This gracious shingled estate, known as Sierra Bonita Ranch - Yerxa House, is situated on a gated and lushly landscaped .92 acre lot and was completely reconstructed in recent years from exterior walls to interior studs while retaining its original exterior design. As a Designated Historical Landmark and under the Mills Act, thus enjoying substantially reduced property taxes, the nearly 6800 square foot home offers mountain and valley views, expansive public rooms, and wide terraces for large-scale entertaining.   No detail was overlooked in the years' long reconstruction of the home and grounds with meticulous attention to detail and superior craftsmanship, including elegant finishes with box beams and crown mouldings, sophisticated lighting throughout, and new electrical, plumbing, whole house water filtration, water softener, fire sprinkler and solar systems, built-in window screens, seismic retrofitting, exterior walls, shingles, roof, and terrace.  Special interior features include fireplaces in the Living and Dining Rooms as well as the Primary Bedroom suite, multiple French doors opening to terraces and decks, a Lacanche stove, two Miele dishwashers and wine refrigeration in the Kitchen, an office, theater and sun rooms, and a magnificent second floor Library-Family Room. Exterior features include pool, spa, new landscaping, lighting, and stonework, a porte-cochere, and sweeping front and rear lawns. This is an exceptional estate offering of a truly 'newer old house' in the heart of one of the San Gabriel Valley's most beloved village communities
