Wraparound extension in Risca
We plan and build wraparound extensions for homeowners in Risca. An L-shaped extension that fills the side return and runs across the back. Start with a free site visit, then a written price once the design is agreed.
Risca and its postcode districts NP11 are part of our South Wales Valleys coverage. In Risca we usually draw the wraparound and a simpler rear-only option side by side, so the planning risk and cost difference are clear.

Do you need planning permission for a wraparound extension in Risca?
Planning for a wraparound extension in Risca 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. 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 Risca like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Risca. Sloping sites are common, so floor levels and retaining walls are designed at the start.
