Do you need planning permission for a glazed rear extension in Weston-super-Mare?
Here is how the rules in England apply to a glazed rear extension in Weston-super-Mare.
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 Weston-super-Mare like to extend?
Stone-built and rendered houses are common around Weston-super-Mare, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
