What do rear extension planning drawings cost in Coleraine?
As a guide, £1,000–£2,500 including VAT for a single-storey rear extension, or £2,000–£3,500 for a two-storey scheme. Planning fees in Northern Ireland are set by the Department for Infrastructure; we confirm the current householder fee when we submit. Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a rear extension in Coleraine?
Planning for a rear extension in Coleraine 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.
Northern Ireland councils work to a 15-week target for local applications, which include householder extensions; many householder decisions come sooner.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Coleraine like to extend?
Semis and detached houses are typical of Coleraine, and many have room for a rear extension within Northern Ireland's permitted development limits.
