Planning: Lisburn and Castlereagh City Council

In Northern Ireland the householder rules follow the same pattern as England: a low deck behind the house that keeps within the garden-coverage limit is permitted development, while a raised platform, a deck in front of the house, or one at a flat or listed building needs an application to the council, which is the planning authority.
