Harbor views abound from this beautifully renovated and impeccably maintained Waterfront Colonial, perfectly suited for both grand entertaining and intimate gatherings. The expansive wraparound rear terraces provide an exceptional setting for outdoor living and are the perfect place to gather and enjoy the spectacular Fourth of July fireworks. For boating enthusiasts, the property offers a deep-water dock just minutes from the harbor entrance to Long Island Sound. Summer living is made even more enjoyable with the home’s proximity to the SAPC, offering access to the pool at the water’s edge and the clubhouse—a wonderful opportunity to relax, socialize, and get to know your neighbors. Inside, the home welcomes you with a gracious entry hall and an expansive living room featuring a fireplace. The living room flows seamlessly into a handsome wood-paneled library, with French doors opening to one of the rear terraces. Throughout these main living spaces, 8'9" ceilings enhance the sense of light and volume. The living room also leads to the charming enclosed “On Golden Pond” porch, an inviting retreat in three seasons. The formal dining room opens directly to another terrace, while the butler’s pantry provides a seamless transition to the generously sized kitchen, renovated in 2019. A substantial island with bar seating anchors the space and separates the dining area from a cozy sitting area with a gas fireplace and TV. The kitchen also opens onto a large covered porch, creating an ideal space for relaxed dining and entertaining regardless of the weather. Upstairs, the primary suite features an en suite bath and French doors leading to a private balcony overlooking Mamaroneck Harbor. The hallway continues to three additional bedrooms and a hall bath, as well as a second primary suite with its own en suite bath and a fabulous private deck offering sweeping harbor views. With its exceptional waterfront setting, deep-water dock, multiple outdoor entertaining spaces, and beautifully updated interiors, this is a truly special home designed for enjoying the very best of waterfront living.
