Across BT42, BT43, we can visit, measure and advise. Neighbouring towns we cover include Antrim (10 miles), Larne (18 miles), Newtownabbey (20 miles), Carrickfergus (21 miles).
In Northern Ireland, extension projects follow the NI planning rules and council building control, which we account for from the first survey.

A lawful development certificate is not compulsory for permitted development, but it is the cleanest proof that the extension was lawful when you come to sell. We usually recommend one.
Do I need planning permission in Ballymena?
In Northern Ireland we check the permitted development limits for your house type and, where needed, apply to your council for planning permission, then submit full plans or a building notice to council building control.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Northern Ireland has no Party Wall Act. Where work is on or close to a shared boundary, we agree access and protection with your neighbour in writing before work starts.
Applications are decided by your council, which handles local planning in Northern Ireland.

Questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Ballymena, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Ballymena be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
How long does this take for a Ballymena home?
8–13 weeks typical decision period, depending on the council and the complexity of the project.
What happens if planning is refused?
You can revise the design and reapply, or appeal. We read the officer’s report and tell you honestly which option has a better chance.
