Do you need planning permission for a side return extension in Magherafelt?
Whether your side return extension in Magherafelt needs a planning application depends on its size, your house and any local restrictions.
Northern Ireland's rules restrict side extensions more than rear ones, so a side infill or wraparound usually needs a planning application to the council as well as building control approval.
There is no Party Wall Act in Northern Ireland; we agree any work affecting a shared wall or boundary directly with the neighbour, in writing.
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 Magherafelt like to extend?
Semis and detached houses are typical of Magherafelt, and many have room for a rear extension within Northern Ireland's permitted development limits.
