    FIRST TIME ON THE MARKET: Recently featured by Architectural Digest, this masterwork by San Diego architect Kendrick Bangs Kellogg resides high atop its 40-acre Valley Center parcel offering 360-degree views through expansive walls of glass. The hand-crafted organic architecture and landscape melds together offering an array of intimate spaces scaled for everyday living. Inspired to return to their agrarian roots, in 1972 the family purchased a 40 acre plot and planted over 900 avocado trees. Designed by the architect in 1984, the home of glass and wood with rock walls sourced from the surrounding property took 6 years to build. Nestled amongst the avocado grove, the home’s high perch lends itself to breathtaking 360 degree views of the area through the floor to ceiling windows. With 5 bedrooms and 3 bathrooms, as well as two fireplaces and custom woodwork throughout, this home captures some of Kellogg’s most inspired work, blurring the line between nature and home, between architecture and sculpture.
