Glazed rear extension in Yeovil
Thinking about a glazed rear extension in Yeovil? Full-height glass, slim frames and big rooflights for the most open rear room. Our team handles the drawings, the planning route and the build, and your contract is with one company throughout.
Yeovil is covered from our Somerset round, including BA20 and BA21. 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 Yeovil?
Whether your glazed rear extension in Yeovil needs a planning application depends on its size, your house and any local restrictions.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres 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 Yeovil like to extend?
Stone-built and rendered houses are common around Yeovil, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
