One of Desert Knolls' earliest architectural estates, this 1948 adobe ranch was designed by noted Southern California architect John Byers, whose work helped define early California and Spanish-Revival residential design. Built with 12-inch handmade adobe block and classic Byers detailing, the home carries an authenticity and craftsmanship rarely found today. Signature elements include open-beam ceilings, extensive built-ins, hardwood floors, and a dramatic floor-to-ceiling fireplace constructed from salvaged Tehachapi earthquake brick.The single-level layout spans over 3,000 sq ft with a large great room, formal dining room, breakfast nook, family room with fireplace, and a finished basement with wet bar ideal for hobby, creative, or entertainment use. Updates complement the home's architectural integrity, including refreshed flooring, upgraded kitchen surfaces and appliances, improved paint, and enhanced bath fixtures.Set on a private 1.85-acre lot with mature trees, a detached garage, gated parking, pool and spa, a separate casita with its own bath, and paid-off solar for energy efficiency. A rare chance to own an authentic John Byers adobe estate with land, character, and architectural pedigree.
