4A.11 Living roofs and walls
The Mayor will and boroughs should expect major developments to incorporate living roofs and walls where feasible and reflect this principle in DPD policies. It is expected that this will include roof and wall planting that delivers as many of these objectives as possible:
- Accessible roof space
- Adapting to and mitigating climate change
- Sustainable urban drainage
- Enhancing biodiversity
- Improved appearance.
Boroughs should also encourage the use of living roofs in smaller developments and extensions where the opportunity arises.
