Do you need planning permission for a glazed rear extension in Ebbw Vale?
Here is how the rules in Wales apply to a glazed rear extension in Ebbw Vale.
Welsh permitted development allows a single-storey rear extension of up to 4 metres in depth and 4 metres in height, subject to boundary and garden-coverage limits. There is no larger-extension prior approval scheme in Wales.
Wales has its own Approved Document L, with targets for walls, roofs, floors and glazing similar to but not identical with England's. Heavily glazed designs are checked with a calculation.
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 Ebbw Vale like to extend?
Ebbw Vale is largely terraced streets on sloping ground, where back gardens step up or down from the house. Excavation, retaining walls and drainage are priced at the survey.

FAQ
Glazed rear extension questions in Ebbw Vale
How long does a rear extension take to build in Ebbw Vale?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can you match the brick or stone on my Ebbw Vale house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Is a glass box a conservatory?
No. It is built to Building Regulations as part of the house, with insulated floor and roof, so it is usable all year.
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 I need planning permission for a rear extension in Ebbw Vale?
Often not for a single-storey rear extension of up to 4 metres under Welsh permitted development. Wales has no prior approval route for deeper extensions.
Do you handle building control in Ebbw Vale?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
