1 / 4About this home
Pre-Construction. To be built. Positioned directly across from the iconic St. Regis Longboat Key Resort, this exceptional waterfront residence offers immediate access to world-class amenities, pristine Gulf beaches, fine dining, and championship golf. Located within the exclusive double-gated Harbor Section of Bay Isles on Longboat Key, 1600 Harbor Sound Drive represents a rare convergence of scale, location, and boating capability, crafted for those seeking a refined Gulf Coast lifestyle at the highest level. Set on an expansive 18,043-square-foot corner homesite, the property features an impressive 135 feet of deep-water canal frontage, with the ability to accommodate multiple lifts (up to three) and a substantial vessel. This level of frontage and flexibility is increasingly rare, even among premier waterfront estates. Spanning 5,689 square feet under air, the residence is thoughtfully designed to balance grand-scale entertaining with comfortable everyday living. The home includes 5 bedrooms, a bonus room or office, 5.5 bathrooms, and a 4-car garage. Soaring ceilings and expansive glass openings create a bright, open environment with seamless indoor-outdoor transitions, complemented by refined, designer-level finishes and a private elevator servicing all levels. The chef’s kitchen is executed with top-tier appliances, clean architectural lines, and a level of detail rarely seen in spec construction. A full-scale butler’s pantry, complete with its own stove, provides exceptional functionality and allows for seamless entertaining while keeping the main kitchen pristine. The primary suite is designed as a true retreat, featuring separate his-and-her bathrooms and a fully integrated wellness experience, including a sauna and steam room, bringing a spa-level environment into daily living. Every element has been carefully curated to deliver comfort, functionality, and a sense of understated luxury throughout. Outdoor living is equally compelling, with a resort-style pool and spa, along with a fully equipped outdoor kitchen, covered dining, and lounge areas. These spaces are perfectly positioned to capture the tranquility of the waterfront setting while embracing Florida’s year-round coastal climate. Opportunities of this caliber, combining substantial frontage, strong boating capability, a wellness-driven design, and a premier Harbor Section address are increasingly limited. 1600 Harbor Sound Drive presents a compelling offering for the discerning buyer seeking a newly built waterfront estate in one of Sarasota’s most prestigious enclaves.

Heads up on that tax figure. On new construction, the number in the MLS is often the tax on the bare lot, not the finished home. Expect it to jump once the county reassesses with the house on it. How Florida reassesses new builds

CDD defaults to zero, and that is often wrong.Many Tampa Bay new-construction communities carry a Community Development District assessment of roughly $1,500 to $3,000 a year on top of HOA, and it is rarely included in a builder's payment estimate. Ask whether this address is in a CDD before you budget.
The tax figure in the MLS looks like a bare-lot assessment. It lists $24,527 a year, while taxing this purchase price works out closer to $213,300. On new construction the county reassesses once the house is finished, so budget from the higher number.

Here is what this listing's numbers say about the builder's position.
On the market 159 daysWorth knowing
Past the 90-day mark is where most builders start getting more flexible on concessions, even while holding the published price.
Pre-constructionContext
Nothing is built yet, so there are no carrying costs pressuring the builder. The trade is that you get design-center control and first pick of lots instead.
Where builders actually give
Rarely on the published base price. It sets the comp for every unsold home behind this one, and protecting it protects their appraisals. The real room is in closing cost credits, interest rate buydowns, and upgrades moved into the base. Asking for the right one in the right order is most of the job.
Assigned schools
