Planning and approvals in Newburn
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
The planning position for a specific Newburn address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Extensions in and around Newburn
We cover Newburn and the postcode districts NE5, NE15, NE21, NE40. The same team covers Gosforth (5 miles), Newcastle upon Tyne (5 miles), Gateshead (6 miles), Felling (7 miles), all within easy reach.
Stanley, in County Durham, is roughly 8 miles from Newburn and also on our list. Across the North East, houses often have rear yards or modest gardens, so compact, well-lit single-storey extensions make the biggest difference.

Your questions about a wraparound extension in Newburn
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Newburn, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Newburn?
Yes. We cover Newburn and the surrounding parts of Tyne and Wear. Site visits are free and there is no obligation.
Do I need building regulations approval in Newburn?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
Will I need to move a drain?
Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.
