London's largest living wall

This is a fantastic project by Gary Grant of Green Roof Consultancy.

To promote sustainable drainage systems and combat flooding, this hotel has installed 10,000 plants recommended to attract wildlife such as bees, butterflies and birds to the urban environment and it has been designed in an attempt to reduce local environmental issues such as surface flooding and air pollution. It will be irrigated by harvested rainwater caught on the roof.
