I was just at the Biennale di Architettura in Venice, and the subject of nature and architecture--in my opinion--was sorely lacking. I posted my thoughts about it here, if you are interested. I think adding green space is important, but we know enough about the importance of a connection to nature (biophilia) to go a step further, I think. And if this is the cutting-edge of architecture, I expected more conversations of how "freespace" connects to the freedom we feel in nature, don't you think?
