Windmill Harbour

Situated immediately upon crossing the J. Wilton Graves Bridge, Windmill Harbour is a 172-acre private community that serves as the premier deep-water gateway to Hilton Head Island. Renowned for its distinct Charleston-style architecture and its 15.5-acre yacht basin, this coastal enclave represents one of the most stable and affluent residential nodes in the Lowcountry. With its unique lock-controlled harbor—one of only three on the Eastern Seaboard—Windmill Harbour merges luxury waterfront living with unparalleled access to the Intracoastal Waterway. 

 Growth & Commercial Opportunities

While Windmill Harbour itself is a private, highly amenitized residential and marina community, its strategic location and high-net-worth demographic act as a powerful catalyst for commercial real estate in the surrounding Jenkins Island and Bluffton-Hilton Head corridor. 

Captive Affluent Demographic: With a median home price approaching $900,000 and waterfront estates exceeding $2.9 million, the community houses a wealthy base of primary and secondary homeowners. This drives sustained demand for premium commercial services in the immediate vicinity, including boutique wealth management, specialized healthcare, and high-end retail. 

Specialty Commercial Assets (Marine): The community’s 258-slip marina presents unique alternative commercial investment opportunities. Boat slips in the tide-free, secure harbor are highly coveted specialty assets, trading actively (often between $50,000 and $200,000+) and offering potential for rental income and steady appreciation. 

North End Corridor Expansion: As the first community on the island, the area immediately outside Windmill Harbour’s gates is primed for supportive commercial development. The seamless economic blend between Bluffton and Hilton Head positions this Highway 278 corridor perfectly for mixed-use and professional office spaces catering to the Lowcountry’s influx of residents. 

High Resident Retention: Over 65% of residents have lived in the community for more than five years, providing a stable, reliable consumer base for local commercial enterprises rather than transient tourist traffic. The prohibition of short-term rentals further stabilizes this neighborhood demographic.
