One of the new building groups out at the hospital is the Koop Center (SBRA, 2008-2010). See the floorplan (pdf). A view of the interior of the volume joining the center’s two wings, called LeBaron Commons, is available as well (pdf). One of the wings has a name that seems to be fairly new: the Williamson Translational Research Building.

For reference, this big addition seems to be at the bottom of the current hospital map (pdf).

A perspective drawing of the complex suggests the direction of the Medical School’s “Future Campus” (pdf).
