A rare opportunity to own one of Sea Island's most significant waterfront estates. Perfectly positioned along a protected deepwater inlet with sweeping southwestern sunset views, Cottage 522 offers an extraordinary combination of scale, craftsmanship, and setting within one of the East Coast's most exclusive communities. Spanning more than 17,000 square feet, the residence was conceived for generations of ownership and thoughtfully designed for both grand entertaining and everyday living. Following an extensive renovation completed in 2023, the home presents a timeless collection of living spaces where architectural character and enduring materials take center stage. Marble and hardwood floors, tumbled stone walls, custom detailing, and nine fireplaces create a sense of warmth, permanence, and understated elegance throughout. The residence unfolds through a series of expansive gathering spaces, private retreats, and beautifully appointed guest accommodations. Oversized windows and glass doors frame panoramic marsh and water views while inviting natural light into every room. A gourmet chef's kitchen anchors the home, complemented by multiple formal and informal living areas designed to accommodate family and guests with ease. Outdoor living is equally compelling. A newly constructed deepwater dock provides direct access to coastal waters, while the expansive pool, pool terrace, and waterfront entertaining areas create an exceptional setting for relaxation and entertaining. The estate's protected waterfront location offers a rare balance of privacy, tranquility, and connection to the surrounding natural beauty. Built with solid concrete block construction and pilings extending more than fifty feet below grade, the home reflects a level of structural integrity and craftsmanship rarely found today. Every element was designed with longevity in mind, creating a residence that is as enduring as it is impressive. Located within the Sea Island community, ownership includes the opportunity to apply for membership to the Sea Island Club, offering access to championship golf, private beach facilities, fine dining, and world-class amenities. Rarely does a property combine this level of waterfront frontage, scale, construction quality, and location. Cottage 522 represents an exceptional legacy estate and one of the finest deepwater offerings on Sea Island. Furnishings may be negotiated separately through a bill of sale outside of closing.
