What a building regulations application involves
This service suits every two-storey extension, because each one needs building regulations approval wherever you live in the UK. You get technical drawings and a specification coordinated with the structural engineer, a full plans application, site inspections arranged at each stage, and the completion certificate you will need when you sell. We manage the process, and the work is carried out by vetted teams working under S&K.
The main places we list in County Tyrone are Omagh (BT78), Strabane (BT82), Dungannon (BT69), Cookstown (BT80), Coalisland (BT71) and Dromore (County Tyrone) (BT78). We cover the villages in between too.
Fees
Technical drawings and specification are a guide of £1,500–£4,000. The council's building control fee depends on the value of the work; we confirm every fee in writing before the design stage starts.
Rules in Northern Ireland
In Northern Ireland, building control approval comes from the local council under the Building Regulations (Northern Ireland), with the Technical Booklets setting out how to comply. A full plans application is usual for two-storey extensions, and the council inspects the work and issues a completion certificate.
Approval in Northern Ireland: Planning application for works to a house: £347. Councils aim to decide local applications within an average of 15 weeks; many take longer.
Building control: Building control approval from the local council under the Building Regulations (Northern Ireland), using the Technical Booklets.
There is no Party Wall Act in Northern Ireland. Shared walls and boundaries are a matter of title and common law, so we agree access and record conditions with neighbours before work starts.
Getting the design right
Full plans and inspections
Full plans approval checks the design before work starts, which we recommend for two-storey extensions. Building control then inspects key stages, such as foundations, damp-proofing, drainage and insulation, before issuing the completion certificate.

Building regulations for two-storey extensions in County Tyrone: questions
What is a build-over agreement?
A build-over agreement is permission from your water company to build over or near a public sewer. Many rear extensions sit near shared drains, and the water company will want access protected and the pipe checked. We check sewer records early so the agreement does not delay the start.
Do I need building regulations if I have planning permission?
Yes. Planning permission and building regulations are separate. Planning covers what the extension looks like and how it affects neighbours; building regulations cover how it is built and whether it is safe, warm and healthy. A two-storey extension needs both, unless permitted development replaces the planning part.
