Glazed rear extension in Pontypridd
For homes in Pontypridd, a glazed rear extension is often the simplest way to gain space without moving. Full-height glass, slim frames and big rooflights for the most open rear room. We take it from survey to completion certificate.
We cover Pontypridd (CF37) as part of our South Wales Valleys work. Glass-led rear extensions in Pontypridd are planned around which way the garden faces, because that decides the glass specification.

Do you need planning permission for a glazed rear extension in Pontypridd?
The planning route for a glazed rear extension in Pontypridd is set by Wales's householder rules and your council.
The Welsh Government's householder rules let many homes add a single-storey rear extension up to 4 metres deep and 4 metres high without a planning application. Deeper projects go through a householder application, because Wales has no prior approval route.
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 Pontypridd like to extend?
Pontypridd 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 Pontypridd
How long does a rear extension take to build in Pontypridd?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do you handle building control in Pontypridd?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
Can I have a level threshold?
Yes, with a drainage channel outside the doors and the slab set to the patio level.
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.
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.
