Back in 2005, my partner and I decided to build a green roof on the rear extension to our house, partly to improve insulation, partly to provide a mini-wilderness environment for local plants, insects and birds to use, and partly to see what would actually survive in such a harsh environment. We calculated that with a 25% safety margin, the maximum weight of soil and rain or snow would come to about 2 tons, so some major strengthening of the roof took place, following which we built a 6 inch deep paddling pool, lined with carpet and a butyl pond liner. The soil was all sourced locally from friends and neighbours, and it has been left un-watered and un-weeded for the last 3 years.
