Wraparound extension in Caldicot
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 Caldicot and the surrounding area, with one contract from the first survey to building control sign-off.
Caldicot is covered from our Newport and Monmouthshire round, including NP26. Wraparounds are the natural next step for the end-of-terrace and Victorian houses in Newport and Monmouthshire where a side return alone would leave the room too narrow.

Do you need planning permission for a wraparound extension in Caldicot?
Whether your wraparound extension in Caldicot needs a planning application depends on its size, your house and any local restrictions.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Caldicot like to extend?
Caldicot has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.

FAQ
Wraparound extension questions in Caldicot
Do you handle building control in Caldicot?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
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.
What roof suits a wraparound?
A flat roof with a lantern, a standing-seam pitched roof or a glazed roof over the side leg. The choice usually follows the first-floor windows above.
Can you match the brick or stone on my Caldicot 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 rear extension take to build in Caldicot?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
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.
