Shipping Container Planning Permission

When placing a shipping container on your land requires planning permission, and the rules for using containers as storage, offices, or living accommodation.

Shipping containers are increasingly popular for garden storage, home offices, workshops, and even living spaces. But unlike a garden shed, a shipping container is a large, industrial structure - and the planning rules treat it differently depending on how and where you use it.

Residential Garden Use

A shipping container placed in a residential garden is assessed against the same permitted development rules for outbuildings. To avoid needing planning permission, it must:

Be single storey with a maximum eaves height of 2.5 metres (if within 2 metres of a boundary)
Not exceed 4 metres in height if it has a dual-pitched roof, or 3 metres otherwise
Not cover more than 50% of the garden area
Be used for purposes incidental to the enjoyment of the house - storage, a hobby room, a home gym, or a garden office for your own use
Not be used as self-contained living accommodation (no bedroom, bathroom, or kitchen that would make it a separate dwelling)
Not be placed forward of the principal elevation (front of the house)

A standard 20ft shipping container (6m x 2.4m x 2.6m) can fit within these limits. A 40ft container (12m x 2.4m x 2.6m) also fits the height limits but takes up significantly more garden space.

The Problem: Character and Appearance

Even if a container technically fits within PD size limits, councils sometimes argue that a shipping container is not genuinely "incidental" to residential use because of its industrial appearance. This is a grey area - there is no specific rule against containers, but enforcement officers may take a different view from a standard timber shed.

To reduce risk:

Clad the container in timber or paint it to match the garden
Position it away from boundaries where it would be visible to neighbours
Keep it to a single container rather than stacking or joining multiple units

Agricultural Land

On agricultural land, shipping containers used for agricultural purposes (storing feed, machinery, tools) may be permitted under agricultural permitted development rights (Class Q, Part 6 of the GPDO). The rules depend on the size of the holding and the purpose.

However, placing containers on agricultural land for non-agricultural storage (e.g. renting them out as self-storage units) requires planning permission and may also require a change of use.

Commercial and Industrial Use

Using shipping containers for commercial purposes - self-storage businesses, retail pop-ups, offices, or workshops - almost always requires planning permission. This is a change of use of the land and the container itself constitutes operational development.

Living in a Shipping Container

Converting a shipping container into living accommodation (a "container home") requires full planning permission. It also requires building regulations approval covering:

Structural integrity and fire safety
Insulation and energy efficiency
Ventilation and damp proofing
Drainage and sanitation

Temporary Use

During building works, a shipping container used as temporary site storage is generally permitted for the duration of the construction project. Once the works are complete, it should be removed. If it remains permanently, it may need planning permission.

Conservation Areas and Designated Land

In conservation areas, national parks, AONBs, and World Heritage Sites, permitted development rights for outbuildings are more restricted. A shipping container is likely to need planning permission in these locations due to its visual impact on the character of the area.
