Do you need planning permission for a bungalow rear extension in Larne?
Here is how the rules in Northern Ireland apply to a bungalow rear extension in Larne.
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.
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. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application.
What are homes in Larne like to extend?
Semis and detached houses are typical of Larne, and many have room for a rear extension within Northern Ireland's permitted development limits.

FAQ
Bungalow rear extension questions in Larne
Do I need a party wall agreement?
Northern Ireland has no Party Wall Act; we agree any shared-wall work with your neighbour in writing.
What postcode areas do you cover around Larne?
Including BT40, and the surrounding County Antrim area.
Can I extend the loft as well?
Sometimes, but that is a different project; a rear extension keeps everything on one level.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
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 you match the brick or stone on my Larne house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
