CityCenterDC, colloquially called CityCenter, is a mixed-use development consisting of two condominium buildings, two rental apartment buildings, two office buildings, a luxury hotel, and public park in downtown Washington, D.C. It encompasses 2,000,000 square feet (190,000 m2) and covers more than five city blocks. The $950 million development began construction on April 4, 2011, on the site of the former Washington Convention Center—a 10.2-acre (4.1 ha) site bounded by New York Avenue NW, 9th Street NW, H Street NW, and 11th Street NW. Most of the development was completed by June 2015. Metro Center and Gallery Place, two of the city's busiest Metro stations, are within three blocks of CityCenter.
