The central spine becomes an organizing element along the seam between the two converging plan geometries. The spine unifies the site and becomes a collector and main pedestrian movement corridor through the heart of the site, and as such, several layers of elements are represented along the spine. The paving along the spine follows a 750mm x 750mm grid. The module creates a system for varying the design elements. The spine creates a strong sense of place and unique character through a monumental form that is repeated through pedestrian-scales spaces, and unifies the spaces of both the at-grade portions of the site, as well as the sunken garden. The trellis features knit together a series of urban spaces that are civic, public and individual.
