Do you need planning permission for a glazed rear extension in Llandudno?
Whether your glazed rear extension in Llandudno needs a planning application depends on its size, your house and any local restrictions.
The Welsh Government's householder rules let many homes add a single-storey rear extension up to 4 metres deep and 4 metres high without a planning application. Deeper projects go through a householder application, because Wales has no prior approval route.
Wales has its own Approved Document L, with targets for walls, roofs, floors and glazing similar to but not identical with England's. Heavily glazed designs are checked with a calculation.
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 Llandudno like to extend?
Older terraces near the centre and post-war semis further out are typical of Llandudno. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
