Across Northern Ireland you find city terraces, suburban semis and rural bungalows and farmhouses, so the right approach depends on the plot and the planning history.

What is included in a double-storey extension in Newtownards?

A double-storey extension adds new rooms on both the ground and first floor in one build, typically a larger kitchen or living space downstairs and an extra bedroom or bathroom above. Because the roof and foundations are shared, the cost per square metre is usually lower than a single-storey extension.

What approvals does a double-storey extension need in Northern Ireland?

Northern Ireland projects need planning clearance and building control approval from the local council. We prepare the applications and agree any work near neighbouring property directly with the neighbours.

Two-storey extensions in Northern Ireland normally need planning permission from the council, plus building control approval.

What should Newtownards homeowners check first?

Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
The new roof is tied into the old one, so roof tiles and ridge details need to match.

Your questions answered

How long does a two-storey extension take?

Around 14 to 24 weeks on site, plus the planning period before that.
