A 4,000-square-foot, six-bay auto-repair service center including a mezzanine level with storage space, an office and restroom. A sunscreen of aluminum louvers was designed for the exterior walls to block direct sunlight from the building shell and thus reduce heat gain - a special problem in the hot climate of southeastern North Carolina. Besides also serving as a signature visual feature to attract customers from the main road, the louver system satisfied a requirement of the local ordinance that long facades be broken up visually by vertical column elements.
