I don't know if there's a thread for this already but it's an excuse to share this
ARTE program (in French, but subtitles are always possible) which features people like Kengo Kuma. And maybe there are similar things out there which come to mind, whatever they advocate.
As a Canadian in France, I'm particularly interested in projects, trends, initiatives, etc., which could directly or indirectly be relevant in / to Canada. In this show, for example, Kuma talks about how he wants to help create smaller-scale, lower buildings / neighbourhoods in Tokyo, which of course goes against the height preference of many.
