Do I need planning permission to add a small wooden canopy over my front door?

Adding a porch canopy is classed as permitted development provided it meets the limits and conditions set out in legislation. Where this is the case, no application for planning permission is required.

Porches must meet the following limits:

  • the ground floor area (measured externally)would not exceed three square metres.
  • no part would be more than three metres aboveground 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.

Is planning permission or building regulations approval required to change to an electric garage door?

Changing a standard garage door to an electric garage door will not normally require planning permission. Instead, they are covered by permitted development rights.

Permission may be required if your property is listed, you live in a conservation area or there will be a visual impact on the appearance of the house as viewed from the street. If you are unsure, it is advised that you contact your local planning authority.
