South Wales Valleys
Knocking through to a rear extension in the South Wales Valleys
Steel beams, padstones and props to open the back of the house safely. Rear extensions in the South Wales Valleys: we cover 27 towns including Rhondda, Tonypandy and Bridgend, with design, approvals and the build under one contract.
Older houses in the South Wales Valleys often have solid brick back walls carrying a lot of weight, so the steel design comes early. Stone terraces along the valley floors and post-war semis higher up are typical of the South Wales Valleys. Sloping sites are common, so floor levels and retaining walls are designed at the start.
What does it cost in the South Wales Valleys?
As a guide, £3,500–£9,000 including VAT. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
What approvals does it need in the South Wales Valleys?
Welsh building regulations apply to every rear extension. The council or a registered approver checks the work against the Welsh Approved Documents and issues a completion certificate.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent.

FAQ
Questions people ask
Can the whole back wall come out?
Often, with a beam across the full width or a goalpost frame. Some walls need a short pier left at the ends.
Do I need building control for a beam?
Yes. The calculations and the installed steel are checked.
How long does it take?
The wall itself usually comes out in a day or two, timed for when the extension is weathertight.
