There are some scales of development to existing buildings which can legally go ahead without requiring planning permission. This type of building work is called “Permitted Development”.

 

Permitted development legislation has been put in place by the government to try and help reduce the number of applications for planning that local authorities have to deal with.

This covers;

– small extensions to existing buildings

– conservatories

– out buildings such as garages

– certain types of ‘change of use’ for buildings

– some types of conversions

 

 

There are guidelines which must be followed to ensure works fall within the permitted development remit. Some of these are outlined below for extensions and out buildings.

It is always a good idea to apply for a Lawful Building Certificate (LDC) when carrying out permitted development (PD) as this will guarantee that the works fall under the guide lines of PD. These can be especially useful if you ever plan to sell your home as they will provide evidence that the building works comply with current planning legislation. LDC’s can be applied for retrospectively so if you are sure that your work falls under PD then you can get to work as soon as you like – pending any neighbour notifications which may be required.

 

Extensions

  • 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.
  • These increased limits (between 3m and 6m and between 4m and 8m respectively) are subject to the neighbour consultation scheme.
  • Maximum height of a single-storey rear extension of four metres.
  • Extensions of more than one storey must not extend beyond the rear wall of the original house* by more than three metres.
  • Maximum eaves height of an extension within two metres of the boundary of three metres.
  • Maximum eaves and ridge height of extension 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.
  • Two-storey extensions no closer than seven metres to rear boundary.
  • Roof pitch of extensions higher than one storey to match existing house.
  • Materials to be similar in appearance to the existing house.
  • No verandas, balconies or raised platforms.
  • Upper-floor, side-facing windows to be obscure-glazed; any opening to be 1.7m above the floor.

 

Outbuildings/Garages

  • No outbuilding on land forward of a wall forming the principal elevation.
  • Outbuildings and garages to be single storey with maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof.
  • Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwelling house.
  • No verandas, balconies or raised platforms.
  • No more than half the area of land around the “original house” would be covered by additions or other buildings.
  • Within the curtilage of listed buildings any outbuilding will require planning permission

 

The National Planning Policy Framework was published on 27 March 2012 and sets out the Government’s planning policies for England and how these are expected to be applied.
