RBDG provided programming, layout, design, and acoustics for the audio production studios of National Public Radio at 635 Massachusetts Ave. N.W. in Washington, D.C. The 152,000 sq. ft. technical facility includes nine primary control rooms and studios for news and performance, eight feed/transfer rooms, production master control, and numerous editing and support areas. There are also auxiliary technical spaces for telecommunications, engineering services, a satellite depot, computer information services, numerous equipment rooms, and a roof-mounted satellite antenna plant.
Structural modifications to the existing building allowed high ceilings in the studios, which can accommodate large musical ensembles, radio drama, and live performances with audience. Private, glassed-in viewing areas were designed to allow visitors to watch production of “All Things Considered,” “Morning Edition,” “Performance Today,” and “Talk of the Nation” without impeding show routine.
