Description

A rare opportunity to own a distinguished piece of Mendham Township history. Originally built in 1830 and thoughtfully expanded over time, this exceptional Colonial is privately set on approximately 3 picturesque acres, seamlessly blending historic charm with modern luxury. Designed for both grand entertaining and everyday living, the home offers expansive gathering spaces, including an oversized great room and an elegant living room anchored by a wood-burning fireplace and adjoining library. The gourmet kitchen is appointed with a striking Ferrari Red Bertazzoni 5-burner gas range and hood, 42-inch Viking side-by-side refrigerator, Bosch dishwasher, and a handcrafted English country island, with direct access to a covered patio overlooking the serene grounds. A remarkable two-story barn, constructed in 1980 with reclaimed hand-hewn beams to reflect the home's original character, offers endless possibilities for entertaining, a studio, fitness space, home office, collector car storage, workshop, or more. Upstairs, the luxurious primary suite features a spa-inspired bath with soaking tub, separate shower, and dual vanity, complemented by three additional bedrooms. (Septic is being upgraded from 3 bedroom to 4 bedroom before closing.) A truly timeless country estate where history, craftsmanship, and modern comfort come together.
