Bungalow rear extension in Thetford

How much does a bungalow rear extension cost in Thetford?

In Thetford, our guide for a bungalow rear extension is £1,960–£3,180 per square metre including VAT for a standard specification. East of England prices run slightly above our West Midlands baseline; clay soils near trees are the main foundation 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 Thetford?

The planning route for a bungalow rear extension in Thetford is set by England's householder rules and your council.

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.

England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.

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 Thetford like to extend?

Post-war semis and newer estates are typical of Thetford, and many have room for a full-width extension. Shrinkable clay is common in the East of England, so foundations near trees and hedges are designed to NHBC-style depth guidance.
