What to do if my shipping container gets damp should be a rare question. After all, shipping containers are built to carry goods safely across the world’s oceans, enduring extreme weather and rough handling whilst keeping their contents secure and shielded from the elements.
(more…)‘Can I bury a shipping container?’ is a question that pops up surprisingly often here at Upminster Containers. On paper, it sounds brilliant; purchase a ready-made steel box, dig a hole, drop it in, job done. However, in reality, burying a standard shipping container is rarely safe, unlikely to be compliant, and almost never as simple (or cost-effective) as it first appears.
In this blog, we’ll explain why we don’t recommend burying a container, what the structural and safety risks are, how planning and building regulations see it, and the practical alternatives that achieve the same goals without the inevitable pitfalls.
No, we do not advise that you bury a standard shipping container. Containers are engineered for transport and stacking via their corner posts, not to sit underground resisting soil pressure on the roof and walls.
Converting one into an underground room or bunker safely, requires a fully engineered underground structure (retaining walls, roof beams, waterproofing, drainage and ventilation) rather than relying on the container itself. British standards currently state that the roof is only able to support people working on it, not pressure from continual foot traffic, and soil loads are a different kettle of fish entirely.
Consider the intended use: Containers are designed to carry loads at the corners (for stacking) during transport. Their side and end walls are tested for specific, internally distributed loads that are based on the movement of a ship, i.e. the state that they are expected to be in; not the continuous pressure of compacted soil on top of it. Burying the container would introduce pressures that it wasn’t built to resist.
Corrosion moves quickly underground: Most shipping containers are made from Corton Steel, which is water resistant, but needs to dry between exposure to water. If your container is buried in soil or kept continuously damp, then corrosion is likely to set in sooner rather than later.
Confined space hazards: An underground container (even partially submerged) can become a confined space, with risks from reduced oxygen, toxic gases, and even fire. A properly submerged structure needs a strong source of ventilation and monitoring to ensure that it’s fully safe and compliant.
Structural collapse and water leaks: Backfilled soil would apply significant pressure to the walls and roof. Without engineered retaining structures, buckling or total collapse is a real risk, especially as the soil gets wetter. Even small leaks underground can lead to persistent damp, mould, damage to contents and serious physical injury.
Excavating and creating underground accommodation or storage is unlikely to be covered by simple permitted development and standard building regulations.
Whilst projects vary, it’s sensible to assume you’ll need quite extensive planning approval for any buried or semi-buried space. Your local authority can advise on your site, but expect this to be a lengthy endeavour and a costly project once approved.
If you’re set on an underground structure, and they do have their uses, such as temperature stability, aesthetic purposes, and low profile for storage, then the safe route is to work with a specialised engineer to create what you need.
This would include:
There are several other ways to reach a similar goal; you can still achieve discretion, thermal regulation and weather protection without putting a standard container into the ground.
Part-submerged installation: Place the container on a suitable base (more on this here), then build retaining walls to either side and backfill against the walls, not against the container. You can then work with your engineer to create a roof or canopy rather than adding heavy soil onto it. With any projects involving significant groundworks, we would still also highly recommend working with an engineer rather than attempting this yourself.
Discreet siting and screening: Position the container below fence lines and add timber cladding, trellis, or artificial plants. It will be a much more discreet addition, without the need for excavation and with far fewer regulatory and planning issues.
Air conditioning upgrades: If the aim is temperature stability, then you can add insulation, controlled ventilation (included as standard with Upminster Containers) and (if needed) a dehumidifier.
Modular buildings: For high-spec spaces or if you would like to make it habitable, consider our modular buildings, which are designed for quick installation and year-round comfort; and most importantly, avoid the stress of extensive groundworks.
So, if you’re wondering ‘Can I bury a shipping container?’, the practical and safe answer is: Don’t bury a standard unit. Containers aren’t designed for the pressure of compacted earth, corrosion from underground damp, and you’ll also face significant safety hurdles. If you need a low-profile, discreet or highly protected space, there are better-engineered alternatives, and plenty of above-ground solutions that deliver the outcome that you want with far less risk.
We have supplied and adapted containers for secure storage, workshops, offices and more since the 1950s. Upminster Containers offers practical options that deliver the performance most people hope to get from a buried structure, minus the risk:

Whether you’re running a business from home or simply looking for extra storage space; a shipping container can be a secure, and cost-effective solution. However, before you arrange a delivery there’s one big question people often ask us here at Upminster Containers:
‘Can I put a shipping container on private land?’
The short answer is yes, in most cases you can, but there are some considerations you’ll want to keep in mind. In this blog, we’ll cover everything you need to know before putting a shipping container on your property, from permissions, to site preparation and setup tips.
Shipping containers are no longer just for shipping. Their solid steel construction and weather resistance make them a go-to option for many. At Upminster Containers, we work with customers across the Southeast who need secure storage or a working space right where they live. A shipping container is often the perfect fit for:
Need extra room for tools or a dedicated place for your projects? A 20ft-40ft container can easily become a fully kitted-out DIY space; lockable, weatherproof, and right where you need it.
Working from home and need more room? Converted containers make excellent garden offices, complete with insulation, electrics and windows. Just note: once converted, you’ll likely need planning permission.
A container on your driveway or property is ideal for safely storing furniture, tools and appliances during a renovation or move. Quick to deliver and easy to remove once the job’s done.
Let’s get into the most important bit: planning permission.
The good news is if you’re placing a shipping container on your own private land and using it for storage or non-commercial personal use, in many cases you won’t need planning permission, especially if it’s not permanently fixed and doesn’t significantly alter the appearance of the site. As always though, it’s best to check with your local planning office at the council before placing your container. A quick call can save a lot of future hassle.
There are a few notable exceptions where permission may be required, for example:
You probably will need planning permission if:
One factor that makes a difference in planning law is whether your shipping container is considered temporary or permanent.
Even if it’s technically a temporary structure, some councils may still require notification or planning, depending on your location and use case.
Planning permission aside, there are a few key things to think about before putting a container on your land:
Make sure a delivery truck can reach your site safely. We’ll assess access as part of your initial consultation, but you’ll want to consider gate width, turning circles, overhead wires, and driveway strength.
Although containers can be placed directly on firm ground or gravel, we recommend using timber sleepers, concrete pads, or a level hardstanding for best stability and to prevent moisture issues.
If you’re storing items sensitive to moisture (furniture, paperwork, electronics), talk to us about ventilation and anti-condensation treatments. Good drainage around the base is also essential.
Even if planning permission isn’t required, it’s still a good idea to let your neighbours know you’re installing a shipping container. If it’s visible from their property or placed close to a shared boundary, a friendly heads-up can go a long way.
You may also want to consider painting or cladding your container to make it more visually appealing if it’s staying long-term.
We’ve been helping customers with container storage solutions for over 50 years, delivering to homes, farms, worksites and businesses across Essex, London and the Southeast. Whether you need a simple storage unit or a custom container setup, we’ll help you find the perfect fit for your private land.
When you work with Upminster Containers, you get:
So, can you put a shipping container on private land? In most cases, yes. Especially for simple storage or short-term use, planning permission usually isn’t required.
But if your container is staying long-term, getting converted, or going in a sensitive area, it’s always wise to check with your local council. A bit of planning upfront can save you headaches later on.
