This guard building photo gallery shows featured guard buildings of Little Buildings International. Little Buildings guard buildings, also known as large guard booths, large-size security booths, guard houses or security buildings are prefabricated, portable and pre-assembled in the Little Buildings factory with 100% welded steel construction. Typically, a welded steel Little Buildings portable guard booth or prefab security booth is delivered fully assembled to your facility on a flatbed truck and then the welded steel security booth is most simply off-loaded with a forklift. Larger guard booths, also known as guard buildings or guard houses may need a crane to off-load.
