About this home

500 HARBOR COVE CIRCLE

Under Construction. Now nearing completion and expected to be delivered in approximately 60 days. Positioned within the exclusive Harbor Section of Bay Isles on Longboat Key, 500 Harbor Cove Circle is a newly constructed waterfront estate offering a rare combination of exceptional boating access, modern architecture, resort-inspired living, and one of the Gulf Coast’s most coveted addresses. Located behind the double gates of Bay Isles and directly across from The St. Regis Longboat Key Resort, residents enjoy immediate proximity to world-class hospitality, fine dining, marina services, championship golf, and tennis, while ownership includes access to the Bay Isles Beach Club. Encompassing 5,120 square feet under air and 8,564 square feet total, the residence features 5 bedrooms, 5 full baths, 1 half bath, a private office, elevator access to all levels, and a 4-car garage. A fully integrated smart home automation system provides seamless control of lighting, climate, security, audio, window treatments, pool and spa functions, and key home systems throughout the property. The arrival experience unfolds through a lagoon-inspired reflecting pool, floating stairway, and lush tropical landscaping, creating a dramatic resort-style arrival. Architectural lighting, natural stone, warm wood accents, and expansive walls of glass establish a sophisticated coastal aesthetic throughout the residence. Inside, expansive living spaces are enhanced by Venetian plaster, custom millwork, large-format stone surfaces, and carefully curated architectural details. One of the home’s defining architectural statements is a dramatic 20+ foot monolithic travertine feature wall wrapping an entire corner of the residence, creating a striking design element rarely found in residential construction. The chef’s kitchen is anchored by an oversized Calacatta marble waterfall island, premium custom cabinetry, integrated appliances, and generous entertaining space. Designed for seamless indoor-outdoor living, the residence opens to expansive covered terraces, a resort-style pool and spa, and a fully equipped outdoor kitchen featuring a grill, pizza oven, refrigeration, and multiple gathering spaces. Wellness-focused amenities include a private fitness area, sauna, cold plunge, and dedicated spaces for relaxation and recovery, creating a private wellness retreat. For boating enthusiasts, the property offers approximately 100 feet of protected waterfront frontage with direct access to Sarasota Bay and the Gulf of Mexico in less than two minutes. The dock is designed to accommodate a substantial yacht while still providing room for multiple additional lifts for a tender, fishing boat, personal watercraft, and other recreational vessels—an increasingly rare offering among Florida’s premier waterfront estates. One of the Gulf Coast’s rare opportunities to enjoy new construction, large-yacht capability, and resort-inspired living within the exclusive Harbor Section of Bay Isles.

Value check

Is the price right?

The internet’s favorite home-value number comes from a single automated model that has never seen the street, the finishes, or the view — which is why it routinely misses by tens of thousands of dollars. The edgeAI estimate combines multiple independent data sources with our team’s on-the-ground expertise in this exact market.
