Welcome to 419 Golden Gate Avenue—arguably the most coveted address on Belvedere Island. Perched above the Bay with commanding, unobstructed views of the Golden Gate Bridge, Sausalito, Angel Island, and the Corinthian Yacht Club, this street-to-street lot presents a once-in-a-generation opportunity to build an architectural masterpiece in one of California’s most exclusive enclaves. One of the few properties on the island that offers both east- and west-facing views, the site captures the full drama of sunrise over Tiburon and moonrise behind the Golden Gate. Whether you choose to enjoy the existing chic pied-à-terre or embark on creating a world-class residence, the potential is limitless. The two-level pied-à-terre features a three-car garage and two separate studio suites—ideal for weekend escapes, guest stays, or income potential while you design your dream estate. The street-level suite includes floor-to-ceiling windows plus slider opening to a patio with breathtaking vistas and a private bath. Upstairs, a second studio offers a kitchenette, office nook, private bath, and expansive deck overlooking the Golden Gate, Sausalito, and the shimmering Bay. Golden Gate Avenue is a quiet, prestigious stretch of Belvedere Island surrounded by Marin’s most significant estates. From this elevated vantage point, you’re just minutes from downtown Tiburon’s waterfront promenade, two renowned yacht clubs, and upscale dining—including Michael Mina’s Bungalow Kitchen and Malibu Farm. Secret stairways connect you to downtown, while a quick ferry ride or scenic drive places you in San Francisco in under 30 minutes. Perfectly positioned for both adventure and serenity, this location offers effortless access to the best of Northern California: just an hour from Napa and Sonoma wine country, and three hours to Lake Tahoe for skiing and summer retreats. This is more than a home—it’s a chance to create a legacy in a setting that defines luxury, privacy, and panoramic beauty.
