About This Home

As of March 2021

Protected by mature & majestic oaks in the sought-after Happy Valley neighborhood, this remarkable estate features a rare combination of privacy, terraced level-land & pristine Mt. Diablo views. Live in the trees surrounded by glass and enjoy spectacular sunrises with the alpenglow on unobstructed 270 degree views of the hillsides. Incredible indoor/outdoor spaces, including a 1,000 sf patio, a level play area, mature gardens, and a pool, this property has it all. With ample storage throughout and a recently-renovated bedroom wing, this home’s primary suite includes an ample private office with stunning views. High-ceilings, a three-car garage, custom wainscotting and recently updated electrical lighting, enjoy luxury living all within a short distance to some of Bay Area’s best schools and Lafayette’s impressive downtown. This property also includes a vintage grass tennis court and a detached 500 sf+ barn that once housed an owner’s horses. Or possibly convert the space into an ADU.
