Glazed rear extension in Walkden

How much does a glazed rear extension cost in Walkden?

A glazed rear extension in Walkden is priced at £2,630–£4,510 per square metre including VAT as a guide, before kitchen fit-out and fees. North West prices sit below our West Midlands baseline; access on terraced streets 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 glazed rear extension in Walkden?

Here is how the rules in England apply to a glazed rear extension in Walkden.

Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is 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 Walkden like to extend?

Stone and brick terraces are common around Walkden. Where houses back onto a ginnel or alley, deliveries can come in from the rear, which makes the build tidier.
