A once-in-a-generation opportunity to own one of the most extraordinary oceanfront estates on Sea Island. LoweTide is a masterwork of global artisanship, architectural pedigree, and bespoke execution. Custom-built in 2021, the home reflects a deeply personal vision realized with uncompromising attention to quality, craftsmanship, and enduring design. Spanning over 11,000 square feet, the residence unfolds as a series of refined living environments where scale, proportion, and materiality are meticulously considered. Interiors evoke a distinguished European private estate, featuring hand-carved moldings by J.P. Weaver, museum-quality St. Louis crystal lighting, custom hardware by P.E. Guerin, and bespoke cabinetry by Clive Christian. The primary kitchen is anchored by a La Cornue range and complemented by a professional-grade chef’s kitchen by Officine Gullo, custom-built on site with walk-in refrigeration, dedicated prep areas, and an adjacent chef’s office. Formal and informal spaces transition seamlessly—from a Parisian-inspired dining room beneath a skylight to a richly paneled library and bar. The primary suite serves as a private sanctuary with dual studies, bespoke dressing rooms, and marble-clad baths. Guest accommodations offer ensuite privacy throughout, including a third-floor suite with elevator access. A rooftop terrace captures sweeping Atlantic views, while loggias, a solarium, and ocean-facing living spaces maximize natural light and horizon lines. Outdoor living is equally exceptional, featuring a signature quatrefoil pool, pergola, and climate-controlled covered loggia with retractable screens and heated flooring. Multiple garden and fountain settings create a resort-like sense of privacy and serenity, while seamless indoor-outdoor flow accommodates entertaining on any scale. Additional features include a four-car garage with lift capability, staff quarters, fully integrated back-of-house operations, and state-of-the-art infrastructure throughout. Crafted with hand-selected Italian marble, custom parquet flooring by Foglie d’Oro, limestone elements, and the work of heritage artisans, LoweTide stands as a rare expression of refined coastal living in one of the East Coast’s most exclusive enclaves.
