In Northern Ireland, extension projects follow the NI planning rules and council building control, which we account for from the first survey.
Planning rules that apply in Carrickfergus
In Northern Ireland the Planning (General Permitted Development) Order 2015 lets some single-storey rear extensions go ahead without planning permission, up to 3 m on a semi-detached or terraced house and 4 m on a detached house, within height and boundary limits. Larger, side and two-storey extensions normally need planning permission from the council, and building control approval is separate.
Homes in conservation areas, areas of townscape character and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
In Northern Ireland building control is run by the councils under the Building Regulations (Northern Ireland). We submit full plans or a building notice and book the inspections through to completion.
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.

Your questions about a kitchen extension in Carrickfergus
Will my neighbours in Carrickfergus 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 a kitchen extension take to build in Carrickfergus?
On site, typically 10 to 16 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Do I need building regulations approval in Carrickfergus?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can you fit a kitchen I buy elsewhere?
Yes. We can fit it or work with your supplier’s fitters. We need the layout early so that drains, services and lighting are in the right place.
How much does a kitchen extension cost?
For the extension itself our guide range is about £1,550 to £3,010 per m² including VAT. A standard 20 m² kitchen extension is typically around £36,000 to £46,000 in Carrickfergus, plus the kitchen itself, which commonly adds £9,000 to £20,000 for a mid-range design.
