The main conference was held inside an early railway maintenance building. Cast iron columns, cast iron presses. "Made in Leeds” Manchester, Birmingham. Outsized remnants fortuitously left in-place.
The previous evening, Sydney Town Hall hosted a public meeting with keynote speakers, Emilio Ambasz and Ken Yeang on stage. These green of centre architects revolutionise cityscapes with hanging gardens.
There was a bit of a ruckus in the bleachers, a drunk using the opportunity to harangue Emilio Ambasz. Emilio didn’t back down.

Large buildings are actually draped with gardens by these pioneering architects to modify runoff from rain and high temperatures from radiated heat. Cities in Germany and Switzerland, require landscaping to cover buildings as a condition of permission to build. Tokyo too uses green roofs and walls, in a desperate quest to stabilise an environment radiating heat from an epidemic of concrete.
All this and more, is doubtless coming to a city near you.
