Ready to live directly on the Gulf? This Seaward Homes Curated Collection residence at 6489 Gulfside is move-in ready, with direct Gulf-front private access and stunning views of the Gulf of Mexico. Designed by DSDG Architects and staged by Clive Daniel Homes, the home pairs cutting-edge, hurricane enhanced construction with exceptional quality and attention to detail throughout. Set on a coveted 90' Gulf/beach-front lot, the property offers soft sand, endless Gulf views, and miles of walkability. In 2025, Longboat Key completed a major beach re-nourishment project, giving Gulfside Road homeowners one of the widest and deepest stretches of beach on the island. Gulfside Road is also one of the rare Gulf-side streets set back from the main highway, so the setting feels private and quiet, worlds away from the activity of Gulf of Mexico Drive, just minutes from Whitney Plaza and North Longboat Village, and moments from fine dining at Shore and Mar Vista. The main house is elevated over 15', with 11' ceilings, four oversized en-suite bedrooms, and more than 6,600 square feet of air-conditioned living space, including a grade-level, air-conditioned multipurpose room ready for a home gym, a wellness studio, or whatever fits your lifestyle. The wide-open floor plan, generous room sizes, and large impact-rated safety glass sliding doors and windows fill the home with natural light. Two nearly 40' terraces, one on the main floor and one on the second, are ideal for enjoying the outdoor island lifestyle and breathtaking Gulf views. Interior finishes by Studio G Homes take the home to the next level, with large-format porcelain tile and hardwood flooring, Italian-imported cabinetry, a custom floating steel-and-wood staircase, a three-stop elevator, 8' solid interior doors, high-efficiency mechanical systems, a top-of-the-line Thermador™ appliance package, AXOR™ and Hansgrohe™ plumbing fixtures, temperature-controlled wine storage, and detailed AV, lighting control, and security systems. Exterior features include solid concrete and masonry construction on all floors, a deep concrete piling foundation for added strength, premium Longboard™ aluminum architectural details, and a fine light-sand stucco exterior. A resort-like pool and spa are surrounded by lush tropical landscaping, and the four-car garage leaves room to add car lifts. Longboat Key is an 11-mile barrier island just minutes from St. Armands Circle and downtown Sarasota, with Sarasota Bradenton International Airport about 25 minutes away. This is a rare chance to own this level of coastal luxury directly on the Gulf, don't wait!

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 $42,641 a year, while taxing this purchase price works out closer to $251,010. On new construction the county reassesses once the house is finished, so budget from the higher number.

Get the real numbers on this homeWhat is negotiable on this home?
This listing shows real leverage signals. Here is what its own numbers say.
On the market 261 daysStrong signal
Past six months on a finished home means the builder has been carrying taxes, insurance, and interest on it the whole time. That cost is real and it is why concessions get easier the longer a home sits.
Reduced $1,000,000 (7%)Worth knowing
Originally listed at $14,995,000. A builder that has already cut once has acknowledged the first number did not work. That is a different conversation than one who has never moved.
Finished and standingWorth knowing
A completed home with a Certificate of Occupancy is inventory, not a future sale. Builders treat standing inventory very differently from a lot they have not broken ground on.
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.
