Do you need planning permission for a two-storey rear extension in Caldicot?
Whether your two-storey rear extension in Caldicot needs a planning application depends on its size, your house and any local restrictions.
In Wales a rear extension of more than one storey can be permitted development if the ground floor projects no more than 4 metres and the upper floor no more than 3 metres, with at least 10.5 metres to the rear boundary. It is not permitted development in conservation areas, National Parks or National Landscapes, so many double-storey schemes need a householder application.
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 Caldicot like to extend?
Older terraces near the centre and post-war semis further out are typical of Caldicot. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
