Since 1995 Southwest has been a leader in cutting-edge development of modified, custom built containers. We use the ISO shipping container that is 14 gauge heavy duty steel, and varies in length, all of which are 8’wide and 8’6” or 9’6” high. Our experienced, licensed and certified fabricators, engineers and designers are adept at customizing the container into just about anything you could imagine. Some examples include offices, guard shacks, homes, etc. We can modify by adding insulation, HVAC, electrical, windows, doors, wind turbines, sky lights, partitions, work spaces, flooring, etc. These portable units are much less costly and convenient than a conventional building, not to mention they’re portable and can move along with you if you so desire. Call us to speak with one of our sales team members to assist you in bringing your concept to reality!
