When John and Shelley found an old trailer for sale, the idea was born; a green roof on wheels. But how to go about it? What system to use? What planting design? Lucky John, our green roof systems expert was up for the challenge.
When John picked it up, it was clear the trailer was in no shape to shine and a makeover was sorely needed before any construction could get done. Over the next few weeks John sanded and painted the trailer…and painted it again.
Next came the branding. We wanted to show case our partnership with the People’s Solar, and more than that, the partnership between green roofs and solar panels themselves.
Finally, the rover was ready to be planted.
With its even dimensions of 2.1m x 1.5m, the trailer roof was the perfect size for 12 modules, albeit with a bit of modification. Now, Do it on the Roof are big on waste management, so we were quick to give recycled materials a go. With the help of some practical friends, Jordie and Tony, we cut down some aluminium fly wire doors we had bought at the tip and fixed them to the frame to create a structural base.
After a road trip to Kuranga Nursery, the day of planting had come. Our ecologist, Trevor Edwards, had carefully selected a range of flowering native grasses and ground covers, along with some marshy plants (which would favour the lower slope of the modules). Now to create the perfect planting design.
We wanted to show case the beauty and variety of the plants, from the taller grasses to the flowering covers. Trevor suggested we construct a deeper planting bed in the centre of the trailer so as to plant an even greater diversity of plants. This great idea engendered a late night construction effort by John – thanks Trevor!
At last, armed with gloves and hats, plants lined up and our scoria-based substrate mix ready to shovel, we prepared to do battle.
Now sporting its flowering native roof and equipped with the solar panel, the sustainability rover was ready to roll. A victory for the whole team (and above all for John).
