Bungalow rear extension in Clevedon

How much does a bungalow rear extension cost in Clevedon?

In Clevedon, our guide for a bungalow rear extension is £1,920–£3,120 per square metre including VAT for a standard specification. South West prices run slightly above our West Midlands baseline; natural stone to match the house is the main variable.

Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.

Do you need planning permission for a bungalow rear extension in Clevedon?

Here is how the rules in England apply to a bungalow rear extension in Clevedon.

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.

If 3 or 4 metres is not enough, England's prior approval route allows 6 metres on a terraced or semi-detached house and 8 metres on a detached house for a single-storey rear extension. Neighbours are consulted, the council decides within 42 days, and the fee is £249, rising to £310 from 8 December 2026.

Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.

What are homes in Clevedon like to extend?

Stone-built and rendered houses are common around Clevedon, so matching the walling is a design decision in its own right: natural stone, reconstituted stone or a render finish across old and new.
