The five-story, south-facing building is located on a plot of approximately 70,000 square feet. The site is bounded on the south by 2nd Street NW, on the east by E Street NW, on the north by 3rd Street NW and on the west by D Street NW. In general, the building’s exterior is designed as a cantilevered block resting on a two-story podium, flanked by similar blocks to the east and west. There is an open plaza in front of the building comprising a central reflecting pool bounded on east and west by walkways lined with trees. The plaza is built on an elevated deck over Interstate Route 395, which runs beneath the plaza from east to west.
The building contains 151,420’ of floor space; the square footage is divided into 343 interior spaces plus a lower-level garage which accommodates approximately 100 cars. Of the 343 interior spaces sixty-three are used to provide public conveniences or service function for the building; the remainder of the spaces are used as courtrooms, offices, and related functions of the Tax Court. The most prominent interior space is a central public hall, called the Hall of Justice, which is four stories high and has a clerestory ceiling. The four-story public hall, visible above the podium, acts as the main circulation zone, linking all parts of the building. Four-story units on the north, south, and west sides of the hall contain offices and judges’ suites, while the cantilevered block on the east houses three courtrooms. Galleries with plate glass railings open onto the Hall of Justice from the adjacent office and courtroom blocks The courtroom block which projects from the east wall of the public hall contains three, two-story courtrooms; a large courtroom in the center and two smaller courtrooms on the north and south. The first-story podium of the building provides court support facilities: library, dining areas, storage facilities, mailrooms, and operations offices.
Exterior finishes of the building are Royal Pearl granite and bronze-tinted glass with narrow bronze anodized aluminum mullions. Exterior handrails were fabricated from bronze tubing. Interior finishes utilize a number of materials associated with the Modern Movement including concrete walls, louvered teak screens, and a tongue-in-groove hemlock plank ceiling in the Hall of Justice. The plaza also uses granite in the cladding of the reflecting pool, walkways and exterior stairways.
