Do you need planning permission for a terraced house rear extension in Bangor?
Planning for a terraced house rear extension in Bangor follows the Northern Irish householder rules.
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.
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 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.

FAQ
Terraced house rear extension questions in Bangor
Do I need a party wall agreement?
Northern Ireland has no Party Wall Act; we agree any shared-wall work with your neighbour in writing.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can you build without side access?
Yes. Materials come through the house in protected runs or over the roof by crane on tight sites.
Is the site visit in Bangor free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How long does a rear extension take to build in Bangor?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can you match the brick or stone on my Bangor house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
