Atop one of the highest floors of the Four Seasons San Francisco, this bespoke residence by internationally recognized firm ODADA is a refined modernist retreat. A rare offering, Residence 37EF unites two adjacent condos with flexibility, scale, and privacy in mind, showcasing sweeping views from Twin Peaks to Alcatraz. Spanning 4,000 sqft, the home includes four en-suite bedrooms, two living areas, and an office/library--ideal for multi generational living, independent use, or long-term adaptability. The larger Western Wing features expansive living, dining, and library spaces with coved ceilings, paneled walls, abundant light, and year-round sunsets. The library, enclosed by pocket doors, flexes as a private office or lounge. The kitchen includes a view-facing breakfast area. Both bedrooms offer custom en-suite baths and north-facing outlooks. A laundry area & server room with a secondary entrance provides discreet service access, and a stylish powder room with marble counters serves guests. The smaller Eastern Wing offers two bedrooms, two and a half baths, and wide, north-facing, city views. Its living area is supported by a full kitchen, in-home laundry, and half bath. The primary suite allows for both rest and retreat, while the secondary bedroom features a wall that slides open effortlessly expanding the living space or creating a private suite with a Murphy bed. With its own entrance, the Eastern Wing functions as a fully independent home. Reintroduce one wall to maintain two separate residences. Defined by its adaptability, this sophisticated home balances immediate comfort with lasting versatility, all set against sweeping views of the Bay and the iconic San Francisco skyline.
