About This Home

With 100 feet of private Atlantic frontage and nearly a half-acre of manicured beachside grounds, 3717 South Ocean Boulevard is a modern oceanfront estate designed for life on the water. Built in 2015 of concrete construction across three stories, the residence delivers approximately 12,000 square feet of living area where expansive terraces, an infinity-edge pool and spa, and multiple observation points put the ocean at center stage.

Architectural intentions are clear from the moment you arrive via the private driveway: generous scale, clean contemporary lines and durable seaside materials. Inside, the home was conceived for entertainment and family living — a gourmet kitchen and multiple gathering rooms open to broad terraces, a dedicated home theater and an elevator servicing every level. Seven bedrooms and seven-and-a-half baths accommodate multigenerational stays or a full roster of guests with privacy and comfort.

Outdoor spaces maximize the beachfront setting. The infinity pool and adjacent spa sit steps from the sand, terraces span the seaward façade for uninterrupted viewing, and private beach access makes the Atlantic a daily amenity. A six-car attached garage plus additional driveway parking support recreational toys and visiting guests.

Practical systems and construction reflect coastal priorities: central heating and cooling, a flat roof designed for the site, and reinforced concrete walls. The estate presents a rare combination of large scale, modern construction and direct ocean frontage in Highland Beach — positioned minutes from Delray Beach and Boca Raton for dining, shopping and club amenities while remaining a private, secure seaside retreat.

This property is offered with a thoughtful valuation range informed by nearby oceanfront estate sales. For buyers seeking a primary or second residence with uncompromised ocean access and significant entertaining capability, 3717 South Ocean Boulevard stands out as one of the finest available oceanfront estates in the area.

Neighborhood

Highland Beach is a compact, affluent barrier island community defined by private beachfront living and high-quality single-family estates. Residents enjoy quiet streets, limited commercial intrusion and fast access to upscale dining, shopping and club life in nearby Delray Beach and Boca Raton. The one-mile population is small with strong household incomes, making the town an attractive enclave for buyers who value privacy but want cultural and recreational amenities within a short drive. Private schools and established country and beach clubs are convenient for families and second-home buyers.

Market Insights

The Highland Beach oceanfront market currently favors sellers within the ultra-luxury submarket due to extremely limited inventory of true oceanfront estates. Recent comparable closings on the same block illustrate the range you can expect: 3715 S. Ocean Blvd closed at $43.85M in 2025, 3719 S. Ocean Blvd closed at $22.5M in 2024, and a slightly older oceanfront estate at 4217 S. Ocean Blvd sold for $15M in 2025. Those transactions, combined with broader area metrics — roughly six months of inventory and an average days-on-market near 90 — indicate steady demand and selective supply.

Median area sale price across the wider market sits near $5M, but Highland Beach oceanfront product commands a significant premium. One-year appreciation stands near 5% and five-year appreciation around 25%, supporting the valuation estimate of $28M–$32M for this asset. Buyers should note elevated annual property taxes (approximately $500,000) and coastal exposure considerations, while sellers can capitalize on strong buyer interest for rare, turnkey oceanfront estates. For investors and owner-users alike, current conditions reward well-priced, well-presented listings in this corridor.
