What is a wraparound extension?
Because it removes two external walls, a wraparound needs careful structural design and a good plan for the corner where the steels meet. We design, apply for any permissions, build and finish the shell, and can fit the kitchen as part of the same contract.
- Pitched, flat or glazed roof with rooflights
- Glazing, insulation, plastering and electrics
