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

FAQ
Kitchen-diner rear extension questions in Holywood
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.
How much does a kitchen-diner rear extension cost in Holywood?
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.

Often. A narrow utility or boot room along one side keeps the washing machine out of the open-plan space.

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
