Kitchen-diner rear extension in Ballymena
We plan and build kitchen-diner rear extensions for homeowners in Ballymena. An open-plan kitchen, dining and family room that opens straight onto the garden. Start with a free site visit, then a written price once the design is agreed.
We cover Ballymena (BT42 and BT43) as part of our County Antrim work. A kitchen-diner is often the reason people in Ballymena extend: the back kitchen in semis and detached houses is rarely big enough for a table.

Do you need planning permission for a kitchen-diner rear extension in Ballymena?
Planning for a kitchen-diner rear extension in Ballymena follows the Northern Irish householder rules.
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 Ballymena like to extend?
Semis and detached houses are typical of Ballymena, and many have room for a rear extension within Northern Ireland's permitted development limits.

FAQ
Kitchen-diner rear extension questions in Ballymena
Is the site visit in Ballymena free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
How much does a kitchen-diner rear extension cost in Ballymena?
As a guide, £1,650–£2,700 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £20,000–£32,500 at that rate. Your written price follows the survey.
Should the sink face the garden?
If the plan allows, an island sink or hob facing the glass is a common choice. It needs a floor-level drain run, which is easy to lay in a new slab.
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 I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Can you match the brick or stone on my Ballymena house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
