Timeless Architectural Gem On Expansive Private Acres

Set within Bernardsville’s highly coveted “On the Mountain” enclave, this extraordinary residence is a rare offering steeped in architectural history and timeless charm. Originally the carriage house of famed nineteenth and twentieth century architect George B. Post Sr.’s estate, this expanded and thoughtfully converted 1890s structure rests on five point twenty-five private acres, accessed by a long, winding driveway that immediately sets the tone for serenity and seclusion.

History echoes throughout the home, where original stonework, century-old trees, and established plantings create a rich sense of place. It beautifully balances traditional authenticity with modern elegance, offering warmth, character, and charm at every turn.

At the heart of the home is a dramatic sunken living room, showcasing original stone details and offering an inviting space for both grand entertaining and quiet reflection. With over five thousand square feet of living space, including a substantial addition completed in 2000, the home features five bedrooms and five full bathrooms, including a private nanny or guest suite with its own bathroom.

Outdoor living is equally compelling, with fall and winter views of the Somerset Hills, an in-ground pool, and expansive grounds designed for privacy and tranquility. Car enthusiasts will appreciate the eight total garage spaces, including two detached garages—a truly rare amenity.

Located just minutes from the New Jersey Transit rail station, shopping and the Somerset Hills Country Club, this one-of-a-kind property rewards its next owner with a remarkable lifestyle where architectural pedigree, natural beauty, and peaceful living converge.

A pursuit of tranquility. A legacy property. A rare opportunity.
