Do you need planning permission for a two-storey rear extension in Dungannon?
Whether your two-storey rear extension in Dungannon needs a planning application depends on its size, your house and any local restrictions.
In Northern Ireland a rear extension of more than one storey can be permitted development if it projects no more than 3 metres and stays at least 7 metres from the rear boundary. Two-storey extensions in conservation areas, and most larger schemes, need planning permission from the council.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. 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 Dungannon like to extend?
