Can I put a static caravan in my garden?

A second-hand static caravan can be bought for a few thousand pounds, which makes it a tempting answer to a lot of problems: a teenager who needs their own space, a parent moving in, somewhere to work, or a place to stay while the house is renovated. Whether you can put one in the garden comes down to three questions: is it a caravan in law, what will it be used for, and can you physically get it there.

Is it a caravan in law?

The legal definition matters because a caravan is treated as a chattel, a movable thing, rather than a building. The Caravan Sites and Control of Development Act 1960 defines a caravan as a structure designed or adapted for human habitation that can be moved from one place to another, whether towed or transported. The Caravan Sites Act 1968 added twin-unit caravans and set the maximum size: 20 metres long, 6.8 metres wide and 3.05 metres high internally, measured as set out in the Act. A standard single-unit static of 36 x 12 ft is well inside those limits; so are most twin-unit lodges.

Because a caravan is not a building, placing one in a garden is not “development” in the way that building an extension is. That is why planning permission is often not needed. But the use you put it to can still be development, and that is where people go wrong.

When you do not need planning permission

If the caravan is within the curtilage of your house, that is the garden and grounds that go with the home, and it is used for purposes incidental to the enjoyment of the house, planning permission is not normally required. Examples that are usually fine:

• a spare bedroom for family or guests, who use the kitchen and bathroom in the house or treat the caravan as part of the same household;
• a home office, studio, gym or games room;
• space for an elderly relative who lives as part of your household;
• somewhere to live for a limited period while the house is being renovated or rebuilt, where the caravan is clearly ancillary to the house.

You also do not need a caravan site licence in these cases. Schedule 1 of the 1960 Act exempts a caravan stationed within the curtilage of a dwellinghouse and used incidentally to it.

When you do need permission

• A separate home. If the caravan is lived in as a self-contained, independent household, with its own kitchen and bathroom and no real link to the main house, that is a change of use to a separate dwelling and needs planning permission. Councils refuse many of these in back gardens.
• Letting it out. A static caravan rented to a tenant, or let to holidaymakers, is not incidental to your house. It needs planning permission and, for holiday lets, may need a site licence too.
• Land that is not garden. A paddock, field or plot beyond the garden boundary is not curtilage. Stationing a caravan there is a change of use of the land and needs permission, except for very limited temporary uses.
• Designated land. In conservation areas, national parks and the curtilage of listed buildings, councils look more closely, and a caravan that is visible from the street can attract enforcement even where the use is incidental.

If you are not sure, ask the council for a Lawful Development Certificate. It costs a fee but it settles the question in writing.

The ten-year rule

People still talk about a four-year rule for building work without permission. For breaches that became substantially complete on or after 25 April 2024, the Levelling-up and Regeneration Act 2023 changed the enforcement time limit in England to ten years, as GOV.UK’s planning practice guidance explains. In other words, a caravan used as a separate dwelling without permission is now exposed to enforcement for a decade, not four years. Relying on the clock running out is a poor plan.

Getting it into the garden

This is the practical problem. A 12 ft wide caravan is roughly 3.7 metres wide and over 11 metres long. It arrives on a low loader and has to be winched or craned into position. Transport costs for a short local move typically start around £950 and rise with distance and width, and a crane lift adds £400 to £1,200; see how much it costs to move a static caravan. If the only route is over the house, you need a crane with the reach and a road closure permit. Measure the access before you buy the caravan, not after.

Once in place the caravan needs a level base, usually concrete pads or a hardstanding, mains electricity from the house through a proper external supply, water and drainage connections and, if you want gas, a bottled supply fitted by a Gas Safe engineer.

Decking around a caravan in a garden

Decking on a caravan in a garden follows the ordinary rules for garden decking rather than park rules. The Planning Portal explains that decking is normally permitted development if no part of it is more than 30 centimetres above the ground and, together with other outbuildings and extensions, it covers no more than half the garden. Decking at caravan floor level, which is usually 600 to 900 millimetres up, is above that limit, so a deck of the usual park type would need planning permission in a garden.

The way round it is a low deck at ground level with steps up to the caravan door, or a platform and steps rather than a full deck. Prices for the park-style alternative are on our caravan decking prices page if you are comparing, and static caravan decking explains the layouts.

Before you buy the caravan

1. Measure the access route, including gateposts, overhead cables and the turning circle for a low loader.
2. Decide what the caravan is for, and check it is incidental to the house rather than a separate home.
3. Check whether your house is in a conservation area or is listed.
4. Price the base, services and transport, which together often cost more than an older caravan.
5. Ask the council for a Lawful Development Certificate if there is any doubt.

If the caravan is going on a park instead, the rules are different and the park’s approval comes first: start with the postcode on the caravan decking installers homepage and we will find an installer who knows that park.
