Wraparound extension in Newport
For homes in Newport, a wraparound extension is often the simplest way to gain space without moving. An L-shaped extension that fills the side return and runs across the back. We take it from survey to completion certificate.
Newport is covered from our Newport and Monmouthshire round, including NP10, NP18, NP19 and NP20. Wraparound projects around Newport often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Newport?
Planning for a wraparound extension in Newport follows the Welsh householder rules.
Welsh side-extension rules limit a single-storey side addition to 4 metres high and a 50% increase in the width of the original house, with tighter limits in conservation areas. Wraparounds usually need a planning application.
In Wales, as in England, the Party Wall etc. Act 1996 requires notice to neighbours before work to a shared wall or excavation near their foundations.
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 Newport like to extend?
Older terraces near the centre and post-war semis further out are typical of Newport. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Wraparound extension questions in Newport
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 you match the brick or stone on my Newport house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Is the site visit in Newport free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can I get a price without a visit?
