Wraparound extension in Mold

For homes in Mold, 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.

Mold and its postcode districts CH7 are part of our North Wales coverage. Wraparound projects around Mold often involve two neighbours, so we start the party wall conversations early.

Do you need planning permission for a wraparound extension in Mold?

Here is how the rules in Wales apply to a wraparound extension in Mold.

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. At the first visit we measure what is there now and tell you which route fits: permitted development or a householder planning application.

What are homes in Mold like to extend?

Mold has Victorian terraces near the centre and semis further out. Welsh permitted development allows up to 4 metres at the rear for many houses.
