The basics of planning permissions for outbuildings

Before we get into the basics of planning permissions for garden buildings, you need to first understand what is meant by ‘outbuildings’.

What counts as an outbuilding?

Studio combi buildingThe rules concerning outbuildings apply to:

  • sheds
  • garages
  • ancillary garden buildings e.g. workshops, offices, garden studios
  • and many other kinds of structures for a purpose incidental to the enjoyment of the dwelling house.

Under the current regulations, outbuildings are considered to be permitted development, meaning they don’t require planning permission. That is provided all the following conditions are met:

1. Principle elevation

Outbuildings are not permitted on land that is forward of the principal elevation of the original house.

2. Height limits

Outbuildings and garages must be single-storey with a maximum eaves height of 2.5 metres.  With a maximum overall height of 4 metres with a dual-pitched roof, or 3 metres for any other roof.

3. Near boundaries

If the outbuilding is within 2 metres of the property’s boundary, the whole building should not exceed 2.5 metres in height.

4. Area permitted

Outbuildings and other additions must not exceed 50% of the total area of land around the ‘original house’. Sheds and all other outbuildings and extensions to the original house must be included when calculating this 50% limit.

What is meant by the term ‘original house’?

The term “original house” means the house as it was first built. Or as it stood on the 1st of July 1948 (if it was built before that date). This is because although you may not have built an extension to the house, a previous owner may have.

In National Parks, the Broads, Areas of Outstanding Natural Beauty (AONB), and World Heritage Sites the maximum area to be covered by any outbuilding that is more than 20 metres from the house must not exceed 10 square metres.

Buildings at the side of properties in the above AONBs will also need planning permission. If you have a listed building, then any outbuilding will require planning permission.
