Do you need planning permission for a single-storey rear extension in Dungannon?
The planning route for a single-storey rear extension in Dungannon is set by Northern Ireland's householder rules and your council.
In Northern Ireland the Planning (General Permitted Development) Order (Northern Ireland) 2015 allows a single-storey rear extension of up to 3 metres on an attached house or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres within 2 metres of a boundary. Building control approval from the council is still required.
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. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Dungannon like to extend?
Semis and detached houses are typical of Dungannon, and many have room for a rear extension within Northern Ireland's permitted development limits.

FAQ
Single-storey rear extension questions in Dungannon
Is the site visit in Dungannon free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can I stay in the house during the build?
Usually yes. The noisiest, dustiest stage, removing the back wall, is kept to the final weeks and screened off. Most families set up a temporary kitchen elsewhere in the house.
What postcode areas do you cover around Dungannon?
Including BT71, and the surrounding County Tyrone area.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Can you match the brick or stone on my Dungannon house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
