As simple, self-contained units capable of incredible versatility, shipping container popularity is on the rise – especially when used for container conversions.
But what size is best for you?
Read our handy guide, which covers the size of each container type and just a few of the possible uses you could consider for your shipping container conversion.
What size shipping containers are the most common?
The most common ISO shipping containers on the market are usually either 10, 20, or 40-foot containers, but a smaller 8-foot container is also available for those pushed for space.
And in case you are having trouble imagining a cubic foot (who isn’t?!), consider a box that has a width, length, and height, each roughly the length of your forearm – that’s around a cubic foot.

What can I use a converted shipping container for?
Most containers can be used for overseas shipping for around 35 to 40 years with proper maintenance, including rust removal and repainting with marine-grade paint to keep them ship-shape.
However, once they reach the end of their lives travelling across the seas, shipping containers can be converted for many, varied purposes – limited only by your imagination.
With a range of customisation options, including adding windows, doors, internal features such as shelves, or adding services including water, gas, and electricity, a shipping container can be anything you want it to be.
8-foot container conversion ideas
- Personal storage
Ideal for storing overflow personal items you want to keep but don’t need at hand, like out-of-season clothes, holiday essentials, or family heirlooms.
- Compact garden storage
A more compact option that can fit into your garden’s nooks and crannies, perfect for storing a lawn mower, gardening equipment, or even outdoor furniture.
- A mini-office or workstation
Maybe you only work from home part-time, or you don’t need space for clients or filing cabinets? If this is the case, a mini-office in your garden could be just the bit of headspace you need.
- Equipment storage
Hobbies and the children’s extracurricular activities can generate lots of equipment, including sporting equipment, golf clubs, a bicycle or two, or even construction equipment.
- Motorcycle housing
Are you a biker looking to store your bike while protecting it safely and securely from theft and the elements? Consider a motorbike storage container!
- Mobile kiosks or ticket booths
Once modified, an 8-foot container can make an excellent mobile kiosk or ticket booth for fairs and events, or concessions, merchandising, and ticket sales at outdoor events.
- Retail displays or pop-up shops
With eye-catching modification and design, an 8-foot container can be all you need to draw in customers and sell your specially curated selection of goods.
10-foot container conversion ideas

If you craft or manufacture goods for a living, an external workshop will be essential. A 10-foot container will give you plenty of space for workbenches, tool storage, and open spaces to measure and cut raw materials.
- Small business storage
Ideal for keeping stock safe from criminals and damage from the weather, a 10-foot container is plenty of space for excess or overflow seasonal stock before you put it out for selling.
- Trade show booth
Sometimes referred to as an exhibition space, a 10-foot container is ideal for companies or individuals needing a trade show booth to increase their presence at professional marketing events.
With enough space for you to stand within and for visitors to walk around and exciting displays, you can show everyone what you can bring to the table.
- Small commercial properties
From coffee shops to farm shops, a 10-foot container gives enough space for a few customers, store staff and the equipment or stock you need to run the business.

For camping and caravan parks to open-air lidos and parks, a 10-foot container can give you enough space for a few cubicles and handwashing space.

Suitable for use for multiple staff, a shipping container office space can be customised in any number of ways to include storage options, branding, and a welcoming feel for visiting customers.

Our largest containers are ideal for storing inventory, equipment, or materials in a warehouse or industrial setting thanks to their security and weatherproofing.

In response to towering house and mortgage costs, many are now looking for alternatives to the traditional housing stock. A 40-foot container can provide ample room for a single inhabitant or a couple, giving them an alternative option with all the mod-cons they are used to.
