Building rules in Derry City and Strabane
Building control in Derry City and Strabane is run by Derry City and Strabane District Council. Beams and new openings are controlled work under the Northern Ireland regulations, so we apply before anything is removed and the steel is inspected before it is covered.
The Party Wall etc. Act does not extend to Northern Ireland. Shared walls are dealt with under your title and the general law, so we recommend agreeing access and the work with your neighbour before it starts.

Steel beams in Derry City and Strabane: questions
Do I need a party wall agreement for steel beam installation in Derry City and Strabane?
There is no Party Wall Act in Northern Ireland. Your title deeds and the general law apply instead, so agree the work with your neighbour in writing before it starts.
Which towns in Derry City and Strabane do you cover?
We cover towns including Derry/Londonderry and Strabane, plus the villages and smaller towns around them.
Can I stay at home while the work is done in Derry City and Strabane?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
How soon can steel beam installation start in Derry City and Strabane?
Start dates depend on the engineer's calculations, the building control approval and any agreement needed with neighbours. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
What happens at the survey visit in Derry City and Strabane?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
