Do you need planning permission for a two-storey rear extension in Armagh?
The planning route for a two-storey rear extension in Armagh is set by Northern Ireland's householder rules and your council.
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 Armagh like to extend?
Armagh has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.

FAQ
Two-storey rear extension questions in Armagh
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
What postcode areas do you cover around Armagh?
Including BT61, and the surrounding County Armagh area.
Do I need planning permission for a rear extension in Armagh?
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.
Can you match the brick or stone on my Armagh house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
