Welcome to this truly unique property, rich with history and character. Built in 1908 and constructed of Roman cobbles, the former Caswell Library has been thoughtfully transformed into a one-of-a-kind residence while preserving its original charm. The standout feature is the stunning semi-circle library room on the main floor, offering a bright and welcoming space for relaxing with a book or gathering. A lovely round sitting/eating nook, full of natural light, complements the spacious living room, dining room, kitchen, and convenient half bath. Located right on Main Street in the heart of Harrison, this home offers a prime location, just a short 2-minute walk to Long Lake public beach and boat launch. You'll love the convenience of being close to local stores, restaurants, and nearby towns like Waterford, Norway, and Bridgton. A brook runs through the backyard, adding a touch of nature to this central location. Downstairs, there are two bedrooms, an office/closet space, a full bathroom, and a laundry area, blending historical architecture with modern living. With its unique design and prime location, this property offers incredible potential—not only as a charming residence but also as a business or office space.
