Originally built in 1880 as part of the 200-acre Mott family farm, 6B Blue Sea Lane originally named ‘Gracefield’, was transformed into a stately Federal-style mansion in 1909 by renowned architect James W. O’Connor for William Russell Grace, former New York City mayor and founder of W.R. Grace & Co. Meticulously restored to its original splendor, this architectural masterpiece now blends historic elegance with modern luxury.
Set on over two acres of impeccably manicured grounds within the esteemed Village of Kings Point, the estate is accessed via a private road and a dramatic tree-lined 450-foot driveway. Offering breathtaking views of the Long Island Sound and offers exclusive dock rights, the property provides unmatched privacy and coastal glamour.
Inside, the grand entry foyer introduces a world of refined living. Period details abound - from original woodwork, intricate fireplace mantels and antique hardware to soaring ceilings and gracious bay windows. The expansive interior includes a formal ballroom, richly paneled library, elegant oversized living and dining rooms, and a state-of-the-art gourmet kitchen that opens into an inviting family room.
The second level features a luxurious primary suite with walk-in closets and a private balcony overlooking the water, along with four additional en-suite bedrooms, a spacious den, a laundry room, and a separate two-bedroom guest apartment with a private entrance. The third floor offers incredible flexibility with additional bedrooms and baths, a large playroom/flex space, fitness room, and ample storage.
Outdoors, enjoy a heated pool and cabana, surrounded by sweeping lawns and lush landscaping that echo the estate’s everlasting sophistication. A prestigious courtyard driveway, multiple storybook covered patios and terraces, radiant heated floors, and a 3-car attached garage complete this extraordinary offering.
Totaling eight bedrooms, ten bathrooms, 20,000+/- Sq.Ft. and panoramic water views, 6B Blue Sea Lane is a rare opportunity to own a piece of North Shore history - where timeless heritage meets refined living.
