Listing description
About this home
Virtually Staged. Under Construction. Under Construction.
Pre-Construction | Custom Build | Water to Front & Rear A once-in-a-generation opportunity on one of Longboat Key's most extraordinary streets. Lyons Lane is a truly singular address — a quiet, private enclave in North Longboat Key where homes enjoy an exceptionally rare double-water setting, with sparkling canal frontage to the rear and serene, protected wetland and mangrove views to the front. This is island living at its most private and unspoiled.
Design Your Dream Home The vision is still yours to shape. The buyer has the rare opportunity to work directly with the architect to customize the layout, finishes, and features of this brand-new custom home before it's complete. From floor plan adjustments to material selections, this is your chance to create a residence that is uniquely and entirely your own without the years of planning that a true ground-up build typically demands.
The property sits on a prime lot with water on both sides; the property includes an existing pool ready to be incorporated into your design, along with a private boat dock and lift with direct access to Millar and Sarasota Bays and no fixed bridges to the Gulf of Mexico. For the boating enthusiast, it simply does not get better than this deep water access, protected dockage, and open water within minutes. Lyons Lane — Longboat's Best-Kept Secret Unlike any other street on the island, Lyons Lane offers homes on one side only, with lush native mangroves lining the opposite side — ensuring that your views, privacy, and natural surroundings will never be compromised.
It is one of the few locations on Longboat Key where you can wake up to undisturbed natural beauty in every direction while remaining just moments from the finest dining, boutique shopping, and white-sand Gulf beaches the island has to offer. Longboat Key — Florida's Premier Barrier Island. Stretching 11 miles along Florida's Gulf Coast with over 25 miles of combined waterfront between the Gulf of Mexico and Sarasota Bay, Longboat Key is consistently ranked among the most desirable addresses in the country.
The island attracts discerning buyers who demand privacy, natural beauty, and world-class amenities — including the legendary Longboat Key Club, with 45 holes of championship golf, a full-service deep-water marina, spa, and beach club. Opportunities like this — a custom home, double waterfront, dock and lift, and the freedom to personalize are extraordinarily rare on Longboat Key. Don't miss your chance to build exactly the island life you've always envisioned

The Messtimate™
The Messtimate
This is a deliberately dumb estimate — living area times a range of recent neighborhood $/sq ft, and nothing else. It is not an appraisal, not market value, and not a valuation of this home. Even a tight range from comparable sales can’t price a specific home — here’s why.
$2,257,350the mess$2,875,470
Actual list price: $2,850,000 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 27% spread on the same house — and that gap is exactly what an automated guess can't see:
Condition & finishes — as new construction, builder upgrades and finish level aren't in a sq ft number.
The lot — this listing is waterfront; water frontage is priced far off a per-sq-ft average of the neighborhood.
Outliers skew it — one flip or distressed sale in the comps drags the whole $/sq ft up or down.
Carrying costs & concessions — CDD, HOA, insurance, and seller-paid buydowns change what a buyer actually pays.
The pool — a private pool carries cost and value that living area doesn't capture.
And here's what the live market is doing — which the number above ignores entirely:
This home: 216 days on market vs. a 80-day community median
3764 active listings competing, 1223 under contract
For reference, this home is listed at $2,850,000 ($941/sq ft) — a number set with analysis a Messtimate can't do.

Jul 2026 · Infrastructure
Florida's new state budget funds five major Manatee County projects
The 2026 state budget signed by Gov. Ron DeSantis directs 12.4 million dollars to five Manatee County projects, including the Singletary Road Bridge replacement, a 51st Street West extension in Bradenton, and design work for a Fort Hamer Road and I-75 interchange. The list also funds Fresh Start Manatee Phase 2 and the Valor Commons veterans hub.
Why it matters: State funding for road, bridge and interchange work expands transportation infrastructure and supports future growth capacity across Manatee County. The site is about 4 miles east of Zz Stellar Manatee Unassigned.
The Manatee County Commission advanced business terms for the next phase of an 80 million dollar, 190,000 square foot sports complex at Premier Sports Campus in Lakewood Ranch, featuring four ice rinks including a 2,500 seat arena plus retail, restaurants and sports medicine space. Construction is expected to begin in 2027 with an opening targeted for 2028.
Why it matters: A large ice and sports complex adds indoor recreation and commercial space to the Lakewood Ranch area and expands the local sports tourism venue base. The project is about 18 miles east of Zz Stellar Manatee Unassigned, elsewhere in Manatee County.
The City of Bradenton held a ceremonial groundbreaking for Future City Park next to LECOM Park, adding three new baseball fields, expanded parking and a community resource center offering education and career programs. Officials aim to complete all phases by 2028.
Why it matters: New ballfields, parking and a resource center expand public recreation and civic facilities in the Bradenton area. The project is about 3 miles east of Zz Stellar Manatee Unassigned, elsewhere in Manatee County.

Before you decide
Buyer research checklist
Items worth confirming for 640 Lyons Lane, chosen from what the record shows. This is general guidance, not advice about this specific property.
New construction: get the builder's warranty terms and the certificate of occupancy in writing, and ask which finishes shown are upgrades.
The listing reports no HOA: confirm with the county record that no deed restrictions or mandatory association apply to this parcel.
FEMA flood zone AE: lenders generally require flood insurance here — get an elevation certificate and a flood quote before the inspection period ends.
Get a homeowners insurance quote for this specific address in Manatee County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
Private pool: confirm the barrier or alarm meets the state residential pool safety code and ask for pump, heater, and resurfacing records.
Waterfront: confirm seawall or dock condition and permits, and ask who owns and maintains the shoreline.
Listed living area is 3,030 sq ft: verify it against the property appraiser's record and measure before relying on it.
Order a survey to confirm lot boundaries and easements.
Review permit history with the county.
Property taxes: the estimate on this page (about $29,925/yr) assumes reassessment at the list price; the seller's homestead cap does not transfer, so their current bill is not a guide.
Confirm school zoning directly with the district.

Frequently asked questions
How big is 640 Lyons Lane and when was it built?
Per the listing record, 640 Lyons Lane was built in 2026 and has 3,030 sq ft of living area, 4 bedrooms and 4.5 bathrooms. Living area and lot size come from the MLS record and should be verified against the county property appraiser.
What community is 640 Lyons Lane in?
640 Lyons Lane is in Sleepy Lagoon Park 2 in Longboat Key, Manatee County. The community section on this page shows recent closed sales, days on market, and active inventory for Sleepy Lagoon Park 2 from the same MLS data.
Does 640 Lyons Lane have an HOA?
The listing reports no HOA. Confirm with the county record that no deed restrictions or mandatory association apply to the parcel.
Why might property taxes on 640 Lyons Lane differ from the current owner's?
The estimate on this page (about $29,925 per year) assumes reassessment at the list price. Florida's Save Our Homes rule caps annual assessment increases for homesteaded owners, and the assessment resets after a sale, so a new owner's bill may differ from the seller's. Any tax figure shown here is an estimate, not the actual bill — confirm with the county property appraiser and tax collector.
Is 640 Lyons Lane in a flood zone?
The FEMA flood map places this parcel in Zone AE, a special flood hazard area where lenders generally require flood insurance on a mortgaged purchase. Confirm the parcel's status with FEMA and your insurer, and ask for an elevation certificate.
Can I rely on the figures on this page?
No. Estimated taxes, insurance, payments, and any market or comparable-sales summary are opinions and estimates for general information only and should not be relied upon. Verify all information independently before making any decision.
