Do I need planning permission in Newtownabbey?
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.
The planning position for a specific Newtownabbey address depends on its history and any designations, which is why we check it at the first visit.
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.
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.
Applications are decided by your council, which handles local planning in Northern Ireland.
Included in a typical project
- Trial holes to check the existing foundations
- Removal and disposal of the old conservatory
- New or upgraded foundations
- Insulated walls and roof to current regulations
- Opening widened into the house if wanted
- Glazing and doors to suit the new room
A replacement is a chance to rethink the shape. Many conservatories are oddly proportioned; for a similar cost the new room can often be squarer, wider or better connected to the kitchen.

Common questions in Newtownabbey
Do I need building regulations approval in Newtownabbey?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Newtownabbey, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Newtownabbey?
Yes. We cover Newtownabbey and the surrounding parts of County Antrim. Site visits are free and there is no obligation.
Can I keep the existing base?
Sometimes, but conservatory bases are often too shallow for solid walls. Trial holes tell us before we confirm the price.
Is it worth replacing a conservatory with an extension?
If the conservatory is unusable for much of the year, usually yes. A solid extension gives a heated room that counts as proper living space. Our guide range is about £1,590 to £3,010 per m² including VAT, including removal.
