Welcome to 3 College Ave, an exquisite estate manor home in the heart of the Main Line. Originally a model home, this residence showcases unparalleled craftsmanship and attention to detail. Built by Manchester Hall Builders with renowned Lancaster County craftsmen. Meticulously maintained or upgraded by local family-owned businesses, this home remains in showcase condition. Entrance piers and estate fencing greet you as you approach the property. Positioned well back from the road, the home is screened by mature trees for complete privacy. A front motor court offers abundant parking. Entering through the marble-floored foyer, you are greeted by a grand front-to-rear center hall. The living room, with its coffered ceiling and gas fireplace, provides an inviting retreat. The dining room features two ceiling medallions and decorative moldings, served by a butler's pantry with a second dishwasher and beverage fridge. French doors from the center hall lead to a covered terrace with a built-in gas grill and fire pit, ideal for summer BBQs and fall gatherings. Extensive outdoor living spaces ensure enjoyment of the beautiful surroundings in every season. The spacious gourmet kitchen is a culinary dream. Appointed with a triple-tiered center island, granite countertops, double Thermador wall ovens, Sub-Zero refrigerator, and Thermador cooktop, the kitchen is both beautiful and functional. A large walk-in pantry offers ample storage. The breakfast room, featuring a vaulted ceiling and 3 walls of large windows, is bathed in natural sunlight. Adjacent to the kitchen, the family room boasts a coffered ceiling with patterned tin ceiling tiles. A fireplace with a floor-to-ceiling stone surround serves as the room's focal point, flanked by custom built-in cabinetry. The room also features a custom built-in wet bar. Glass-paneled doors open into the sunroom, seamlessly connecting the two spaces. The sunroom, with a gas fireplace, radiant heated slate flooring, and wood ceiling, also opens onto the covered terrace. Two conveniently located powder rooms provide easy access. Additional features on the first floor include a cherry-paneled home office/library with built-in bookcase and a gas fireplace, a workstation command center, and a mudroom leading to a heated and air-conditioned three-car garage with a dog shower.
