Used shipping containers, either 20' or 40', are a very cost effective way to build a cabin, shelter, or even a work shop. They are less expensive then new shipping containers, and provide the same sense of security. While there are differences, the cost/benefit of a used container makes sense in many different projects.
Used shipping containers are available throughout many locations around the United States and Canada and can be purchased and delivered quickly. A used container is typically in wind and water tight or cargo worthy condition, and are sold by shipping lines that no longer need them, either due to their location or strict international demands of intermodal shipping.
