Resources for Human Development is a large non-profit organization, which administers numerous social service programs from a network of sites spread throughout ten states. Their main office has retained Stokes Architecture to plan a 20,000 sq ft expansion, doubling the size of the existing rhd office. Located in a large industrial building that once housed the Philco radio factory, the original office was built with an impressive sawtooth roof. The expansion exposes the roof's existing skylights, and arranges offices in an open plan as a series of neighborhoods with a central street connecting the various departments. Space is organized around a café and an indoor park, containing informal seating, facilitating interaction among the staff. Numerous meeting rooms and private spaces are provided as free standing objects, most of which are glazed with polycarbonate.
