Physically linked to the L'Enfant Plaza Metro Station south of the National Mall, the eight-story tall 950 L'Enfant Plaza was developed in 1967. "It is situated within blocks of numerous government agency headquarters and is ideal for government contractors seeking space in close proximity to those headquarters," Howell says. The property, which Heyman bought on behalf of L'Enfant Colony four years ago for $55 million, has long been home to Federal Government offices including the local office of Sandia National Laboratories.
