Historic Pennsylvania stone farmhouse meets modern sustainability, tucked between picturesque Bucks and Northampton Counties and at the base of the Lehigh Valley. Bog Turtle Farm is a rare fusion of history, nature, and convenience. Set on over 24 acres of woodlands, historic stone walls, and a meandering stream, this property offers a true sanctuary—one that has even provided a habitat for the bog turtle. The heart of the home is a beautifully preserved historic residence featuring original exposed beams, wide-plank wood floors, and thoughtful updates that honor its past. On the first floor, the updated kitchen is both stylish and functional, boasting newer appliances, a center island, walk-in pantry, and your first glimpse of Mercer tile embellishment on the farmhouse sink. The kitchen and dining room, with large stone fireplace and mantel, connect you to a cozy den with a wood stove, slate floors, and stone walls. A small office, powder room, two living spaces with endless possibilities, and access to indoor/outdoor kennels, round out the first floor. The second floor is a retreat of its own, featuring a considerable primary suite with sitting areas, a walk-in closet, and spa-like en suite complete with a jetted tub, walk-in shower, and double vanity. An additional bedroom, hall bath with claw foot tub and pedestal sink, and a laundry room complete the second floor. A wood staircase takes you to the 3rd floor where a small bedroom exudes historic charm. Outside, the grounds are nothing short of breathtaking. A sparkling pool with a water feature, surrounded by an elegant stone patio and charming gazebo, invites warm summer gatherings. A stunning historic barn has hosted a wedding, parties, and concerts and includes a two-bay garage and separate workshop. Attached dog kennels and a stable with infinite potential make this property ideal for animal lovers, hobby farmers, or equestrian pursuits. Sustainability meets sophistication with the home's geothermal heating system, providing year-round efficiency and comfort. A generator ensures peace of mind, while the property’s remarkable privacy yet seamless connectivity makes it the perfect retreat for remote work. And despite its secluded feel, this farm offers an easy commute to both New York City and Philadelphia, making it a rare gem balancing tranquility with accessibility. Whether you're seeking a working farm, a creative retreat, or a private escape in nature, this one-of-a-kind property delivers an unparalleled lifestyle—where history, sustainability, and natural beauty come together in perfect harmony. Welcome Home.
