Green Roofs are Changing Architecture and Planning

Metro Convention Centre, Toronto

Nobody even called them green roofs, they were just landscaped decks, like this one over the buried portion of the Metro Convention Centre in Toronto, a political expediency where they wanted to expand but the land was designated for a park, so they put it underground and landscaped the top of it. This was before the term "green roof" was in common use, or they would have made a virtue of it, instead of a necessity. It makes a lousy park and a worse convention centre, but you have not seen the last of this idea.
