Introducing one of Tokeneke's most iconic waterfront estates-available for the first time in 50 years. This rare and storied compound is set on 2.4 acres of exquisitely landscaped grounds with 180 feet of private shoreline along Long Island Sound. It offers an unrivaled blend of historic charm, timeless elegance, and breathtaking coastal beauty. A sweeping two-story paneled foyer leads to a gracious formal living and dining rooms with soaring ceilings, fireplaces, and uninterrupted views of the water. Sunlight pours into the sophisticated sunroom-an ideal setting for quiet mornings or refined entertaining. The expansive kitchen and breakfast area open seamlessly to a family room with a granite fireplace, while a discreet back stairway leads to a stunning double-height billiards room with vaulted, beamed ceilings. The second floor is anchored by a grand primary suite with an oversized waterfront balcony, offering a private vantage point for sunsets over the Sound. Two additional bedrooms complete this level, with three more on the top floor to accommodate family or guests in style. A separate three-car garage includes a fully finished upper level with a full bath-ideal for a guest suite, gym, or private office. This exceptional estate embodies the quiet prestige of a bygone era, offering privacy, beauty, and unparalleled access to the water-all in the heart of Darien's most coveted private enclave. A once-in-a-generation opportunity to own a true coastal masterpiece.
