Homes in County Tyrone
Northern Ireland has a high proportion of detached houses and bungalows outside the cities, which often suit side extensions, rear extensions and upward extensions.
What is included in a double-storey extension in Cookstown?
Two-storey work has to sit comfortably with the house and the neighbours, so most of the design effort goes into the roofline, window positions and how the new first floor connects to the landing. We handle the planning application, the structural design and the building control process, then build, roof and finish both floors.
- Householder planning application
- Structural engineer’s design and calculations
- Windows, insulation, plastering, electrics and plumbing
