Residence 21E at 15 William Street is a spacious and light-filled two-bedroom, two-bath home in one of Downtown Manhattan’s premier full-service condominiums.

This corner residence boasts floor-to-ceiling windows and soaring ceilings, flooding the home with natural light and offering sweeping city views. The open-plan living and dining area is ideal for entertaining, with a chef’s kitchen featuring custom cabinetry, Caesarstone countertops, and top-of-the-line appliances by Miele, Gaggenau, and Sub-Zero.

The primary suite accommodates a king-sized bed, includes a large walk-in closet, and a spa-like ensuite bath with a deep soaking tub, rain shower, and double vanity. The second bedroom is generously sized — perfect as a bedroom, home office, or guest suite — with an adjacent full bath. An in-unit washer/dryer completes the convenience of this beautiful home.

Located in the heart of the Financial District, the building is steps from the South Street Seaport, the World Trade Center, Wall Street, Fulton Center, and multiple subway lines — providing seamless access to the rest of the city.
