Steps to Building Your Shipping Container Garage

1. Leveling and Site Preparation

Before placing the containers, ensure that the ground is level. Use a level and leveler to make sure the foundation is even. A stable foundation will prevent shifting and maintain the structural integrity of your garage.

2. Anchoring the Containers

For added stability, anchor each container by digging 3-foot-deep holes at the corners. Insert 6-foot steel square bars into these holes, ensuring 3 feet remain above ground.

Secure each bar by welding it to the container and pour cement into the holes to keep the bars firmly in place.The American Welding Society (AWS) offers valuable safety guidelines and resources for beginners.

3. Welding and Connecting Containers

Position the containers side-by-side, or in a configuration that suits your space. Weld them securely to create a unified structure. Welding ensures that the containers won’t shift over time.

4. Adding a Roof

If you live in an area with heavy rainfall or snow, a roof kit can provide extra weatherproofing and extend the life of the garage. Here’s a comparison of roof styles:

5. Interior Customization

Plywood sheets, shelving, and custom storage spaces can enhance the interior. For those planning a workshop, consider additional shelves, hooks, and insulation for all-weather comfort. Make sure to use weather-resistant materials.

Many DIYers find Home Depot to be a convenient source for materials like insulation and plywood sheets.

6. Final Adjustments and Inspections

Add exterior paint or sealants to enhance longevity. Consider adding vents, windows, or a simple ventilation system to prevent overheating. Once completed, inspect all welds, anchor points, and the roof to ensure everything is secure.
