Redfern Green roof
This project in Redfern, Sydney is on the 6th floor. It provided a unique challenge due to exposure and depth of soil requirements.
The project has now been installed for over a year and both plants and client are very happy.
For installation we only has 120mm depth to play with. This included waterproofing, drainage layer, growing media and mulch. All products had to be brought up by lift and moved through a residence. The roof was first checked for leaks, and a leak detection system was installed. Growing media was designed by Robert Griffith based on his international experience with green roofs . Plant species were selected for their hardiness and display, this was a decorative garden for use by the clients, all windows in the house look over the garden. Apart from the extensive (light weight) green roof a number of large pots and a green wall around the spa was installed. Automatic irrigation was installed for all plantings.
