Rear extensions for terraced houses in County Tyrone
Rear and side return extensions for terraces, with access through the house and two neighbours. Rear extensions in County Tyrone: we cover 6 towns including Omagh, Strabane and Dungannon, with design, approvals and the build under one contract.

In Omagh we plan the delivery route through the house and the skip licence before anything else. Semis and detached houses are typical of County Tyrone, and many have room for a rear extension within Northern Ireland's permitted development limits.

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.
There is no Party Wall Act in Northern Ireland; we agree any work affecting a shared wall or boundary directly with the neighbour, in writing.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland.

FAQ
Questions people ask
Can you build without side access?
Yes. Materials come through the house in protected runs or over the roof by crane on tight sites.
Will my terrace be in a conservation area?
Many Victorian terraces are. Your council's map shows it; we check at the survey.
Can a terrace have a two-storey rear extension?
It is possible but harder to get through planning because of the effect on both neighbours.
Do you cover all of County Tyrone?
We cover 6 towns and districts in County Tyrone, including Omagh, Strabane and Dungannon.
Who builds the extension?
Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
