An extraordinary opportunity to own a legacy estate set on over an acre of artfully landscaped grounds, just one mile from Harvard. Here, the gardens transform with the seasons, offering an ever-changing tapestry of color, texture, and botanical variety. This remarkable property offers a rare combination of privacy, luxury, and timeless beauty in one of the area’s most sought-after locations.

The stately main residence features 7 bedrooms, 6 full bathrooms, and 2 half baths—thoughtfully designed to accommodate both grand-scale entertaining and comfortable daily living. Wrapped in an 80-foot porch, the home overlooks a heated swimming pool, meandering stone pathways, and vibrant seasonal gardens. The gently sloping grounds evoke the feel of a private arboretum, complete with a tranquil koi pond, luxurious spa, whimsical outbuildings, and a variety of pergolas, patios, and secluded garden retreats.

Inside, tall windows, soaring ceilings, and a dramatic staircase create a sense of grandeur, while multiple fireplaces lend warmth and character throughout. Expansive and flexible living areas offer endless possibilities for modern living.

Upstairs, a private au pair suite provides added comfort and privacy. A separate, two-level guest apartment above the garage includes a spacious bedroom suite, kitchen, and open living/dining area—ideal for extended family or guests.

This is more than a home—it's a rare and refined retreat in an exceptional location.
