Old Brookville | Welcome to 3 Valentine Farm Court, where timeless architecture, exceptional craftsmanship, and an unmatched collection of luxury amenities define one of the North Shore's most impressive private estates.

Positioned behind double iron gates at the end of a secluded cul-de-sac, this stately brick center hall colonial is situated on more than three meticulously landscaped acres, combining remarkable privacy with an extraordinary level of recreation and entertaining amenities.

The residence is introduced by a spectacular two-story domed foyer showcasing a sparkling chandelier, intricate hand-painted ceiling details, and extensive custom millwork carried throughout every level of the home. Formal and informal living spaces are thoughtfully arranged, including an expansive formal living room, richly appointed mahogany library, inviting family room with one of three wood-burning fireplaces, formal dining room, powder room, and a spacious first-floor en-suite bedroom with separate exterior access.

The custom kitchen is appointed with premium gas appliances, custom cabinetry, a center island with seating, an adjoining breakfast area, and an expansive butler's pantry connecting directly to the formal dining room. Extending from the main level, an elevated terrace with a built-in outdoor kitchen overlooks the estate grounds and pool complex below.

The second level features five bedroom suites, each with their own full bathroom. Occupying its own wing of the home, the primary suite includes a private balcony overlooking the property, separate sitting room, two oversized walk-in closets, and an expansive en-suite bathroom with dual vanities and a jetted soaking tub.

Designed as an exceptional recreational and entertaining space, the lower level features a custom wet bar, expansive gathering areas, a fully equipped fitness center, additional bedroom and full bathroom, oversized laundry room, and a below-grade indoor sports court with min. 15-foot ceilings—a rarely available amenity in residential construction.

The outdoor amenities are equally impressive. The resort-inspired grounds are centered around an oversized gunite swimming pool with an integrated spa and water features, surrounded by expansive patios and mature landscaping. A fully equipped pool house includes a full bathroom, laundry facilities, and an indoor kitchen with a built-in grill opening directly onto the pool terrace. Completing the estate is a full-size sports court configured for both tennis and basketball, along with an oversized three-car garage equipped with vehicle lifts offering additional space for the car enthusiast.

Representing an exceptional combination of scale, craftsmanship, and amenities on more than three private acres, 3 Valentine Farm Court presents a rare opportunity within one of the North Shore's most distinguished settings.
