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