Description
Set back from the road on 2.7 beautifully landscaped acres, 451 Mansfield Avenue offers the privacy, grandeur, and distinctive character of a true country estate. A sweeping circular drive introduces a grand residence distinguished by its striking stone facade and timeless architectural detailing, a substantial two-story guest house, and a magnificent outdoor setting centered around a 24' x 48' infinity-edge pool. Extensive custom stonework, elegant terraces, and lush grounds enhance the property's distinctive estate-like character. Extensively renovated in 2026, the residence features all- new mechanical systems, new windows, and thoughtfully redesigned interiors. Blending timeless architectural elegance with sophisticated contemporary luxury, the home offers approximately 9,000 square feet of finished living space, including a light-filled 1,600-square-foot walk-out lower level. Inside, a graceful, curved staircase rises from the herringbone-floored foyer, introducing beautifully proportioned rooms, distinctive millwork, and refined architectural detailing. Formal living and dining rooms, each with a custom marble fireplace, provide gracious entertaining spaces, while a richly paneled library with coffered ceiling and fireplace offers a distinguished private study.
