Do you need planning permission for a glazed rear extension in Brymbo?
Planning for a glazed rear extension in Brymbo follows the Welsh householder rules.
In Wales a single-storey rear extension can often be permitted development if it projects no more than 4 metres beyond the rear wall and is no more than 4 metres high. Wales has no prior approval route for deeper extensions, so anything bigger needs a householder planning application.
Wales has its own Approved Document L, with targets for walls, roofs, floors and glazing similar to but not identical with England's. Heavily glazed designs are checked with a calculation.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Brymbo like to extend?
Brymbo has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.

FAQ
Glazed rear extension questions in Brymbo
Do you handle building control in Brymbo?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
How much does a glazed rear extension cost in Brymbo?
As a guide, £2,600–£4,460 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £31,000–£53,500 at that rate. Your written price follows the survey.
Is a glass box a conservatory?
No. It is built to Building Regulations as part of the house, with insulated floor and roof, so it is usable all year.
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.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
