20 West 15th Street is a boutique condominium located in Flatiron and Union Square, developed by Peak Capital, and completed in 2026. Its nine residences are organized around private outdoor space: the building has one maisonette with a private garden, while six of the seven floor through apartments have private balconies, and a duplex penthouse has a private roof terrace.
The apartments have direct elevator access, engineered hardwood floors, marble kitchens with integrated appliances, primary bathrooms, central air conditioning, and in unit washer and dryers. The layouts include both the garden maisonette and floor through residences, with private terraces or balconies forming a recurring feature of the building's design.
Residential amenities include bike storage and a common roof terrace, and pets are allowed. The building's compact scale and private outdoor spaces distinguish it from the larger condominium buildings typical of the surrounding neighborhood.
20 West 15th Street is just up the street from Union Square Park, with restaurants, retail, and cultural institutions in Greenwich Village, Chelsea, and Gramercy close by.
