Do I need planning permission?

The answer the question (do I need planning permission?) depends on a number of things but our customers can rest assured that we undertake to sort all the planning issues out for you. We have been working closely with local government and borough councils for long enough to have a very good understanding of building control regulations and can confidently take on the responsibility of processing your application so that you don’t have to.


In brief, planning permission is not required providing:

  • You do not build between the “original house” and any highway, unless the highway is at least 20 metres from the proposed structure.
  • You do not build over more than half the garden area.
  • The proposed structure is not bigger than the highest part of the house roof.
  • The proposed structure is not more than 4 metres high and within 2 metres of the boundary.
  • You do not increase the volume of the original house by more than; 50 cubic metres, for a terraced house or a house in a conservation Area or; 70 cubic metres for any other property.

It is important to note the following:

  • If any of the buildings are more than 10 cubic metres in volume and within 5 metres of the house, they count against the cubic meter allowance.
  • In a Conservation Area you count all the buildings more than 10 cubic metres in volume against the allowance, wherever they are on the property.
  • Attached garages, carports, extensions, conservatories, swimming pools and utility rooms are all classed as extensions.
