Rear extensions for semi-detached houses in County Tyrone
Single or two-storey extensions for semi-detached houses, with side access and one party wall. We design and build rear extensions across County Tyrone, from Omagh and Strabane to Dungannon, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
Semi-detached houses are common across County Tyrone, and their side access makes rear extensions quicker to build. County Tyrone has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.

Do you need planning permission in County Tyrone?
Northern Ireland's permitted development rules allow a single-storey rear extension of 3 metres on terraced and semi-detached houses and 4 metres on detached houses, with a 4 metre height limit. Listed buildings, conservation areas and houses with removed rights need planning permission from the council.
Northern Ireland's 2015 Order allows a two-storey rear extension of up to 3 metres where at least 7 metres is left to the rear boundary. Anything larger, or in a conservation area, needs a planning application to the council.
Northern Ireland has no larger-extension prior approval route; anything beyond permitted development needs a planning application.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland.

FAQ
Questions people ask
Can I match pebbledash or render?
Yes. Many semis are refinished with new render across the whole back elevation so old and new match.
Single or two-storey on a semi?
Two-storey if you need bedrooms, single-storey if you need a bigger kitchen. Planning risk is lower for single-storey.
What if my neighbour has already extended?
That can make a matching depth easier to justify. We measure theirs at the survey.
Do you cover all of County Tyrone?
We cover 6 towns and districts in County Tyrone, including Omagh, Strabane and Dungannon.
