Bungalow rear extension in Daventry

How much does a bungalow rear extension cost in Daventry?

In Daventry, our guide for a bungalow rear extension is £1,790–£2,910 per square metre including VAT for a standard specification. East Midlands prices sit a little below our West Midlands baseline.

We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.

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

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

In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part is 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. 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 Daventry like to extend?
