Do you need planning permission for a bungalow rear extension in Llantwit Major?
Here is how the rules in Wales apply to a bungalow rear extension in Llantwit Major.
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. 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 Llantwit Major like to extend?
Older terraces near the centre and post-war semis further out are typical of Llantwit Major. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Bungalow rear extension questions in Llantwit Major
Do you handle building control in Llantwit Major?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
Can you match the brick or stone on my Llantwit Major house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Will the roof look odd?
Not if the pitch and tiles match. Where the eaves are low, a flat-roofed section with a lantern is an alternative.
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 get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
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.
