A Timeless Masterpiece. Commissioned in 1932 by Stella May Preble Nau of the pioneering Preble family of Tustin, this residence is a rare piece of living history and an architectural jewel that carries the craftsmanship and spirit of another era. Relocated to its current level lot in 1972, the estate blends period authenticity with thoughtful modern comforts. Nearly everything remains original in the most nostalgic way. Hardwood floors, never refinished, tell a century's story. Mahogany cabinetry, leaded glass pocket doors, light fixtures, copper downspouts, and detail shutters have all been lovingly preserved. Authentic Eastlake hardware graces doors throughout, with its distinctive geometric style. The interiors, rich with character, include French doors, exposed beams, statement fireplaces, ornate air grates, and dual glass pocket doors. Coffered ceilings with mahogany inlays and a plaster medallion crown the formal dining room. The library offers walnut cabinetry and an original roll top desk. Thoughtfully modernized yet infused with old-world charm, the kitchen features granite counters, Viking range, dual ovens, two Thermador dishwashers, warming drawer, large island, and butler's pantry with swinging door. The original main floor primary suite now serves as a family room with arched French doors opening to the pool courtyard. Wedded in history, the staircase and chandelier usher residents to the upper chambers. 4 bedrooms include one with a cedar-lined walk-in closet, another once a sewing room (complete with built-in iron rest and pull out board), and a light filled suite with dressing room, shoe drawers, and balcony. A private staff quarter has been reimagined as a guest retreat with laundry. Rare for the period, a basement offers mechanicals and generous storage. Outdoors, the estate shines with a saltwater pool shaded by a Japanese maple, a lush yard featuring a hidden treehouse, chicken coop, and an entertainer's terrace with flagstone and outdoor fireplace. Mature trees, some dating to the 1970s relocation, include fruit, heritage boysenberries, melaleuca trees, sycamores, and king palms. The three-car garage provides epoxy floors, storage, and a workbench by Premier Garage. A true blend of historic authenticity and modern livability, this 1930s treasure is a piece of Tustin's heritage ready for its next chapter.
