Area of Significant Archaeological Interest
Protected historic landscape around monuments
An Area of Significant Archaeological Interest is a distinctive historic landscape holding a group of related sites and monuments. The designation exists only in Northern Ireland. A district council designates it in its local development plan, advised by the Department for Communities Historic Environment Division. It carries development plan policy rather than a separate consent regime.
What This Means
Owning and occupying this property is not restricted. You can repair, redecorate and maintain the home with no extra heritage step. The designation weighs when you apply for planning permission. The council must consider the effect of your proposal on the character of the landscape. It also weighs the setting of the monuments in it. That can shape the siting, height and materials of an extension or outbuilding, not only any digging. This does not normally affect mortgage approval, buildings insurance or resale.
Practical Advice
- Ask your solicitor to obtain the district council's property certificate and check it for archaeological conditions on earlier permissions.
- Ask the district council's planning team for pre-application advice on how your proposed extension would affect the area's character and setting.
- Commission a heritage impact assessment from an archaeological consultant before you finalise the design of any extension or outbuilding.
Key Points
- The eleven designated areas include the Giant's Ring, Navan, Beaghmore, Downpatrick, Dunluce and the Dorsey.
- A like-for-like rear extension is approved; a taller two-storey extension on the same plot is refused for its effect on views to the monument.
Additional Information
Great Britain has no Area of Significant Archaeological Interest. England's nearest equivalents are local plan archaeology zones and five statutory Areas of Archaeological Importance. Wales protects its archaeology under the Historic Environment (Wales) Act 2023. The exact boundary on this plot can be viewed on the Department for Communities historic environment map viewer.
