There is an interesting article from designboom.com that reflects on the notion of natural architecture, a movement that seeks to reconnect architecture with nature. The article speaks to the work of Alessandro Rocca, who published 'Natural Architecture' in 2006. The concept behind natural architecture expands on the land art movement and ultimately seeks to merge humanity and the environment. It challenges the standard concept of architecture, to create shelter from nature and instead seeks to embrace nature in shelter.
It seems to me that natural architecture is simply a synonym for landscape architecture. In fact, I would challenge this "architectural" movement and insist that as landscape architects, we strive to design within the constructs of natural systems and bring people closer to the idea of nature.
