An exceedingly rare opportunity within one of Newport Beach's most prestigious enclaves. Sited on a coveted stretch of one of the most desirable waterfront streets, 612 Harbor Island Drive features stunning vistas of Promontory Bay and a private dock capable of berthing up to two approx. 56-foot vessels and a Duffy. The generous frontage makes access to the bay seamless, a perfect setting for enjoying the coastal environment, while the location offers respite from the road noise. This residence, with an updated kitchen, presents an incredible chance for those looking to further renovate the existing structure or build anew. The living and sleeping quarters feature tranquil views of the water, creating a serene environment. While separated from the street by a privacy gate, the most exciting amenities of this area are just minutes away: from dining, to shopping, and endless beaches. The potential of this residence, in the heart of the most desirable expanse of Promontory Bay, is truly boundless.
