Property Description

Known as River House, offered fully furnished & turnkey (excluding artwork), this newly completed riverfront estate sits atop a commanding 30-foot bluff in Sewalls Point, spanning 4.3 acres with sweeping, mile-long sunset views across the St. Lucie River. Designed as a modern Bahamian retreat, the residence blends imported Belgian materials with warmth and timeless elegance. Internationally recognized and featured in Vogue Australia for its exceptional design and craftsmanship. Complementing the offering, bespoke Seller Financing is available, including up to one-third of the purchase price, structured as interest-only for a period of up to five years, with no prepayment penalty, an uncommon and highly advantageous provision designed to accommodate a variety of acquisition strategies. 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.
