These light commercial buildings have semicircular (culvert) shape roofs that curve to the ground to form the sides. These buildings have many uses, such as general material, commodity or equipment storage and repair, and are generally lighter than typical warehouse buildings. Interior modifications can turn them into any one of several uses. The better qualities will have some built-in shop or workbench cabinetry and adequate lighting and plumbing.
Note: Exterior wall choices are not available for this occupancy.
Availability of Elevators by Area for this occupancy: No
