    What's special

    Known as River House, this newly completed riverfront estate of international distinction is elevated atop a commanding 30 foot bluff in Sewalls Point, spanning 4.3 acres and capturing sweeping, mile long sunset views across the St. Lucie River.Conceived as a modern Bahamian retreat, the residence blends imported Belgian modern materials with warmth, restraint, and timeless elegance. The architecture unfolds as a series of distinct pavilions in stone, oak, and plaster, thoughtfully positioned to embrace the land, the river, and effortless everyday living. The home has been internationally recognized and featured in Vogue Australia for its refined design and craftsmanship. Curated by Melhorn Architecture & Construction with interiors by Design Studio JAC, the estate reflects a level of intention and craftsmanship rarely achieved, resulting in a residence designed for longevity rather than trends. Dominican coral flooring, creamy lime plaster walls with Roman clay texture, and expansive walls of glass create a calm, gallery like backdrop for art and waterfront vistas. Vaulted ceilings accented by reclaimed European oak beams lend depth and permanence, while subtle variations in tone and texture define an atmosphere of quiet luxury. Outdoor living is seamlessly integrated through impact glass wall systems, with a resort style pool, expansive deck spaces, and lush gardens extending the living areas into the landscape and down toward a private beach. Mature oak and banyan trees frame the setting, reinforcing the estate's sense of privacy, scale, and serenity. A world class boating compound offers deep water dockage with multiple lifts, accommodating vessels over 100 feet with ease while providing direct access to the inlet and open ocean. The estate is further complemented by a private guest house, three garages with capacity for up to 17 vehicles, and meticulously designed grounds. Thoughtfully curated from architecture to landscape, River House represents a generational waterfront offering. Timeless in design, rich in detail, and among the most distinguished estates in South Florida.
