The Metro Plaza II center offers 11th-floor views of Silver Spring's central business district and is just minutes from downtown Washington, DC. It is situated in one of three buildings that make up the landmark Metro Plaza, which is directly accessible from the Silver Spring Metro station (Red line) and the MARC commuter rail service. The building has Energy Star certification for operating efficiency and boasts high-quality contemporary finishes, a central pedestrianised area with fountains and on-site amenities that include a café, shops and underground parking. The center is a short walk from downtown Silver Spring, but is also close to Interstate 495 and within 30-45 minutes of three major airports. Affluent Silver Spring is a major business hub to the north of the US capital. The economy is dominated by the services sector and its proximity to the center of national government. The defense/aerospace industry thrives in this region and there are many educational and medical research institutions.
