Unmatched Development Potential

A rare blend of pedigree and opportunity, this estate on Rose Hill Road combines the timeless charm of a 1925-built Georgian residence with expansive development possibilities on its prime 5.27-acre+/- waterfront parcel. Crafted by the noted early 20th-century architects Frank Goodwillie and William E. Moran, the property boasts historic allure while offering vast potential for transformation. Set on 5.27 acres+/- with 330' of prime water frontage+/-, this estate holds substantial development possibilities. Zoning and FEMA Zone X classification allow for the potential subdivision of the property, making it ideal for creating a large, private compound or subdividing the property to fit multiple full programs. The land provides ample space to envision a large main residence, private tennis or pickleball courts, and a waterside heated gunite pool and spa with a pool house. These development capabilities make this an extraordinary opportunity for discerning buyers to build an estate tailored to personal vision and lifestyle.
