Waterfront Penthouses in Bay Harbor Islands: Terraces, Views and the New Developments to Watch

Bay Harbor Islands is a small, low-rise island community on Biscayne Bay, and its newest condominiums are built on that scale: boutique buildings rather than large towers, with glass-heavy façades facing the bay or Indian Creek. In a market of this size, the top floors carry most of the architectural ambition. Penthouses here are where developers concentrate the largest terraces, the longest sightlines and, in some cases, private pools or rooftop space that other residences do not receive.

That makes the penthouse level the clearest way to compare the projects. Two buildings can both describe themselves as waterfront and still differ in what matters day to day: which water is in view, how the outdoor space connects to the living area, whether a boat slip is part of the offer and how far along construction is. The sections below take the developments for which published details exist and describe what each says about its upper residences, so buyers know what to verify when they request floor plans.

La Maré Bay Harbor Islands is presented on its official website as a set of three boutique waterfront collections rather than a single building. The Regency Collection, at 9927 East Bay Harbor Drive, is described as an eight-story building of 33 two- to four-bedroom residences, each with wrap-around, floor-to-ceiling glass walls and panoramic views of Biscayne Bay. The website also lists a private marina and an elevated rooftop pool deck among its amenities.

The Signature Collection is the most distinctive for anyone focused on outdoor space. According to the same website, it is a glass-clad, eight-story building at 9781 East Bay Harbor Drive made up of just nine residences, two to four bedrooms each, with panoramic bay views from every home, spacious terraces meant for indoor-outdoor living and private plunge pools. A building of that size means few neighbors per floor, which is the privacy argument the developer makes for it.

The third group, the Bay Collection, is described on the website as the pinnacle of the project, with what the developer calls the best views in Bay Harbor Islands. That is the developer's own characterization, and it is worth testing in person: ask which floors and exposures the claim covers, and request the terrace dimensions and orientation for any specific residence you are considering.

La Baia North is Continuum Company's waterfront condominium at 9481 East Bay Harbor Drive, the follow-up to its earlier La Baia South at 9201 East Bay Harbor Drive. Continuum's public materials describe penthouses with private outdoor space, along with private boat slips, yacht club membership and water-sports launch access. Together those make the project as much a boating address as a view address.

Interior details in the developer's materials point to a classic, hospitality-minded finish level: ceilings of up to 10 feet, Miele appliances, wide-plank wood flooring and marble baths. For the penthouse level specifically, buyers should ask for the terrace plans, since the public descriptions confirm private outdoor space but this article does not rely on dimensions beyond what the developer publishes.

On timing, the La Baia North news page on the developer's website carried a banner reading "Delivery January 2027. Final Residences Remaining," alongside posts dated October 21, 2026. Availability and delivery schedules change, so confirm the current status directly with the developer or the sales team before relying on that banner.

Bay Harbor Towers sits at 10141 East Bay Harbor Drive on the east island, along the northern shoreline where, as the project website puts it, the Indian Creek waterfront meets the expanse of Biscayne Bay. The website describes a boutique collection of forty-four private residences in two-, three- and four-bedroom layouts, and its status line reads "Now Under Construction. Delivering Early 2027" as of its 2026 version.

The residences are described as flow-through layouts with bespoke finishes, endless water views and boat slips, designed to separate common living areas from private quarters. Flow-through plans matter on the upper floors because they can bring light and water views to two sides of a home, which is a different experience from a single-exposure layout. The architect is Kobi Karp, with interiors by Steven G., according to published project descriptions.

Because the public materials do not detail individual penthouse terraces, the practical step is to ask the sales team for the plans of the top-floor residences, the outdoor square footage, which direction each faces and whether a boat slip is assigned to a given penthouse or offered separately.

THE WELL Bay Harbor Islands takes a different route from the boating-oriented projects. Developed by Terra, it is positioned as a wellness-focused residential building, designed by Arquitectonica with interiors by Meyer Davis. Its amenity program is built around bathing and recovery rituals, including a bath house, a saunarium and a caldarium.

For a buyer comparing penthouses, the question is how much of the value of a top-floor home lies in the private terrace and how much in the shared wellness program downstairs. If daily use of those facilities is the priority, The Well is built around it. If the priority is a private pool or a boat slip, the waterfront-specific offers at La Maré, La Baia North and Bay Harbor Towers are more direct matches.

Start with the water itself. Biscayne Bay frontage, Indian Creek frontage and a view over a rooftop to the bay are three different things, and project marketing does not always distinguish them. Ask which body of water a specific penthouse faces, at what height, and what could be built nearby. Then ask about the terrace: its depth, whether it is covered, whether it has a kitchen or plunge pool, and how it connects to the main living space.

Next, look at what comes with the home. Private boat slips, marina access, yacht club membership and rooftop amenities are described in the developers' public materials, but they are not always included with every residence. Confirm in writing whether a slip is part of the purchase, what size vessel it accommodates and how the rooftop or marina is managed.

Finally, compare timelines. Several of these buildings are still under construction, and the delivery dates cited on developer websites are targets that can move. Request the current construction schedule and the contract language that governs delivery. For help comparing specific floor plans, terraces and slips across these Bay Harbor Islands buildings, Denis Smykalov and the Wolsen Waterfront team can walk through the options.
