Do you need planning permission for a two-storey rear extension in Limavady?
Planning for a two-storey rear extension in Limavady follows the Northern Irish householder rules.
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 Limavady like to extend?
Semis and detached houses are typical of Limavady, and many have room for a rear extension within Northern Ireland's permitted development limits.

Often not for a single-storey rear extension of up to 3 metres (4 metres detached) under Northern Ireland's permitted development rules, outside conservation areas.

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
