Nestled in one of San Marino's distinguished neighborhoods, this grand Tudor Revival estate offers timeless architecture, exceptional scale, and an outstanding opportunity to reimagine and update a classic residence to today's modern standards. A long private driveway and mature landscaping create an elegant storybook presence. The impressive entry opens to a dramatic two-story foyer highlighted by a sweeping wood staircase and soaring ceilings. The gracious sunken living room features a fireplace, oversized bay windows, and abundant natural light, while the formal step-down dining room is ideal for entertaining beneath a sparkling chandelier. The expansive gourmet kitchen includes a large center island, rich oak cabinetry, dual cooktops, double ovens, a built-in Sub-Zero refrigerator, and a sunny breakfast area. Adjacent, the bright family room showcases extensive built-ins, an entertainment center, a fireplace, and French doors opening to the backyard. A convenient downstairs bedroom, full bathroom, and laundry area complete the main level. Upstairs, the spacious primary suite offers a private retreat area, cozy fireplace, and walk-in closets. The primary bathroom features dual vanities, a Jacuzzi, and a separate shower. Two additional en-suite bedrooms, one generously sized secondary bedroom with an additional bathroom, and a large den - ideal for a home office, gym, game room, or potential additional bedroom - complete the upper level. The beautifully landscaped backyard is designed for both relaxation and entertaining, featuring a sparkling pool, spa, and mature greenery. Additional highlights include a three-car attached garage with extensive storage, dual HVAC systems, LED recessed lighting, Andersen windows and doors, and fresh interior and exterior paint. While the home has been well maintained, it presents an exceptional opportunity for customization and updating, allowing the next owner to transform this classic 1989-built estate into a truly spectacular modern residence.
