FAQ about planning permissions and building regulations

We often get questions regarding the nature of planning permissions and their role in loft conversions and building extensions. Modern Attics thought it would be wise to create a guide on the blog to explaining some of the more specifics. So the essential question is; do you need permission to convert my loft into a room or to construct a dormer roof extension?

In terms of Building Regulation Approval the answer is yes. This is mainly due to the complex nature of fire regulations today. The best course of action is to consult a building control surveyor on the specifics of your conversion. You are able to submit your plans to them as well if you already have had something drawn up.

In terms of Planning Permission, when it comes to roof additions and alterations and you are located in a conservation area then you will again require planning permission.

If you are only planning internal works then you wouldn’t need planning consent unless you live in a Listed Building. If you live in a ListedBuilding, you will need listed building consent for any significant works whether internal or external.

Planning permissions will need to be acquired under the following circumstances if you are having alterations or additions made to the roof:

  • If any part of the house would exceed the highest part of the existing house roof
  • If any part of the house would extend beyond the plane of any existing roof slope
  • If the roof space would exceed that of the original roof space by more than: (40 cubic metres on a terraced house or 50 cubic metres on any other house)
  • If the works include the construction of a balcony or raised platforms
  • If the works include the installation, alteration or replacement of a chimney or vent pipe.
  • If more than 50% of the land surrounding the original house was covered with buildings.
  • If the enlarged/extended part of the house would be located within 2 metres of the property boundary and the height of the eaves of the enlarged/extended part exceeds 3 metres.
  • If the extension includes the installation, alteration or replacement of microwave antenna.

Development will be permitted under the following conditions:

  • The building materials for the external construction should be of similar appearance to those of the existing dwelling materials
  • The edge of the enlargement closest to the eaves of the original roof should not be less than 20cm from the eaves of the original roof.
  • Any windows inserted in the wall or roof slope forming a side elevation of the dwelling shall be obscured-glazed and non-opening

Planning permission can be required if the permitted development rights for your property have been removed.

These are just some of the essential reasons for planning permissions involving loft conversions. Many times it is not required. It all depends on your property type, it’s location and your plans for it. For more information on planning permissions and loft conversions please Contact Us at Modern Attics.
