Planning Permission

Planning Permission Information - Conservatories

On 1 October 2008, new building regulations were introduced that state that adding a conservatory to your house is now considered to be a permitted development. Therefore, there is no need for the owner to apply for planning permission, subject to the following limits and conditions;

  • No more than half the area of land around the 'original house'* would be covered by additions or other buildings.
  • No extension forward of the principal elevation or side elevation fronting a highway.
  • No extension to be higher than the highest part of the roof.
  • Single-storey rear extension must not extend beyond the rear wall of the 'original house'* by more than three metres if an attached house or by four metres if a detached house.
  • Maximum height of a single-storey rear extension of four metres.
  • Maximum depth of a rear extension of more than one storey of three metres from the rear wall of the 'original house'* including ground floor.
  • Maximum eaves height of an extension within two metres of the boundary of three metres.
  • Maximum eaves and ridge height of extension are no higher than existing house.
  • Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.
  • Roof pitch of extensions higher than one storey to match existing house.
  • No verandas, balconies or raised platforms.
  • On designated land* no permitted development for rear extensions of more than one storey; no cladding of the exterior; no side extensions.

 

Planning Permission Information - Windows

Planning permission is not normally required for repairing, fitting or replacing doors and windows (including double glazing). However, if the building is listed or located in a conservation area (or other designated area) you should consult your local planning authority before any works are carried out. If you are a leaseholder, you too may need to get permission from your landlord or management company before proceeding.

 

Building Regulations

On the 1 April 2002, new building regulations were introduced that apply to all replacement glazing. The regulations concern the thermal performance and other areas such as safety, air supply, means of escape and ventilation.
