Homes in County Antrim
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 is an upward extension?
An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.
- New first-floor structure, walls and roof
- Staircase and changes to the ground floor layout
- Full fit-out of the new rooms

Adding a storey in Northern Ireland needs planning permission and building control approval.

How does the project run?
