Wraparound extension in Newtown
An L-shaped extension that fills the side return and runs across the back. We design, get the approvals for and build wraparound extensions in Newtown and the surrounding area, with one contract from the first survey to building control sign-off.
Newtown and its postcode districts SY16 are part of our Mid Wales coverage. In Newtown we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

How much does a wraparound extension cost in Newtown?
A wraparound extension in Newtown is priced at £2,050–£3,350 per square metre including VAT as a guide, before kitchen fit-out and fees. Prices in Wales sit below our West Midlands baseline; sloping sites are the main variable.
| Size | Guide price inc VAT |
|---|---|
| L-shaped, about 22 m² of new floor | £45,000–£73,500 |
| L-shaped, about 30 m² of new floor | £61,500–£100,500 |
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 wraparound extension in Newtown?
Planning for a wraparound extension in Newtown follows the Welsh householder rules.
In Wales a single-storey side extension can be permitted development if it is no more than 4 metres high and the house ends up no more than 50% wider than the original. Many side return infills on terraced streets, and most wraparounds, go through a householder application.
The Party Wall etc. Act 1996 also applies in Wales: two months' notice for work to a shared wall and one month for foundations dug close to a neighbour's building.
Conservation areas, National Parks and National Landscapes restrict permitted development in Wales, and listed buildings need listed building consent. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.
What are homes in Newtown like to extend?
Older terraces near the centre and post-war semis further out are typical of Newtown. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

Do you handle building control in Newtown?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.

What postcode areas do you cover around Newtown?
Including SY16, and the surrounding Mid Wales area.
Do I need a party wall agreement?
In Wales, usually yes if the extension is on or near a shared boundary or close to a neighbour's foundations. We serve the notices.

Often not for a single-storey rear extension of up to 4 metres under Welsh permitted development. Wales has no prior approval route for deeper extensions.
