A pier foundation is possibly the best foundation for a shipping container home. It also happens to be the most popular choice as it’s low cost, easy to build, and super durable. A pier foundation consists of several concrete blocks that can improve the tension in your steel reinforcement. You will typically find these piers underneath each corner of the container, although we recommend adding even more for longer 40’ containers. This will ensure that you have a solid and stable foundation for your home. Other types of foundations include the pile, slab, and strip foundation.
