What is a wraparound extension?
A wraparound extension combines a side return and a rear extension into one L-shaped addition. It gives the largest possible ground floor, often creating an open-plan kitchen, dining and living space across the whole width of the house.
How much does a wraparound extension cost in Strabane?

Do you need planning permission for a wraparound extension in Strabane?
Before anything is built in Strabane, we confirm which approvals apply in Northern Ireland. In Northern Ireland a wraparound extension normally needs planning permission and building control approval.
