Single-story self-storage systems are the primary design for most self-storage projects. Its basic yet flexible design is easy to erect and modify to maximize the land. The One Story Self-Storage System allows for greater variety in bay sizes and eave heights by incorporating post and purlin construction. A key feature is the standard full 9′ wide doors on 10′ bays and full 11′ wide doors on 12′ bays. A wider door width offers easier access to the bay, which is especially important when renters use the unit for vehicle storage.
