20 Harbor Island, Newport Beach, CA 92660
Property Description
This landmark Newport Beach Harbor Island home, situated on two of its most extraordinary view lots, is available for sale for the first time in over 70 years. Favored for its timeless classic style, impressive private dockage, magnificent stately grounds, and beautifully manicured specimen trees, this gracious residence, built circa 1937, presides over Newport Harbor’s central turning basin and anchorage, the hub of the harbor’s yachting activity. This offering comprises two independent lots (numbers 20 and 21), each fifty feet wide. Their combined one hundred feet of frontage, found on the most desirable island in Newport Harbor, represents the last opportunity of its kind. Surrounded by Southern California’s most impressive and expensive waterside residences, this property can be restored, expanded, or wholly reimagined to build the waterfront home of your dreams. The existing private dock can accommodate several boats to 78’, and reconfiguration could allow for a yacht to 100’. Lot 21 can be purchased separately for $29,500,000.
