Wraparound extension in Rhyl
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 Rhyl and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Rhyl (LL18) as part of our North Wales work. Wraparound projects around Rhyl often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Rhyl?
Planning for a wraparound extension in Rhyl follows the Welsh householder rules.
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 Rhyl like to extend?
Older terraces near the centre and post-war semis further out are typical of Rhyl. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.

FAQ
Wraparound extension questions in Rhyl
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.
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.
Will it take a lot of garden?
Less than a deep rear extension of the same area, because part of the space comes from the side passage.
Do you handle building control in Rhyl?
Yes. We apply to the council or a registered approver under the Welsh regulations and hand over the completion certificate.
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.
Do I need planning permission for a rear extension in Rhyl?
Often not for a single-storey rear extension of up to 4 metres under Welsh permitted development. Wales has no prior approval route for deeper extensions.
