This is the final phase of Radiation Therapy.

In this phase everything came together. I established and fully developed all of the zones, and everything leads back to a unifying factor- the tree.  The private zone is demarcated by a pure circle, and it is comprised of research labs, administrative space, circulation, and open pavilion space.  The landscape outside of this pure circle is inspired by tectonic forms and the effects of subduction.  The transition zone is demarcated by the radiation sensors.  The public zone is identifiable by the gridded trees.  Within this grid, there are also satellite trees, which allow for communication inside and outside, and outposts, which facilitate research outside the labs.  The public zone transcends the private zone by way of the scars on the landscape.  These scars lead directly to the tree, which makes the public contemplate the existence of the site, the way they view nature, and how they live.
