Bessette was featured in 1958 in the San Diego Evening Tribune as a luxury showcase of its era. Step inside 4,036 square feet of single-level living, where four bedrooms and three-and-a-half baths are arranged around an open, light-filled floor plan. Soaring ceilings and faceted windows dissolve the line between inside and out, culminating in a show-stopping living room framed by over twenty feet of uninterrupted glass overlooking the enchanting backyard. The sparkling pool and private in-ground spa, elevated firepit with sunset and stargazing views, tranquil water feature, and mature landscaping create a resort-style oasis that surpasses most vacation destinations.

Spacious rooms throughout, a 32 panel solar system, a secured backyard perimeter, and commanding north/west views complete this very special property, which represents the pinnacle of mid-century California living. The home is situated in scenic Horizon Hills among the rolling foothills of Mount Helix. This is a rare opportunity to own a pristine example of an architectural era, with the potential for historic designation. Discover an exceptional mid-century marvel on over one acre!
