Listing Description

Set within Newport Beach's most exclusive waterfront enclave, 21 Bay Island offers a rare combination of architectural distinction, direct harbor and yachting access, privacy, and effortless coastal living. Bay Island is a gated, pedestrian-only sanctuary of just 23 waterfront homes, reached by foot or golfcart over a charming private bridge, where

lush picking gardens, mature trees, a private sandy beach, and sweeping harbor views create an atmosphere unlike anywhere else in Newport Beach - moments from the Balboa Peninsula and steps from the Pacific Ocean. Designed by acclaimed architect Kurt Donat and built by Neil Longman Construction, this Hamptons-inspired residence blends timeless nautical character with the scale and comfort expected of an ultra-luxury waterfront home.

Polished hardwood floors, crisp white millwork, refined coastal finishes, expansive entertaining spaces, and walls of windows evoke the elegance of a classic yacht while framing captivating views of Newport Harbor. Generous living areas open naturally to terraces, gardens, and the water, creating a seamless setting for intimate gatherings, grand entertaining, or quiet evenings watching sunsets and boats cross the harbor.

A private elevator serves the home, while multiple fireplaces, a waterfront spa terrace, and a light-filled upper-level great room enhance its exceptional comfort and character. For the boating enthusiast, the property delivers the ultimate Newport Beach lifestyle with a private dock, and immediate access to the harbor's main channels.

Begin the day on the water, cruise the coast, and return home for a sunset overlooking the bay. Bay Island's private beach, beautifully maintained gardens, waterfront pathways, and intimate residential character make it more than a neighborhood-it is a world apart.

Few properties offer this combination of prestige, tranquility, walkability, boating access, ocean proximity, and architectural pedigree. Bay Island represents the pinnacle of Newport Beach living: private yet connected, refined yet relaxed, and surrounded by the beauty of the water.
