Permitted Planning for Verandas & Glass Rooms

We’re often asked whether planning permission is required to install one of our structures. In most cases, providing the criteria shown below is adhered to, they fall under ‘Permitted Development’. However, if you live in a conservation area or a listed building, then you will require planning permission, likewise if you live in a flat or maisonette. If in doubt contact us and we will advise as appropriate.

Carport, Walkway, Veranda and Glass Rooms

  • Maximum depth of a single storey rear extension is 3.0metres for an attached house & 4.0 metres for a detached house.
  • Maximum width no greater than width of dwelling house.
  • No extension forward of the principal elevation or side elevation fronting a public highway. This means that any extension closer to the highway from the original house will require planning permission.
  • Side extensions to be single storey with maximum height of 4.0metres and width no more than half that of the original house.
  • Maximum eaves height within two metres of a boundary to be no greater than 3.0 metres.
  • No more than 50% of land around the ‘original house’ is covered by an extension.
