The Hill recently underwent the Northwest Campus In-fill Project, which added an additional 1,525 beds, 10 faculty in-residence apartments, a 750-seat dining hall, and four residential towers in 2013. At that point, UCLA will be able to house 12,000 undergraduates, and will begin plans to provide a four-year housing guarantee for all incoming freshmen. Two of these buildings, Holly Ridge and Gardenia Way, which are part of De Neve Plaza, opened February 2012. The other two, Sproul Cove and Sproul Landing, were completed in September 2013. Sproul Cove stands on the previously-unoccupied ridge below Rieber Hall. Sproul Landing stands on the former site of the Office of Residential Life, which has relocated to Tom Bradley International Hall.
