The Grand Penthouse at 181 Fremont is the boldest expression of luxury living on the West Coast. Spanning 6,941 square feet, it occupies the entire top floor, rising more than 700 feet above San Francisco as the city’s highest residence. Floor-to-ceiling glass frames sweeping panoramas of the Pacific Ocean, Marin Headlands, the Golden Gate Bridge, Bay Bridge, Transamerica Pyramid, Salesforce Tower & Park, and the skyline in its full grandeur. This extraordinary home offers four bedrooms, six and a half baths, and a collection of living spaces designed to inspire. A grand dining room, magnificent primary suite with unobstructed north and west views, dual spa-inspired primary baths, private gym room, and exhibition-style kitchen with custom cabinetry come together in seamless harmony. Every detail reflects precision, intention, and timeless elegance. Every window presents a masterpiece. Every vantage point is unrepeatable. The Grand Penthouse represents the ultimate expression of luxury in San Francisco. There is only one highest home in San Francisco. Only one residence occupying an entire 70th floor. Only one place where you live above the clouds, above the bridges, above it all. Arrival begins with a private elevator ascending to a personal foyer, where a custom Lolli e Memmoli crystal chandelier floats above Grigio Carnico leathered marble floors. A burnished brass entry door with a custom-forged handle by Parisian atelier Série Rare introduces a residence where every element has been meticulously curated. Venetian plaster walls, 10.5-foot ceilings, and wood flooring in an intricate Marie Antoinette pattern create a warm, refined backdrop. The parlor is anchored by a full-slab Carrara marble dual-sided fireplace and elegant wet bar. A grand dining room with wine cellar and tasting bar is designed for memorable entertaining, while a glass-enclosed study crafted with Rimadesio smoked glass and Henge bronze-and-walnut shelving provides both privacy and presence. Savant home automation and Lutron lighting integrate seamlessly throughout. The exhibition kitchen combines artistry and performance with Emperador marble countertops, Rossana custom cabinetry, Acciaio steel accents, and a sculptural wood bar top. A full suite of Gaggenau appliances includes refrigerator and freezer towers, double ovens, steam oven, wine tower, five-burner gas cooktop, integrated grill, and teppanyaki station. A separate catering kitchen features Sub-Zero refrigeration, Valcucine glass cabinetry, and a Miele double oven. The west primary bath is conceived as a private spa, featuring an Antonio Lupi soaking tub, radiant-heated statuary marble floors, Arabescato Corchia marble walls, and a steam shower. The north primary bath is wrapped in Salvatori Gris du Marais marble with radiant-heated surfaces and Gessi Rettangolo fixtures. A sculptural powder room finished in custom Italian titanium travertine completes the collection. The primary suite occupies the northwest corner, where panoramic views stretch across the Bay, Golden Gate Bridge, and Pacific horizon. Dual custom walk-in closets complete the retreat. Three additional bedrooms, each with en-suite baths and generous closets, enjoy the same rare privilege of elevation and outlook. 181 Fremont is the West Coast’s tallest mixed-use tower, an 800-foot exoskeleton-framed skyscraper engineered to exceed rigorous seismic standards and anchored directly to bedrock. Residents enjoy exclusive access to the full-floor Residents’ Club on the 39th level, featuring a wraparound observation terrace, fitness center with yoga studio, piano bar, private dining room, catering kitchen, lounges, media room, and conference facilities. White-glove service includes dedicated concierge, 24-hour lobby staff, valet parking, and direct skybridge access to Salesforce Park and the Salesforce Transit Center. Offered at $47,500,000
