Extraordinary, one-of-a-kind private estate commanding a majestic hilltop position on 9.5 sprawling acres of broad lawns, mature woods, and breathtaking western sunsets. Serving as the anchor of Rocky Ridge Lane—an exclusive new four-lot private enclave situated near the prestigious Dedham Country & Polo Club—this rare property seamlessly blends tranquil privacy with ultimate geographic convenience. Built in 2000, the architect-designed main house exudes the classic elegance and sophistication of a European country house. Principal rooms boast high ceilings, impeccable attention to detail, and an abundance of natural light streaming through a series of French doors that open to a stunning west-facing stone and brick terrace. The generous spaces are perfectly tailored for both grand and casual entertaining, having recently been beautifully renovated and reconfigured to yield additional informal living spaces. Newly renovated kitchen with island bar and sitting area opens onto dining area and family room with bar. Main-level living is made effortless by a luxurious first-floor primary suite, which captures serene views of the outdoor fountain and the property’s defining historic feature. Steeped in history, the property which once was the Capen Farm, then the site of the clubhouse of Dedham Country Club, includes the “Castle,” a spectacular c.1930 stone and slate 1,400-square-foot fairy-tale outbuilding. Designed by renowned architect Henry Richardson Shepley, it features a striking crenelated tower and was originally built to house and protect its owner’s important collection of books and manuscripts. The magnificent library’s original casework and paneling have recently been painstakingly restored to their former beauty and luster. Featuring its own kitchenette and 3/4 bath, this one-of-a-kind sanctuary, complete with hidden doors, spiral staircase, and lofted garret room offers endless potential to be reimagined as the ultimate home professional office, artist or writer’s studio, wunderkammer, music room, collector’s display, masculine retreat, or ADU. While offering a peaceful and secluded country-like sanctuary, this exceptional home enjoys unparalleled proximity to Dedham, Westwood, and Needham town centers. It provides easy access to Route 128/95, top-tier private schools, multiple commuter rail options, Legacy Place, and Westwood Station, striking the perfect balance between timeless luxury and convenient accessibility. Showings begin Sept. 1.
