Description:  The building .faces east and is a three story rectangular gray colored stone faced and concrete structure. The rectangular shaped building is located on landscaped grounds in the center of Plankington. Vertical bands divide the windows on the second to third stories. Vertical bands are on either side of the main east entrance. Interior finishes throughout the building are simple and austere. Floors are terrazzo, walls plastered, and ceilings covered with historic acoustical tile. Interior doors are oak with three recessed panels and without trim; door hardware displays an art deco motif. Historic wall mounted, stainless steel light fixtures remain in the stairways. The County Circuit Court courtroom, which occupies the southern half of the third floor, is finished similarly to the remainder of the building. The historic art deco-style furnishings, however, impart a perception of formality to the space. The finely designed and grafted pieces are constructed of two contrasting woods. The lighter wood is used as a band of fluting to top the furnishings and also to highlight other surfaces. The building houses the County Circuit Court of the 1st Judicial District and the County Magistrate Court. This was a Works Project Administration project..
