Do I need planning permission in Magherafelt?
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.
The planning position for a specific Magherafelt 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.
Building close to a public sewer needs the agreement of NI Water, which we check during design.
Applications are decided by your council, which handles local planning in Northern Ireland.
What we take care of
- Structural calculations for beams, lintels and foundations
- Completion certificate on sign-off
- Inspection bookings throughout the build
- Building regulations drawings and written specification
- Energy and glazing checks, including whole-house calculations if needed
Building regulations approval and planning permission are separate. A design can have planning consent and still need changes to meet the regulations, which is why we draw for both together.

Questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Magherafelt, 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 Magherafelt 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.
Do I need building regulations approval in Magherafelt?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Full plans or building notice?
A full plans application gets the drawings checked before work starts, which we usually recommend for extensions. A building notice is quicker to submit but carries more risk if something needs changing on site.
