Building 40, Army Medical School is a Georgian revival structure in the Walter Reed Army Medical Center complex in northern Washington, D. C. The MDPSS ultimately became the Walter Reed Army Institute of Research and it comprises four wings, known as the Craig, Sternberg and Vedder, and Siler Pavilions and is situated at 14th and Dahlia Streets. The original block of Building 40 is designed in an elaborate version of the Colonial/Georgian-Revival style established in the nearby Walter Reed General Hospital. The large, brick, three-story building is embellished with elaborate classical limestone trim at its entrances, the three main floors are brick, rusticated on the first floor and smooth on the second and third, with stone belt courses and a deep projecting dentilled stone cornice. A high parapet surrounds the flat roof and it is a complex brick and limestone structure, consisting of an original H-shaped block and a lster addition on the west. The original block appears to have designed as a unit. The east elevation was intended to be the principal façade of the original building. The main entrance is located in the center of the crossbar of the H, today, air conditioners and pipes, probably used for ventilation, protrude from all major elevations. The entire building is now vacant and in bad condition, with broken windows. The long north and south pavilions of the building are virtually identical. The south pavilion was completed in 1924, but work on the north pavilion. The addition, the Siler Pavilion, was built in 1962. Within each side bay, rectangular stone panels combine the windows on the second, on the east ends of the wings, double entrance doors are set within molded stone surrounds and brick pilasters with stone pedestals and caps frame the windows on the second and third floors. An addition covers the entire west elevation of the original block, because the lot slopes slightly from east to west, this elevation is a full four stories high. The stripped Classical style of the addition was designed to harmonize with the original block, the limestone water table, belt course, and projecting cornice are simplified versions of the ones on the original block. Recessed metal panels tie the eight-pane metal-framed casement windows on the first, second, there are two simple double entrance doors at the basement level on the west elevation. There is a dock in the full-height basement level at the south end of the addition. In 1999, WRAIR relocated to its present Forest Glen, Maryland site, one of the earliest nuclear reactors in the United States was installed in the basement of the buildings addition
