Information to help you through the Planning process, for extensions and loft conversions.

Most properties have permitted development rights which means you can extend your property within certain limits without any further involvement from your planning department.

You are allowed to extend terrace dwellings by 50 cubic metres and semi detached dwellings by 70 cubic metres.

If you have already extended your property the volume must be deducted from your PDR, if you
back onto a highway you will require planning permission. We write to your local planning department on your behalf enclosing a detailed drawing of your proposal and requesting planning approval.
