Do I need Planning Permission for a loft conversion or extension?

Often a small extension or loft conversion will not require Planning Permission.

Permitted Development (PD) rights provide automatic planning permission for minor extensions, demolition and certain changes of use, such as a loft, garage or basement conversion.

However, PD doesn’t automatically apply. For instance, within Conservation Areas, listed buildings, flats, maisonettes or some areas of the country, known generally as ‘designated areas’, the PD rights are more restricted or don’t apply at all.

We will contact your local Planning Department for confirmation as Planning Laws do change and often there are local restrictions, generally titled Article 4 Land

When you come to sell your property, it may be prudent to have obtained a Lawful Development Certificate as proof that the works are under PD. This is a simple application to the Authority which we can handle for you.

When planning a more ambitious single storey extension, two storey extension or loft conversion with front dormer windows you will need planning permission if:

  • Your extension covers more than half the area of land surrounding your home
  • You are extending towards a road
  • You are increasing the overall height of the building
  • You are extending more than three metres from the rear of an attached house (STOP PRESS – this has now been increased to six metres until 30th May 2019)
  • You are extending more than four metres from the rear of a detached house. (STOP PRESS – this has now been increased to eight metres until 30th May 2019)
  • Your single-storey extension is taller than four metres
  • Your single-storey extension is more than half the width of your house
  • You are using materials that differ from the original style of the house
  • You plan on building a balcony or raised veranda

Unfortunately Planning Approvals cannot be guaranteed, but we will strive to work with you and the Planning Department to gain a favourable outcome.
