What is included in a wraparound extension in Monmouth?
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.
- Design, planning drawings and structural calculations
- Party wall process with both neighbours if needed
- Pitched, flat or glazed roof with rooflights
