▾The Residence
New construction completed in 2026, this five-bedroom, 5.5-bath harbourfront residence on Sparwheel Lane offers more than 5,200 heated square feet inside Windmill Harbour — Hilton Head Island's lock-controlled marina community, where panoramic views stretch across the harbour to the Intracoastal Waterway. An end-unit position on a corner lot gives the main living areas their reach: expansive windows frame the water, 7-inch white oak floors run warm underfoot, and an interior fireplace anchors rooms designed equally for refined living and effortless entertaining. The chef's kitchen is the showpiece — custom inset cabinetry, fully integrated paneled appliances, stainless finishes, craftsmanship held to the same standard throughout. Windmill Harbour's locked harbour and its South Carolina Yacht Club setting make protected, depth-controlled water access the defining amenity here. Finished, titled, and ready — nothing to build, nothing to wait for.
The Highlights
Set on a corner homesite within the gated deepwater enclave of Windmill Harbour, this newly built 2026 residence looks out across the harbour to the Intracoastal beyond, where the community's tidal lock holds the water steady and the boats sit at rest. Inside, soaring ceilings carry 5,200 square feet across five bedrooms and six baths, while the porch draws the day outward toward the water. A three-car garage completes a home built for life on the Lowcountry coast.
The value
At this level, value rests less on square-foot comparison than on what can't be reproduced — new construction completed in 2026 in Windmill Harbour. Offerings of this kind are genuinely limited, which is what sustains their position in the market.

The Setting
Windmill Harbour is a gated deepwater marina community on the northwestern shore of Hilton Head Island, distinguished by a tidal lock system that maintains consistent water levels within its protected harbour. The community is home to the South Carolina Yacht Club and offers direct access to the Intracoastal Waterway, making it a natural gathering point for serious boaters along the Lowcountry coast.

Questions
A hydraulic lock neutralises the tide, holding a constant eight-foot depth inside the basin no matter what the water is doing outside. It opens on demand 24 hours a day with keycard access, or 8am–7pm with harbormaster assistance.
The lock chamber measures 75 feet by 19 feet, and the marina accommodates vessels up to 70 feet LOA. If your boat is near that ceiling, measure beam and LOA against those figures before you commit — Christopher Hughes can confirm current marina specifics.
Dockage is arranged separately — a slip is not conveyed with this residence. Slips within the harbour are held and transferred independently of the homes, so your boat plan is a parallel conversation to the purchase, and Christopher Hughes can walk you through current availability.
No — Windmill Harbour prohibits short-term rental and enforces a minimum lease term, so this is a primary-residence or second-home purchase rather than a rental-income play. Christopher Hughes can confirm the current minimum term in the covenants.
Four layers: POA dues (which differ by property class), a one-time transfer fee at sale, an enacted 2026 special assessment, and a regime fee. The POA is managed by FirstService as of January 2026, and regime figures come from the regime manager directly — Christopher Hughes will pull the exact current numbers for this residence.
They are separate. The South Carolina Yacht Club sits within the harbour as its own club — with tennis courts, pool, sauna, bar and restaurant — while the POA governs the community itself. Club membership and POA dues are distinct commitments.
Scarce — Windmill Harbour is a built-out harbour community, so a 2026 new-construction residence of 5,200 square feet comes available rarely. Across the island's $1M-plus segment, inventory fell 15.3% while closings rose 12.0% through the first half of 2026.
The harbour opens directly onto the Intracoastal Waterway at mile marker 558, near channel marker 27 in Calibogue Sound — roughly a half mile south of the Pinckney Island Bridge. The lock is a genuine second entrance to the community, straight from the ICW.
This end-unit semi-detached residence offers 5 bedrooms, 5.5 baths, a 3-car garage and a porch across more than 5,200 heated square feet, with soaring ceilings, 7-inch white oak flooring and an interior fireplace. Christopher Hughes can confirm elevator and any additional features.
Windmill Harbour and Wexford are the island's locked-harbour communities, both built around protected deepwater basins rather than beach rental traffic. Hilton Head Plantation (Skull Creek Marina) and Sea Pines (Harbour Town, South Beach) also carry marinas, though Sea Pines is rental-oriented.
Yes — new construction at this scale on a harbour-view corner lot is close to unrepeatable in a built-out community, and the island's $1M-plus segment firmed through the first half of 2026 with closings up 12.0% on inventory down 15.3%. Sellers here have been landing within about 96% of ask.
It is an end-unit semi-detached residence, which means one shared wall and open exposure on the other three sides: more than 5,200 heated square feet, 5 bedrooms, 5.5 baths, a 3-car garage, soaring ceilings and panoramic marina views out to the Intracoastal — scale and privacy that read as detached living.
Two things beyond the house: securing dockage, which is handled separately from the home sale, and confirming your vessel fits the 70-foot LOA limit and the 75-by-19-foot lock chamber. Both are solvable pre-closing, and Christopher Hughes can sequence them alongside the contract.
Panoramic harbour views that stretch out to the Intracoastal Waterway, framed by expansive windows across the main living areas. The corner-lot, end-unit position on the harbour basin is what opens up that sightline.
