About This Home
Featured by The Wall Street Journal and Architectural Digest, Ghost Donkey Ranch was envisioned as a place where the landscape would lead and architecture would follow quietly behind. Spanning 227 acres in the coveted enclave of Knights Valley, set between Calistoga and Healdsburg at the convergence of Napa and Sonoma's most celebrated wine regions, the ranch unfolds from the valley floor to rolling hills beneath a canopy of native oaks. Redwood Creek traces one boundary, while surrounding ranches and storied vineyards reinforce a sense of pastoral seclusion. Set discreetly behind neighboring properties, the ranch is remarkably private. The residence appears almost as a mirage, a refined steel and glass structure clad in stone, rising from wild grasslands. Both grounded and ethereal, it evokes the feeling of a glass walled tent, dissolving the boundary between interior and landscape. Two dramatic hydraulic, airplane hangar style windows open the home entirely to its surroundings, transforming walls into horizons. The estate includes a 4,200 sq ft main house with three bedrooms, two full baths, and one half bath, along with two detached guest casitas, a 10 car motor court, and a four car garage at the main house. More than a residence, Ghost Donkey Ranch is a living system grounded in regenerative principles, a place to live lightly, responsibly, and in harmony with the natural world. The land is home to an assortment of animals, including donkeys, and is maintained without pesticides or chemical agents, water usage is minimal, and native ecosystems are preserved. Ghost Donkey Ranch is a private world of architectural restraint, natural beauty, and a profound sense of place, designed not to be noticed but to be felt.
