What do rear extension planning drawings cost in Bangor?
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. These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a rear extension in Bangor?
Planning for a rear extension in Bangor 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. 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 Bangor like to extend?
Semis and detached houses are typical of Bangor, and many have room for a rear extension within Northern Ireland's permitted development limits.
