Whether you want to securely store power tools, your motorcycle, or want to make it into a livable space, this article tells you everything you need to know about shipping container sheds plus some great ideas to get started.

Do Shipping Containers Make Good Sheds?

Shipping containers make extremely durable and watertight sheds because they are made of weathering steel called COR-TEN steel which is more resistant to atmospheric corrosion than regular steel. They securely store tools, heavy equipment, automobiles, and motorcycles.

Durable and Strong

Durability and strong construction put shipping containers at a major advantage over sheds. They are designed to keep cargo safe and secure even though traveling overseas with harsh weather and salty air. To do this, they are constructed with very strong steel and industrial rust-resistant paint.

Storage containers are durable because they’re made of COR-TEN steel. This is a 14-gauge steel alloy that is then painted with high-quality industrial paint to protect it from rusting. The undercarriage is sprayed with an industrial coating similar to an automobile’s undercoating which also makes it resistant to rust.

The 1″ thick floors are treated with marine grade plywood and “C” channel cross members. This means they are very sturdy and will hold more weight than regular sheds.

To break into a storage container shed, a thief would need power tools and a lot of time. Stealing from a regular shed only takes a crowbar, hammer, and a few seconds. Storage container sheds are a stronger and more secure place to keep your expensive tools, heavy equipment, cars, and motorcycles.

Resistant to Rodents and Pests

Shipping containers are naturally resistant to rodents and pests. The double-gasketed doors form an extremely tight seal against mice, insects, and moisture.

Higher Walls and Doors

The “high cube” design of a shipping container gives you more vertical space for storage. A container is 8.5 feet tall with 7’9″ of wall height and a shed averages 6’3″ of wall height. Plus the door opening is much larger than a shed. A shipping container door opens up to 7’8″ wide x 7’5″ high.

Is it Cheaper to Build a Shed or Buy a Shipping Container?

It is cheaper to buy a shipping container than build a shed. The average 6′ x 9′ shed costs $3000 – $5,000 and the average used 8′ x 20′ shipping container costs $1,200 – $2,600 and new 8′ x 20′ shipping container costs $2,550 – $5,800. Add another $120-180 per square foot to convert into a livable space.

You may see used sheds on Facebook Marketplace or Ebay for cheap, but buying a used shed has it’s downsides that used shipping containers don’t.

Sheds are not as durable as containers and once they’re owned by someone else begin to degrade. The location they’re stored in affects how much moisture they’re exposed to and if insects or rodents invade the shed.

How Much Does a Shipping Container Shed Cost?

Shipping Container Bunker

For years, a popular choice among preppers and survivalists are metal shipping containers to use as a backyard bunker. It seems pretty easy to buy a shipping container, place in the backyard, and have a nice 8′ x 20′ space to build out into a bunker. But because the walls are just 0.075-inch corrugated sheet steel panels they are too thin to protect against bullets or blasts and overtime.

If you put it underground, not only would you have to dig a huge hole, you’d have to worry about it getting water corrosion and the thin roof collapsing under the weight of soil on top of it. So, for a bunker, it’s not the best idea.

Does a 20ft Container Need Planning Permission?

A 20ft container usually requires planning permission for most States in the United States. The permit is usually very basic and easy to complete. There may be restrictions on the location, proximity to neighbors, height, length of stay,  and appearance of the storage container.    

Most counties require some sort of paperwork to place a shipping container on your land, and if you have a HOA, you can bet that they have some rules, too. Generally, if you can keep the container away from the neighbors, it looks nice, and it’s away from the street, you should be able to get permission.

What Do You Put Under a Shipping Container?

The ground under a shipping container shed needs to be even, flat and dry. Follow these guidelines to decide if you need to build a foundation or put it on a gravel pad or trailer.

A single shipping container can be placed on even dry land for up to 1 year without anything under it. If the ground is uneven or wet, it is a multi-container structure, or it will be placed longer than 1 year, put a gravel pad, trailer, or foundation under it to prevent it from sinking.

Keep It Elevated

When putting the container on bare dirt, asphalt, or crushed stone, put pressure treated 6′ x 6′ x 8′ timbers along the front and back. This will keep it up off the ground and reduce the amount of maintenance it needs later.

Put crushed stone on the ground instead of just bare dirt to allow water to drain underneath the container to prevent, or delay, rusting.

Even Ground

If the ground is uneven you may need to hire a professional to level the ground, or rent the equipment yourself. Any rocks, plants, and debris need to be cleared, too. Check for gaps or holes which may fill with water and attract insects causing infestations and rust.


The most common types of foundation for a shipping container is a concrete slab, sand Crete, pile foundation.
