Homes in County Down

Housing in Northern Ireland mixes terraces in Belfast and Derry with detached houses and bungalows in towns and rural areas, many with room to extend.

What goes into a wraparound extension?

A wraparound extension combines a side return and a rear extension into one L-shaped build, giving the biggest possible ground-floor space on terraced and semi-detached houses. It usually creates a large open-plan kitchen, dining and living area across the back of the house.

Planning and building rules in County Down
