Do Loft Conversions require Planning Permission?

Planning PermissionPosted by Mark English Architecture Wed, June 26, 2013 15:45:04
Question: Do Loft Conversions require Planning Permission?

Answer 1:
No Planning Permission is Required - if the loft coversion only has roof window - VELUX Windows

Answer 2:
No Planning Permission is Required - if the loft coversion proposaln has REAR FACING dormer window(s) and/or Velux Windows, HOWEVER, this is only the case where Permitted Development Rights (PD Rights) are in place.

To be permitted development any additional roof space created by dormers must not exceed these volume allowances:

* 40 cubic metres for terraced houses.

* 50 cubic metres for detached and semi-detached houses.

If Permitted Development Rights have been removed - then a Planning Application WILL BE required.

You can check your PD Rights by contacting the Local Authority Planning Department.

Where work is proposed to a listed building, listed building consent may be required. The permitted development allowances described apply to houses not flats, maisonettes or other buildings.

Please note: In any event if the loft conversion is to be a habital space it is essential that a Building Regulation Application is submitted to Building Control with details of insulation, structural engineering and other technical requirements.

Answer 3: Planning Permission IS Required - If the loft conversion proposal has front facing dormer windows.

Velux Cabrio Windows are a great alternative to a front facing dormer window - and they don't require planning approval - if PD Right are in place on the property.

Further info can be found on the Planning Portal - Loft Conversions
