Bungalow rear extension in Castleford

How much does a bungalow rear extension cost in Castleford?

Guide prices for a bungalow rear extension in Castleford start from our Yorkshire and the Humber rate of £1,720–£2,790 per square metre, including VAT. Yorkshire prices sit below our West Midlands baseline; matching natural stone is the main variable.

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 Castleford?

Planning for a bungalow rear extension in Castleford follows the English householder rules.

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. 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 Castleford like to extend?

Stone terraces and brick semis are typical of Castleford. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.
