A rare opportunity to own the historic R.A. Cox House, designed by renowned architect C. Lewis Kelley in 1925, situated on a 20,000+ SF irrigated corner lot in the heart of the Alvarado and Los Olivos Historic Districts. This iconic Colonial adobe has been meticulously preserved, showcasing restored wood floors, beamed ceilings, oversized moldings, and custom dual-pane windows designed to honor the home's original character. A thoughtful rear expansion adds a stunning family room with a fireplace, seamlessly connecting to the kitchen featuring soapstone countertops, generous cabinetry, and an eat-in dining area. The formal dining and living room is accented by crown molding and a signature arched window overlooking the expansive front lawn with a wood burning fireplace. Both the front and backyard are equipped with timed sprinklers in addition to the irrigation. The backyard is a private oasis with a glass-tiled pool, mature citrus trees, raised organic garden beds, a spacious lawn, and a covered patio ideal for entertaining. The serene primary suite offers French doors to the backyard and an oversized walk-in closet. Two additional bedrooms share an updated bathroom with a steam shower, while an upstairs ensuite bedroom provides treetop views and flexible living space. Additional features include a temperature-controlled wine cellar with dual dedicated A/C units, a garage with 220-amp service and sewer access (ideal for a studio or pool house), abundant storage, and parking for up to 15 vehicles.
