County Armagh
Rear extension plans and planning applications in County Armagh
Measured survey, design options, planning drawings and the application, handled for you. We design and build rear extensions across County Armagh, from Craigavon and Portadown to Armagh, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.

Planning applications in Craigavon go to the local planning authority, and we check its local design guidance for rear extensions before drawing. Semis and detached houses are typical of County Armagh, and many have room for a rear extension within Northern Ireland's permitted development limits.
What does it cost in County Armagh?
As a guide, £1,000–£2,500 including VAT. Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
Do you need planning permission in County Armagh?
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.
Conservation areas, Areas of Outstanding Natural Beauty and listed buildings restrict permitted development in Northern Ireland.
Planning fees in Northern Ireland are set by the Department for Infrastructure; we confirm the current householder fee when we submit.
Northern Ireland councils work to a 15-week target for local applications, which include householder extensions; many householder decisions come sooner.
