Whitchurch, Cardiff and the Vale
Wraparound extension in Whitchurch
For homes in Whitchurch, 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.
We cover Whitchurch (CF5, CF14 and CF15) as part of our Cardiff and the Vale work. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Cardiff and the Vale where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Whitchurch?
Whether your wraparound extension in Whitchurch needs a planning application depends on its size, your house and any local restrictions.
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 Whitchurch like to extend?
Older terraces near the centre and post-war semis further out are typical of Whitchurch. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Wraparound extension questions in Whitchurch
Can you match the brick or stone on my Whitchurch house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
How long does a wraparound take?
Usually 14 to 20 weeks on site, longer than a plain rear extension because of the steelwork.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
How long does a rear extension take to build in Whitchurch?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
