Glazed rear extension in Briton Ferry
For homes in Briton Ferry, 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.
Briton Ferry and its postcode districts SA10, SA11 and SA12 are part of our Swansea Bay coverage. Glass-led rear extensions in Briton Ferry 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 Briton Ferry?
Planning for a glazed rear extension in Briton Ferry follows the Welsh householder rules.
In Wales a single-storey rear extension can often be permitted development if it projects no more than 4 metres beyond the rear wall and is no more than 4 metres high. Wales has no prior approval route for deeper extensions, so anything bigger needs a householder planning application.
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 Briton Ferry like to extend?
Older terraces near the centre and post-war semis further out are typical of Briton Ferry. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
