675 Marina Boulevard is an extraordinary Spanish Mediterranean residence set along one of San Francisco's most iconic waterfront boulevards. Positioned directly across from the Marina at St. Francis Yacht Club, this four-bedroom, four-and-a-half-bath home captures sweeping views of the San Francisco Bay, Alcatraz, and the Golden Gate Bridge while offering a level of architectural character and provenance rarely available today. Originally built during an era when craftsmanship defined San Francisco's finest homes, the residence is rich with timeless detail and scale. Arched passageways, soaring ceilings, elegant wrought iron accents, custom millwork, and beautifully curated interiors create a home that feels both sophisticated and deeply inviting. Natural light pours through the residence throughout the day, illuminating the warm textures and refined architectural lines that define its Spanish Mediterranean character. Beyond its beauty, the home carries a remarkable legacy. Over the course of nearly 100 years, 675 Marina Boulevard has changed hands only twice, quietly reflecting the rarity and significance of this offering. Homes of this caliber and position along the Marina waterfront are seldom available and often held for generations. Life here is inseparable from its surroundings. Mornings begin with the calm of the Bay just outside your windows. The Marina Green, Crissy Field, and the city's northern waterfront become an extension of everyday living, whether for a morning run, surfing, a bike ride along the shoreline, paddle boarding or an evening walk beneath the Golden Gate Bridge as the sun sets across the water. Just moments away, the restaurants, cafes, and boutiques of Chestnut Street offer one of San Francisco's most vibrant neighborhood experiences.
