Glazed rear extension in Porthcawl
For homes in Porthcawl, 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.
Porthcawl is covered from our South Wales Valleys round, including CF36. Glass-led rear extensions in Porthcawl 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 Porthcawl?
Here is how the rules in Wales apply to a glazed rear extension in Porthcawl.
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 Porthcawl like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Porthcawl. Sloping sites are common, so floor levels and retaining walls are designed at the start.
