Glazed rear extension in Bideford
For homes in Bideford, 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.
Bideford is covered from our Devon round, including EX39. A wide sliding door with one long rooflight, rather than a fully glazed roof, keeps a glass-led extension usable in summer.

Do you need planning permission for a glazed rear extension in Bideford?
Here is how the rules in England apply to a glazed rear extension in Bideford.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
New fabric must meet Approved Document L (2021 edition incorporating 2023 amendments): walls 0.18, roof 0.15 and floor 0.18 W/m²K, windows 1.4 W/m²K or Band B. Under the simple route, new windows, doors and rooflights should not exceed 25% of the extension floor area plus any openings removed; more glass is possible with a whole-house calculation.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Bideford like to extend?
Stone-built and rendered houses are common around Bideford, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
