Planning rules that apply in County Tyrone

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.

Applications are decided by your council, which handles local planning in Northern Ireland.

What happens next

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

  1. Free site visit

    A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.

  2. Design and approvals

    Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.

  3. Fixed written price

    With the design and specification agreed, you get a fixed written price and a start date.

  4. Build and sign-off

    Work is carried out to the agreed programme, inspected by building control and signed off at the end.

Common questions in County Tyrone

Do you cover all of County Tyrone?

Yes, across the whole of County Tyrone. Site visits are free and there is no obligation.

How long does a home office extension take to build in County Tyrone?

On site, typically 8 to 12 weeks once approvals are in place. Before that, allow 4–10 weeks design and approvals.

Can I see a price before committing to anything?

Yes. The guide prices on this page are adjusted for County Tyrone, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

Can I claim the cost against tax?

Building work on your home is not normally an allowable business expense, and claiming it can have capital gains tax effects. Speak to an accountant before assuming any tax relief.

Is an attached office better than a garden office?

An attached office shares the house heating and broadband, adds floor area to the home, and needs no garden path in the rain. A garden building can be cheaper and quicker but is a separate structure.
