Planning & Development Approval

In some instances planning approval is necessary if your property is listed and if a conservatory reaches a certain size.
However, if your conservatory or extension meets the conditions set out below, planning permission will not be required. This is called 'permitted development'. You will need planning permission if your 'permitted development' rights have been removed by a condition on a previous planning permit in the last 30 years or so planning permission is not required for a domestic conservatory or extension provided that:

  • the conservatory / extension is being built within your domestic curtilage, and (‘domestic curtilage’ is the area of land on which a dwelling house sits which is used for residential purposes.  It does not include a field or other open land next to a house, even if it is in the same ownership)
  • the external area of the structure is no greater than 30 square metres in total; if structures (including outbuildings and extensions to the house) have already been built as 'permitted development' (without the need for planning permission)since 1 June 2007, the combined total area of all structures must not exceed 30 square metres
  • the intended structure is not in front of a principal elevation of the house (‘principal elevation’ means any elevation or wall of a house that faces and is within 20 metres of a public road)
  • the conservatory / extension is not to be used for a commercial purpose and
  • the height of the conservatory / extension does not exceed 3.5 metres if the roof is pitched (in which case the bottom of the roof planes must not exceed 2.5 metres). This includes a part flat part pitched roof 
  • the height of the conservatory / extension does not exceed 2.75 metres if the roof is flat
  • the height of the conservatory / extension does not exceed 2 metres if it is within 1 metre of an adjoining property boundary
  • the conservatory / extension is accessible from the interior of the house 

What are the exceptions to the above?

You will need permission if:

  • any of the work involves the formation or alteration of vehicle access to a public road
  • any of the work creates an obstacle to a view of a public road or near a bend, corner or junction that would result in danger
  • your property is registered as a listed building or place (LBP) or a potential listed building or place (pLBP) and does not fall within an area of archaeological potential (AAP) 
  • your 'permitted development' rights have been removed by a condition on a previous Planning Permit in the last 30 years or so

 Building permission

You will normally require building permission if you want to build an extension to your home. However, extensions to a dwelling comprising of small conservatories, carports and entrance porches are exempt where they meet certain criteria.

 Conservatory (veranda or covered area)

You will not require building permission if:

  • a conservatory, which is attached to a dwelling, is separated from the dwelling by a wall, doors or windows that keep heat in the dwelling
  • it is has a internal floor of no more than 20 square metres
  • all low level glazing is safety glass 
  • it is constructed at ground level

Conservatories are not exempt if they will restrict ladder access to windows serving rooms in the roof or loft conversions, or first floor windows which are intended to help escape or rescue if there is a fire.
Any new structural opening between the conservatory and the existing house will require building bye-law approval, even if the conservatory itself is an exempt structure.

Porch

You will not require building permission if:

  • the structure is to be used for no other purpose 
  • it is not more than 5 square metres in floor area 
  • any glazing is safety glass

However, in the most part we design are conservatories so that they are exempt from building permission and sometimes planning permission when this is possible. However, this is not always possible particularly on the larger conservatories and orangeries. Our Sales Manager is fully competent on the planning and building laws and will advise you at the time of your visit if planning or building permission is necessary.
