Anyone needing extra storage or workspace faces a choice: install a shipping container, or build a steel building or shed. Both solutions have their place, but the costs and ease of use differ considerably. In this article, we compare shipping containers and steel buildings on purchase cost, build time, maintenance and annual running costs.
A shipping container is a ready-made, movable steel space that leaves the factory or depot already wind and watertight. A steel building or shed, on the other hand, is constructed on site: first the foundations, then the steel frame, cladding and roof. This difference in approach immediately explains most of the cost difference. With a container, you pay for a finished product that is simply delivered and positioned. With a building, you pay for groundworks, materials, labour, and often an architect or structural engineer for the planning application.
In terms of size, shipping containers are available as standard in 10ft (around 3 metres), 20ft (around 6 metres), 40ft (around 12 metres) and 45ft (around 13.7 metres). For extra headroom, there's the High Cube version, 30 centimetres taller than standard with an internal height of 2.70 metres. A steel building is, in principle, unlimited in length and width, which is a genuine advantage once you go beyond a few hundred square metres.
The question "how much does a shipping container cost" can't be captured in a single figure, since it depends on size, new or used condition, and any modifications. For a specific price based on your situation, request a quote via the shop or the contact form; on working days, you'll usually receive a reply within an hour with price, stock availability and delivery date. What we can say is this: a container is a one-off purchase with no separate foundation costs, whereas a steel building always consists of multiple cost items that add up.
For a steel building, you need to budget for at least these items: groundworks and foundations, the steel frame itself, roofing and cladding, any insulation, doors and window frames, and the cost of a structural engineer or architect for the planning application. Taken together, these items often make a steel building more expensive per square metre than a container, especially for smaller floor areas, where the fixed costs (foundations, permits) weigh more heavily per square metre.
A shipping container is cheaper than building a shed as soon as you're looking at temporary or medium-term storage needs, fast availability and a limited footprint. Think of material storage on a construction site, extra workspace behind commercial premises, or private storage in the garden. In these cases, the fixed costs of a shed (foundations, permits, build time) weigh heavily, whereas a container can, in principle, be in place within 3 to 7 working days, exactly where you want it, provided the ground is reasonably flat and firm and the location is accessible for a lorry with a crane or sideloader.
A steel building becomes more attractive once you structurally need a large number of square metres, for example for a farm with machinery or a commercial unit with office space. In that case, you spread the fixed costs over a larger area, and the price per square metre becomes more competitive. For smaller and medium-sized needs, a container, or a combination of several containers, usually remains the more cost-effective and faster route.
Building a steel building takes time: from design and planning application to foundation work and the actual construction, weeks to months can pass, depending on the local authority and the size of the project. A shipping container, as mentioned, is usually in place within 3 to 7 working days of ordering. Do note that rules can also apply to positioning a container, depending on the local authority and zoning regulations. Rules differ by local authority and country, so always check this locally. You can read more about this in our article on containers by region.
In terms of ease of use, a container also scores well: it can be relocated if circumstances change, expanded simply by adding a second container, and customised in our own workshop. Think of extra personnel doors, windows, ventilation louvres, electrics and lighting, a lock box against break-ins, insulation, and painting in any RAL colour. These modifications are carried out before delivery, so the container arrives ready for use. If you want to convert a container into a fully-fledged workspace, read more in our article on converting containers into an office, workshop or garage.
An untreated steel container provides hardly any insulation on its own: steel conducts heat and cold quickly. However, the shipping container's insulation value improves significantly once you opt for an insulated version, something that's applied in our own workshop. With insulation and, optionally, electrics and lighting, a container becomes suitable as a fully-fledged workspace, even in winter. A steel building has the same issue: without insulation, a building is also poorly suited as a comfortable workspace, and insulation is often a significant extra cost item for a building due to the larger surface area.
For pure storage with no occupancy function, insulation usually isn't necessary; a guaranteed wind and watertight used container (cargo-worthy or A-grade, CSC-certified) is already sufficient. New means one-trip: it has made exactly one sea voyage and is in near-new condition, which gives it a slightly different price point and appearance.
To really compare a shipping container with a steel building, it helps to look at annual costs rather than just the purchase price. For a container, this includes: the purchase or rental price, any modifications, and otherwise little maintenance, since steel is inherently durable. For a building, this includes: purchase including foundations and construction, annual maintenance of the roof and cladding, possible repairs, and sometimes a higher insurance premium due to the permanent nature of the structure.
An indicative comparison of the main cost items:
| Aspect | Shipping container | Steel building |
|---|---|---|
| Purchase/build costs | One-off, no foundations needed | Foundations, steel frame, cladding and roof |
| Build and delivery time | Usually 3 to 7 working days | Weeks to months |
| Permits | Depends on local authority, often simpler | Almost always a planning application process |
| Maintenance | Limited, steel is durable | Annual maintenance of roof/cladding |
| Flexibility | Movable and expandable | Fixed, not movable |
| Insulation | Optional to add | Often a substantial extra cost |
If you'd rather not buy straight away, you could also consider renting. Containers are available to rent from around €60 per month, depending on type and rental period, which is a handy interim solution if you're not yet sure whether the need is permanent. More details can be found in our article on renting a shipping container.
Whether you buy or rent, HEROX offers three payment options: pay in advance by bank transfer with a 5% discount, pay after delivery (see it first, then pay), or spread payments over up to 36 months via licensed European finance partners from around €60 per month. This makes the switch to a container financially manageable, without the risk of having to pay a stranger in full upfront. You can read more about buying safely in our article on buying a shipping container safely. Check current stock in the shop, or request a quote directly via the contact form with your preferred container type and delivery location.
For smaller and medium-sized needs up to a few dozen square metres, a shipping container is usually more cost-effective, since no foundations or lengthy construction process are needed. For large, permanent floor areas of hundreds of square metres, a steel building can ultimately become more competitive per square metre, as the fixed costs are then spread over a larger area.
A shipping container is usually delivered and positioned on site within 3 to 7 working days, using a crane lorry or sideloader, provided the ground is flat, firm and accessible for a lorry. A steel building often takes weeks to months, due to the planning application, foundation work and the construction itself.
An untreated container insulates poorly on its own, but insulation can be added in our own workshop, along with electrics and lighting. This makes the container suitable as a fully-fledged workspace. For pure storage with no occupancy function, insulation usually isn't necessary.
This differs by local authority and country, so always check locally before ordering or building. In general, the process for a container is simpler than for a steel building, since no foundations or structural building drawings are required, but we can't provide any guarantees on this.
Yes, containers are available to rent from around €60 per month, depending on type and rental period. This is a handy interim solution if your need for extra space is temporary, or if you want to try out a container first, before deciding to buy, to see whether it meets your expectations.
