Side return extensions in County Armagh
Infilling the narrow passage beside a Victorian or Edwardian back addition. 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.

Side returns suit the Victorian and Edwardian terraces found across parts of County Armagh, where the kitchen sits in a narrow back addition. 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 rules restrict side extensions more than rear ones, so a side infill or wraparound usually needs a planning application to the council as well as building control approval.
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
How much space does a side return add?
Typically 8 to 18 square metres, enough to turn a galley kitchen into a kitchen-diner with an island.
Can I combine a side return with a rear extension?
Yes; that is a wraparound extension, and it gives the biggest open-plan room a terrace can have.
Glass roof or solid roof with rooflights?
A glass roof gives the most light; a solid roof with long rooflights is warmer and quieter in rain. Both work.
Do you cover all of County Armagh?
We cover 3 towns and districts in County Armagh, including Craigavon, Portadown and Armagh.
