First time on the market since 1968 (most likely before you were born) for this incredible and iconic Eichler home designed by legendary architectural firm Jones & Emmons, and built in 1960 during phase 1 of the Greenridge neighborhood development of Castro Valley. Fabulous single level, 4 bedroom, 2 bathroom open air atrium model with massive “pop-top” great room, makes this one of the more coveted designs for its style and functionality. This particular Eichler home embraces the nostalgia of the mid-century modern era, and sure to please those looking for an Eichler home in more original condition including an unaltered floor plan, original cabinetry, closet and cabinet doors in great condition, unpainted wood burning brick fireplace in excellent working order, and gorgeous original mahogany paneling throughout. Other features include a massive 2 car attached garage, an insulated foam roof, and radiant heating with copper lines. All situated on a very large and private lot with deck and patio and easterly views of the hills and canyons.
