Do you need planning permission for a side return extension in Spennymoor?
Planning for a side return extension in Spennymoor follows the English householder rules.
Side return infills and the side leg of a wraparound are treated as side extensions in England: single-storey, no more than 4 metres high and no wider than half the original house. They are not permitted development in conservation areas, National Parks or National Landscapes, and a joined wraparound often needs a planning application because the side and rear rules apply together.
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 Spennymoor like to extend?
Brick terraces, colliery houses and post-war semis make up much of Spennymoor. Former mining areas often need a coal mining risk check before foundations are designed.

FAQ
Side return extension questions in Spennymoor
How much does a side return extension cost in Spennymoor?
As a guide, £2,070–£3,420 per square metre including VAT for a standard specification. For example, 2 m wide × 6 m deep (12 m²): about £25,000–£41,000 at that rate. Your written price follows the survey.
What postcode areas do you cover around Spennymoor?
Including DL16, and the surrounding County Durham area.
Glass roof or solid roof with rooflights?
A glass roof gives the most light; a solid roof with long rooflights is warmer and quieter in rain. Both work.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Do I need planning permission for a rear extension in Spennymoor?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
