15 William St

15 William Street is a 47-story condominium tower completed in 2005, occupying a prominent site in Lower Manhattan's Financial District. The 320-unit building was developed in a contemporary idiom with expansive double-glazed windows and high ceilings that emphasize light and views. Residences range from studios to three-bedroom apartments and typically feature open floorplans, built-in home offices, high-end chef kitchens with integrated Miele and Sub‑Zero appliances, Burmese teak flooring, multi-zone climate control, generous storage and walk‑in closets, and in-unit washers/dryers. Bathrooms are finished with Corian vanities, deep soaking tubs and separate rain showers. Shared spaces are extensive and varied: a penthouse sky lounge with wraparound terrace, landscaped terraces and garden, children's playground and playroom, 45‑seat screening room, covered dog run, and a Zen garden. Nearly 18,000–30,000 square feet are devoted to wellness and recreation, including a natural-light fitness center, indoor 50' heated saltwater lap pool, outdoor hot tub, sauna and steam rooms, yoga studio, indoor squash court and outdoor half-court basketball. Building services include 24-hour attended lobby, concierge/valet and a live-in resident manager; onsite parking is available. Private outdoor spaces—balconies and terraces—appear on select residences. Located steps from major subway lines, PATH, ferry access and dense retail and dining, the building blends full-amenity high-rise living with immediate downtown connectivity.
