The covered Street provides for a weather-friendly link between each of the buildings and the drop-off point at the Southern end of the site. The central Street has an overhead roof of curved glass vaults supported on slender steel columns, 3 stories high. The structure both unites the separate buildings into one readily identifiable development and also provides a clearly defined circulation route across the site. 

Each building plan is arranged about a central or peripheral Atrium ensuring availability of natural daylight to all areas and approx. 50,000 m2 gross internal floor space is provided.
