Permitted development lets many houses extend, convert the loft or add an outbuilding without a full planning application. The rights are national, but the limits are detailed, they are measured against the original house rather than the one you see today, and they can be removed altogether.

Flats and maisonettes, newer estates with conditions on the original permission, and areas covered by an Article 4 direction all change what is allowed. The first job is to find out which rights the house actually has.

When the answer is yes, a lawful development certificate puts it on record. It is not compulsory, but it is the document a buyer's solicitor is likely to ask for when the house is sold.
