PPS 7 Addendum Residential Extensions and Alterations·Page 7·1.1
Introduction to Extensions and Alterations
Extensions and alterations are common domestic modifications. Small extensions or alterations to dwelling houses may be permitted development if specific requirements are met, but flats and properties in multiple occupancy do not benefit from permitted development rights.
Extensions or alterations are one of the most common changes made to our homes to cater for our changing domestic requirements. In some cases it is possible to carry out a small extension or make an alteration to a dwelling house without applying for planning permission, provided you meet specific requirements. This is known as 'permitted development' and more detailed information on this matter is set out in Annex B.
Please note that an extension to a flat or a residential property in multiple occupancy does not benefit from permitted development rights.
