Kitchen-diner rear extension in Larne
An open-plan kitchen, dining and family room that opens straight onto the garden. We design, get the approvals for and build kitchen-diner rear extensions in Larne and the surrounding area, with one contract from the first survey to building control sign-off.
Larne sits in County Antrim, with postcode districts including BT40. For Larne kitchens we plan the extraction route and the island drainage before the slab is poured, so nothing has to be chased in later.

Do you need planning permission for a kitchen-diner rear extension in Larne?
Here is how the rules in Northern Ireland apply to a kitchen-diner 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?
Larne has terraces near the centre, semis on the edges and many detached houses and bungalows in the surrounding countryside, where plots are often generous.
