The planning rules for porches are applicable to any external door to the dwellinghouse.
Adding a porch to any external door of your house is considered to be permitted development, not requiring an application for planning permission, provided:
- the ground floor area (measured externally) would not exceed three square metres.
- no part would be more than three metres above ground level (height needs to be measured in the same way as for a house extension).
- no part of the porch would be within two metres of any boundary of the dwellinghouse and the highway.
Please note: The permitted development allowances described here apply to houses and not to:
- Flats and maisonettes (view our guidance on flats and maisonettes)
- Converted houses or houses created through the permitted development rights to change use (as detailed in our change of use section)
- Other buildings
- Areas where there may be a planning condition, Article 4 Direction or other restriction that limits permitted development rights.
