Conservatory (single storey)

Conservatories fall under the same planning regulations as any extension or addition to a house. This guide is for typical, single-storey conservatories*.

Adding a conservatory to a house is considered to be permitted development, not requiring an application for planning permission, provided these limits and conditions are met.

This mini-guide offers a visual walk-through of those limits and conditions.

*For information about extensions of more than one storey, see our mini-guide for two storey extensions.

Important note: The permitted development allowances described here apply to houses, not flats, maisonettes or other buildings. You should check with your Local Planning Authority whether permitted development rights apply – they may have been removed by what are known as Article 4 directions.
Other consents may be required if your house is listed or in a designated area.

When planning work you should read all the advice on the Planning Portal under ‘Your responsibilities – Other considerations before you start work’.
As well as other important information you will find guidance here on the permitted development regime.

Wales: This guidance relates to the planning regime for England. Policy in Wales may differ. Contact your local planning authority for further information.
