West Wales
Roof lanterns and rooflights for rear extensions in West Wales
Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. Across West Wales we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Llanelli, Aberystwyth and Carmarthen.
Rear extensions in West Wales gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Older terraces near the centre and post-war semis further out are typical of West Wales. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
What does it cost in West Wales?
As a guide, £2,200–£4,500 including VAT. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
What approvals does it need in West Wales?
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.
