access to world-class hiking and biking while remaining close to downtown Danville and top-tier amenities, including The Athenian School and Diablo and Blackhawk Country Clubs.
