Do you need planning permission for a bungalow rear extension in Monmouth?
The planning route for a bungalow rear extension in Monmouth is set by Wales's householder rules and your council.
In Wales a single-storey rear extension can often be permitted development if it projects no more than 4 metres beyond the rear wall and is no more than 4 metres high. Wales has no prior approval route for deeper extensions, so anything bigger needs a householder planning application.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.
What are homes in Monmouth like to extend?
Older terraces near the centre and post-war semis further out are typical of Monmouth. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Bungalow rear extension questions in Monmouth
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.
Do you handle building control in Monmouth?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
Do I need to move out?
Rarely; the opening into the bungalow is made late in the build.
How long does a rear extension take to build in Monmouth?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
Is the site visit in Monmouth free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
