Do you need planning permission for a two-storey rear extension in Strabane?
Planning for a two-storey rear extension in Strabane follows the Northern Irish householder rules.
Northern Ireland's 2015 Order allows a two-storey rear extension of up to 3 metres where at least 7 metres is left to the rear boundary. Anything larger, or in a conservation area, needs a planning application to the council.
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 Strabane like to extend?
Strabane 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 Strabane
Do I need planning permission for a rear extension in Strabane?
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 Strabane house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
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.
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 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.
