Hartlepool and its postcode districts TS24, TS25 and TS26 are part of our County Durham coverage. In County Durham we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Hartlepool?
Planning for a two-storey rear extension in Hartlepool follows the English householder rules.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Hartlepool like to extend?
Brick terraces, colliery houses and post-war semis make up much of Hartlepool. Former mining areas often need a coal mining risk check before foundations are designed. In Hartlepool, a two-storey rear extension is worth comparing with the cost of moving once stamp duty, agents' and legal fees are counted.

FAQ
Two-storey rear extension questions in Hartlepool
Do I need planning permission for a rear extension in Hartlepool?
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.
Is the site visit in Hartlepool free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
What is the 45-degree rule?
Many councils check that a two-storey extension does not cross a 45-degree line drawn from the nearest habitable window of the neighbouring house. We test it at the first drawing.
How long does a rear extension take to build in Hartlepool?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do you handle building control in Hartlepool?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
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.
