Do you need planning permission for a glazed rear extension in Coalisland?
The planning route for a glazed rear extension in Coalisland is set by Northern Ireland's householder rules and your council.
Northern Ireland's permitted development rules allow a single-storey rear extension of 3 metres on terraced and semi-detached houses and 4 metres on detached houses, with a 4 metre height limit. Listed buildings, conservation areas and houses with removed rights need planning permission from the council.
Insulation and glazing follow Technical Booklet F1 in Northern Ireland, checked by council building control.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application.
