Do you need planning permission for a wraparound extension in Aberdare?
Whether your wraparound extension in Aberdare 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. 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 Aberdare like to extend?
Stone terraces along the valley floors and post-war semis higher up are typical of Aberdare. Sloping sites are common, so floor levels and retaining walls are designed at the start.
