17533 Humbug Creek Rd

FIRST TIME ON THE MARKET IN 33 YEARS! A truly one-of-a-kind property on 20 acres, bordered by Humbug Creek and conveniently located just off Highway 26. This custom adobe home features 24-inch-thick rammed-earth walls, providing exceptional insulation and year-round comfort. Custom redwood cabinetry in the kitchen and bathrooms perfectly complements the home’s rustic country charm. Offering approximately 2,500 sq ft of living space, the home includes two main bedrooms, a country kitchen, and a spacious great room with 11½-foot ceilings, plus a 700 sq ft enclosed porch. Mission tiles, hand-cast in place, add additional thermal mass, while handcrafted doors and thresholds highlight the quality craftsmanship throughout. All walls and ceilings are finished with 1x10 pine board-and-batten paneling. The home site overlooks a beautiful meadow surrounded by pines, creating a serene and private setting. The property features a 250-ft-deep well with excellent-quality water at the 60-ft level. Some photos have been enhanced.
