Glazed rear extension in Taunton
For homes in Taunton, 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.
Taunton and its postcode districts TA1 are part of our Somerset coverage. Glass-led rear extensions in Taunton 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 Taunton?
Whether your glazed rear extension in Taunton needs a planning application depends on its size, your house and any local restrictions.
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 Taunton like to extend?
Stone-built and rendered houses are common around Taunton, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.

Not if it is designed for its orientation, with solar-control glass, shading and ventilation.
