Interior Design classes conducted at the NVCC Loudoun campus are held in the newest campus facility, the Waddell Building. Classes are typically held in room 206 of this building. This facility contains twenty-two drafting tables, several light tables, and periodical materials for student use. The state of the art classroom also contains a computer and computer projection for instructional purposes. VCR, DVD and overhead projection are also available in the classroom.

Adjacent are two rooms used by the program, a materials resource library and a copy/plot room. The Interior Design Resource Library is used by students to research and prepare class assignments. This room is filled with carpet, wallcovering, flooring, fabric and other materials used in the design of the interior environment as well as layout tables and mat cutting equipment to prepare design presentations. The Copy/Plot Room is used for large document copying and plotting of assignments.
