Glazed rear extension in Bridgend
For homes in Bridgend, 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.
Bridgend and its postcode districts CF31 and CF35 are part of our South Wales Valleys coverage. Glass-led rear extensions in Bridgend 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 Bridgend?
The planning route for a glazed rear extension in Bridgend 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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Bridgend like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Bridgend. Sloping sites are common, so floor levels and retaining walls are designed at the start.

Do I need a party wall agreement?
In Wales, usually yes if the extension is on or near a shared boundary or close to a neighbour's foundations. We serve the notices.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
