Property details
About 21 Harbor Is
On offer is one of two lots from this iconic bayfront estate, being presented here in the form of one fifty-foot wide parcel with the address of 21 Harbor Island. Situated on Harbor Island - Newport Beach's most sought after address - and overlooking the main turning basin, this parcel features the very best views and the very best location one will ever find in Newport Beach on the water. This is a singular opportunity to acquire an unbuilt lot in an ultra-prime location upon which to create one's dream home on the bay. The building envelope is substantial and is complemented by a mature garden with stately trees and long green lawn running down to the water's edge. A relocated and reconfigured dock will accommodate up to an 85' yacht - possibly longer. No subdivision is necessary, as the lots have always been independent and were never merged. The home on the adjacent lot (20 Harbor Island) is available as part of a package offering of both lots for $59,000,000.
