Terraced house rear extension in Durham

We plan and build rear extensions for terraced houses for homeowners in Durham. Rear and side return extensions for terraces, with access through the house and two neighbours. Start with a free site visit, then a written price once the design is agreed.

We cover Durham (DH1) as part of our County Durham work. Terraced streets make up much of the housing in parts of County Durham, and most rear extensions here go in without side access.

Do you need planning permission for a terraced house rear extension in Durham?

Planning for a terraced house rear extension in Durham follows the English householder rules.

Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.

The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.

What are homes in Durham like to extend?

Terraces and semis are typical around Durham. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.
