The rare opportunity to work on an entire city block allowed them the scope to extend their contribution from architecture through to urban planning and design. Important in the creation of this urban jigsaw puzzle was to constantly bear in mind how these buildings would work together and how those working in the precinct would experience the environment. There are common threads that run throughout the precinct, but each building has a subtle change of evolutionary design. The design language used throughout the three phases ties the buildings together whilst the individuality of the buildings is expressed through the use of different materials.
