- 3D views to check the look and the light (full pack)
- Two or three layout options to compare
- Structural calculations from an engineer (full pack)

The most expensive changes are the ones made after the steel is ordered. A good design stage settles layout, heights, glazing and services on paper, so the build price is firm.
Planning rules that apply in Magherafelt
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.
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.
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.

Design and approvals

Build and sign-off
