Rear extensions for terraced houses in County Armagh
Rear and side return extensions for terraces, with access through the house and two neighbours. Across County Armagh we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Craigavon, Portadown and Armagh.

Terraced streets make up much of the housing in parts of County Armagh, and most rear extensions here go in without side access. County Armagh 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 Armagh?
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 Armagh?
We cover 3 towns and districts in County Armagh, including Craigavon, Portadown and Armagh.
Who builds the extension?
Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
