Loft Conversions Planning Permission

Planning permission is required when work  is carried out that can change the appearance or   size of  the original house structure. However not all changes to your house need planning permission. Most loft conversions are covered by the rights for 'Permitted Development'.

Loft Conversion Permitted Development

Not all properties are covered by the rules of permitted development. These can include Properties in heritage and conservation areas and areas of outstanding natural beauty.

Some houses have had their permitted development rights removed by their local authority. For more guidance call us or your local council to see if your loft conversion will be allowed under permitted development or if you need planning permission.

The rules for permitted development for loft conversions, are briefly set out below:

  • You cannot have any part of your dwelling exceed the height of the highest part of the existing roof.

  • No part of your dwelling can, as a result of the works, exceed beyond the plane of any existing roof slope that fronts a highway these include all public roads and most footpaths, bridleways and byways.

  • Your loft cannot expand your dwelling beyond 40 cubic metres in the case of a terraced house, or 50 cubic metres in any other case (eg semi-detached house).

If your planned loft conversion or house extension isn't covered by permitted development, you will need to apply to council for planning permission. CJM can guide you on this and oversee all applications to your local council on your behalf. Fees will apply which can vary depending on which local authority your application  falls in.

Lawful Development Certificates

To be certain that the existing use of a building is lawful for planning purposes or that your proposal does not require planning permission you can apply for a Lawful Development Certificate.

It is not compulsory to have an LDC but there may be times when you need one to confirm that the use, operation or activity named in it is lawful for planning control purposes.

Testimonials

"I deliberately kept quiet the fact that I am a chartered surveyor and monitored very closely the construction and finishes at every stage, and would like to say on behalf of myself and my wife how pleased we are with the final result. Great job well done guys!"

Bill


"I want to thank you and everyone at CJM for doing such a fantastic job on my loft conversion. As you know only too well, it was an extremely difficult and complex job, and I am in no doubt that no other loft conversion company could have pulled it off except CJM. Once again, thanks for doing a great job. You clearly put the customer first, and that kind of attitude is rare in the building industry."

Jane

"The quality of your work is first class. As you may remember, our son-in-law is a Professional Tiler. He helped us complete some of the decorating on our conversion. At ever stage that he made measurements to fit tiles, paper, etc. he found without exemption, all the walls, wood frames etc. to be true. He had never come across that in the last 10 years!!!     Thank you..
