This stunning English Tudor Revival estate embodies timeless elegance in every detail from the arched-molding formal entry doorway to the many Tudor casement windows overlooking the garden retreat with mountain views. The six-bedroom, eight-bathroom residence, designed by celebrated architect Edward Ullrich, has been meticulously renovated and updated to reflect modern sophistication while preserving its remarkable architectural heritage. Most all home features and systems were completely updated and restored in 2017, including refinished white oak floors, re-chromed Crane bathroom fixtures, restored coffered ceilings, and beautifully renovated leaded glass windows. The chef’s kitchen was fully renovated in 2017 with custom cabinets and island, marble countertops, and JennAir Professional appliances, also newer central HVAC and ductwork, copper plumbing and main sewer line, updated electrical panels, all ensuring peace of mind. In the backyard, an enchanting oasis awaits. The impressive sunroom opens to the salt-water lap pool and jacuzzi, offering a serene retreat, while the exquisite guest house, with fabulous redwood paneling, the vaulted ceiling with the rustic beams, provides the perfect space for entertaining and visitors. This estate is a true masterpiece, seamlessly blending historical charm with contemporary luxury. Situated on a half-acre in the coveted San Marino area near the Huntington Library and Caltech, the masterful architectural craftsmanship and aesthetic characteristics make 830 Chester a piece of art, and a cozy home.
