Do you need planning permission for a glazed rear extension in Brierley Hill?
Whether your glazed rear extension in Brierley Hill needs a planning application depends on its size, your house and any local restrictions.
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 Brierley Hill like to extend?

How much does a glazed rear extension cost in Brierley Hill?
As a guide, £2,800–£4,800 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £33,500–£57,500 at that rate. Your written price follows the survey.

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Does glass need planning permission?
The same rules apply as any rear extension; glass does not change the depth or height limits.

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Is the site visit in Brierley Hill free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
