Overview

Welcome to 148 Liberty Street - the Joseph Firman House—an exquisite example of Victorian Gothic architecture tucked into one of Newtown Borough’s most historic and picturesque blocks. Built circa 1860 by noted builder and landowner Joseph Firman , this 4-bedroom, 2.5-bath residence offers a rare blend of preserved 19th-century character and thoughtful modern upgrades. From the double pointed-arch windows and steep gabled roof to the deep eaves and delicate gable pendants, this home is a standout in local architectural history. Inside, you'll find a large living room and dining room, original wide-plank wood floors, charming millwork, and fireplace. The family room is a wonderful gathering space and flows into a modern kitchen with a large center island, and a bright breakfast room addition overlooking a peaceful brick patio and garden. The second floor offers three bedrooms including a hall bath and an expanded primary suite, while the third floor provides a versatile retreat—a perfect 4th bedroom and playroom, studio, or bonus guest space. Outside, enjoy a beautifully landscaped and very private back yard. The detached garage/barn has a second floor for hobbies, gym space, or storage. All of this just steps from boutique shopping, award-winning restaurants and pubs, cozy coffee shops, playgrounds, and Tyler State Park. Located in the Council Rock North School District and only minutes from major commuter routes to Philadelphia, New York, and the Princeton Corridor, this home is not just a piece of history—it’s a lifestyle. Whether it's cozy nights curled up by the fire, a lazy afternoon on the front porch or balmy summer barbeques on the patio, this home offers it all. Welcome to 148 Liberty St... Maybe you are home already!
