About this home
2410 HARBOURSIDE DRIVE UNIT 142
Positioned on the fourth floor of Marina Bay Building I, this fully renovated bayfront residence offers sweeping views across Sarasota Bay and the Harbourside Golf Course from one of Longboat Key’s most exclusive gated communities. Encompassing more than 3,300 square feet of interior living space, this three-bedroom, three-and-a-half-bath residence blends the scale and privacy of a single-family home with the convenience of condominium living. From the moment you enter, walls of floor-to-ceiling glass sliders and oversized windows frame panoramic water and golf course vistas while filling the home with natural light. The open great-room layout creates a comfortable flow between the living, dining, and entertaining spaces, enhanced by engineered hardwood flooring, crown molding, custom built-ins, tray ceilings, and thoughtfully designed lighting. The chef’s kitchen was completely redesigned in 2024, showcasing custom shaker-style cabinetry, quartzite countertops, and an extended island finished in complementary natural wood. High-end appliances include a Viking induction range, Miele built-in coffee station, wine refrigerator, and reverse-osmosis filtration system. A tile backsplash, pantry storage, and built-in planning desk complete this functional and beautifully designed culinary space. The kitchen connects seamlessly to the casual dining area and adjacent media room, creating an ideal setting for everyday living and entertaining. Additional improvements include two new HVAC systems installed in 2025 and remote-controlled storm shutters on all waterfront openings installed in 2024, offering comfort, efficiency, and peace of mind. The primary suite serves as a private waterfront retreat with direct terrace access and serene bay views. Renovated in 2024, this spacious suite features dual walk-in closets with built-in storage systems, and an updated en-suite bath offering dual vanities, soaking tub, and glass-enclosed shower. Two additional guest suites are positioned on the west side of the residence in a split layout, each with walk-in closets, en-suite baths, and access to a shared terrace for visiting family and guests. Secure under-building parking and elevator access add everyday convenience. Marina Bay is an intimate waterfront community of only 60 residences, located behind the gates of Bay Isles. Residents enjoy 24-hour guard-gated security, on-site management, a fitness center, tennis courts, grilling area, and a heated bayfront swimming pool and spa with a scenic sundeck. Ownership also includes deeded access to the private Bay Isles Beach Club, where residents enjoy Gulf-front pavilions, gated parking, and direct access to the white-sand beaches of Longboat Key. Ideally located on the south end of the island, Marina Bay is just minutes from Harbourside Golf Course, the Longboat Key Club marina, and waterfront dining. St. Armands Circle offers boutique shopping and restaurants nearby, while downtown Sarasota’s theaters, galleries, and cultural venues are only a short drive away. From boating and golf to sunset walks along the Gulf, this residence places the best of Longboat Key and Sarasota living within easy reach.

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.
