Do you need planning permission for a glazed rear extension in Abergele?
Planning for a glazed rear extension in Abergele follows the Welsh householder rules.
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. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Abergele like to extend?
Older terraces near the centre and post-war semis further out are typical of Abergele. Sloping sites are common in Wales, so floor levels and retaining walls are designed at the start.
