Skip the years-long renovation and move into your custom home as soon as Spring 2027! Introducing One Helen, a rare opportunity to own a custom-quality luxury residence in the heart of Nob Hill. Located on one of San Francisco's most charming and private lanes, this shovel-ready opportunity offers the best of both worlds: an approved architectural vision with construction ready to begin, while allowing the future owner to personalize select finishes, subject to the stage of construction. Designed by acclaimed architect William Pashelinsky, this contemporary four-level home is planned for approximately 2,492 square feet with 3 bedrooms, 3 full bathrooms, 2 half bathrooms, an attached garage, and exceptional indoor-outdoor living. The thoughtful design emphasizes natural light, privacy, and effortless entertaining, featuring a chef's kitchen, luxurious primary suite, flexible fitness/media space, private garden, and expansive terraces. Just moments from world-class dining, boutique shopping, Huntington Park, the Fairmont Hotel, cable cars, and the Financial District, One Helen offers a rare opportunity to create a personalized luxury home in one of San Francisco's most iconic neighborhoods.
