Green roofs for biodiversity - the idea stems from seminal work on the subject by Dr. Stepahn Brenneisen in Switzerland. This video shows the trasformation of s green roof designed for biodiversity over a 5 year period, from installation in 2005 until the summer of 2010.

This green roof sits on a anew development that has undergone a refurbishment. The main roof was installed by Oikesteges , the only 'indigenous' Greek Green Roof Company. The lower roof is a different system, one that was provided by Zinco, who partner in the UK with Alumasc-Exteriors.
