Marina Bay

Located behind the gates of Bay Isles on the southern end of Longboat Key, Marina Bay is an intimate bayfront condominium community consisting of 60 residences within three mid-rise buildings. Spacious floor-through residences, screened terraces overlooking Sarasota Bay, western balconies, on-site management, and a central collection of recreational amenities create a private residential setting with the convenience of condominium living. Ownership also includes membership in the Bay Isles Association and access to the private Bay Isles Beach Club on the Gulf of Mexico. Combined with 24-hour guard-gated security and proximity to the Longboat Key Club marina, Harbourside Golf Course, St. Armands Circle, and downtown Sarasota, Marina Bay offers convenient access to many of the experiences that define life on Longboat Key.

Marina Bay

Spacious Bayfront Living Within Bay Isles

Marina Bay occupies a quiet waterfront setting just south of the Longboat Key Club marina within the gated Bay Isles community. The community consists of three residential buildings at 2410, 2450, and 2550 Harbourside Drive. Each building has ground-floor parking and five elevator-accessed residential floors, with only four residences per floor.

The original site plan placed the three buildings around a central pool and recreation area, with tennis courts at the western end of the property and Sarasota Bay along its eastern boundary. Marina Bay is particularly notable for the scale of its residences, generally offering three bedrooms and approximately 2,830 to 3,825 square feet of living area.

This low-density arrangement gives Marina Bay a distinctly private character while allowing every home to extend through the building from east to west.

Why Buyers Love Marina Bay

The space of a home, without the upkeep.

Marina Bay appeals to buyers who want the space of a large waterfront home without the maintenance responsibilities associated with single-family ownership.

Most residences offer three bedrooms and expansive living areas, with generous kitchens, dining rooms, primary suites, guest accommodations, and screened terraces. With only four residences on each floor, the buildings feel private, and the floor-through layouts allow natural light and views from both sides of the home.

The community also provides both bayfront and Gulf-front experiences. At home, residents have a heated pool and spa overlooking the bay. Across the island, the private Bay Isles Beach Club offers gated parking, direct access to the Gulf of Mexico, a large pavilion, tropical cabanas, grills, picnic facilities, showers, and restrooms.

The Story Behind Marina Bay

Three buildings, four distinct floor plans.

Marina Bay was developed in the early 1990s as a low-density waterfront condominium community within Bay Isles. Rather than constructing one large tower, the original plan divided the community among three buildings positioned around a central recreation area.

Building One

The C & D Plans

Building One contains the community's largest original floor plans, the C and D layouts, providing approximately 3,825 and 3,363 square feet of interior living area, respectively — proportions that remain one of Marina Bay's defining strengths.

Buildings Two & Three

The A & B Plans

Buildings Two and Three follow the A and B floor-plan configurations. The arrangement preserves open space between the buildings and gives the community a more residential scale than a single-tower development would allow.

Today, Marina Bay remains one of Bay Isles' more intimate condominium communities.

Residences & Amenities

Floor-through homes, built for scale.

Residences generally range from approximately 2,830 to 3,825 square feet of air-conditioned living area. Most layouts include three bedrooms or a convertible den, multiple bathrooms, large living and dining areas, breakfast spaces, media or family rooms, walk-in closets, utility rooms, and substantial screened terraces. Their floor-through orientation provides Sarasota Bay views from the eastern lanais and western exposures from balconies on the opposite side.
