About This Home

As of May 2026

Set within approximately six acres in Occidental's sunbelt, 'Redwood Refuge' is surrounded by redwoods, yet open to light, views and sky. The property combines privacy and serenity in an idyllic setting encased in natural beauty, with vineyard views stretching across the valley. The home functions equally well as a quiet retreat and for large gatherings of family and friends. A complete renovation and expansion designed by Richard K. Pate and built by Hopkin Construction accentuates the home's thoughtful positioning in a grove of majestic redwoods. Each room is oriented to capture dual exposures, bringing in views of redwoods, landscaping, and distant vineyards throughout the day. Natural materials carry through the interiors, with varied wood finishes, custom cabinetry, and concrete flooring with radiant heat.The main living areas include a spacious living room with a high ceiling and a wood-burning stove, and the separate family room has double doors leading to the expansive patio area and pool. The spacious kitchen is designed for gathering, anchored by a twelve-foot island with generous seating and workspace. The kitchen features high end appliances and generous storage, and opens to a large dining area with built in cabinetry. An adjoining breakfast nook with windows on three sides offers stunning views, accentuating the home's connection with nature. All three bedrooms are en-suite and positioned with separation for privacy. The upper bedroom has a balcony overlooking the property and valley beyond. Multiple doorways provide access to a patio, pool, firepit and landscaped grounds designed with intention and scale. The outdoor areas are layered and fully developed, with extensive hardscape, lighting, new solar array, irrigation, and drainage systems designed by JKT Associates. Additional features include an outdoor sauna and shower. An adjacent structure includes an oversized two car garage and workshop; a large room, with balcony and a full bathroom with steam shower, suitable for a gym, home office or art studio; and an observation deck offering commanding daytime views and nighttime stargazing. A storage shed and separate woodshed and storage room provide practical support for the property. While the property is serene and secluded, it is only minutes to the town of Occidental.
