| L-shaped, about 30 m² of new floor | £61,500–£100,500 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a wraparound extension in Clydach?
Planning for a wraparound extension in Clydach 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 Clydach like to extend?
Older terraces near the centre and post-war semis further out are typical of Clydach. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ

How long does a rear extension take to build in Clydach?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.

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.
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 Clydach free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
