House extensions in Caernarfon
Many extensions in Caernarfon are single-storey kitchen-diners on the back of semis and terraces, where the original kitchen is small and the garden is the only way to get more room.
Outside the historic centre, a single-storey rear extension can often be built under Welsh permitted development rules – up to 4 metres past the back wall and up to 4 metres high. Inside the Caernarfon Conservation Area, two-storey extensions always need a planning application.
