Do you need planning permission for a two-storey rear extension in Rawmarsh?
Planning for a two-storey rear extension in Rawmarsh follows the English householder rules.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Rawmarsh like to extend?
Stone terraces and brick semis are typical of Rawmarsh. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.

FAQ
Two-storey rear extension questions in Rawmarsh
How long does a rear extension take to build in Rawmarsh?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Is the site visit in Rawmarsh free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Will we need to move out?
Rarely. The first-floor opening is made late in the job and sealed with temporary screens.
Can you match the brick or stone on my Rawmarsh house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
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.
