A number of the former hospital buildings were incorporated into the new development including the former Kline Hall which now houses marketing offices, Lexington's cable access station, an auditorium and a fitness area. A large concrete relief from the medical-surgical building has been installed outside the building as a memorial to the state hospital. The extensive wooded grounds are open to the public and protected in perpetuity from further development. The trails include part of the Western Greenway open space, connecting to the Rock Meadow conservation area in Belmont to the east and, according to plans, in 2009, to the Middlesex County Hospital area to the west.
