Do you need planning permission for a two-storey rear extension in Bromsgrove?
The planning route for a two-storey rear extension in Bromsgrove is set by England's householder rules and your council.
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. 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 Bromsgrove like to extend?
Red-brick terraces and 1930s semis make up much of Bromsgrove. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.

FAQ
Two-storey rear extension questions in Bromsgrove
How long does a rear extension take to build in Bromsgrove?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
What postcode areas do you cover around Bromsgrove?
Including B60 and B61, and the surrounding Worcestershire area.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
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.
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.
Is the site visit in Bromsgrove free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
