Frequently asked questions

When do you need planning permission for a house extension?
Single-storey rear extensions up to 4m (detached) or 3m (semi-detached / terraced) are usually permitted development. Two-storey extensions, anything in a conservation area, or larger projects almost always need a planning application.
What's the difference between planning permission and permitted development?
Permitted development rights let you build certain things without applying for planning permission, subject to specified limits. Anything outside those limits, whether taller, larger or in a protected area, needs full planning permission.
How long does a householder application take?
The statutory target is 8 weeks from validation. Most simple householder extensions are decided within that window; complex or contested cases, especially those drawing a lot of comments, can take longer.
Can I get email alerts for new extensions applications in Causeway and Glens?
Yes. Click "Set up alerts" on this page and you'll get a daily or weekly email listing every new extensions application published by Causeway and Glens. You can also narrow the alert to a postcode, street, or drawn area.

We check Causeway and Glens's planning portal daily. New extensions applications appear here within a day of being published.
