The design infills an underutilised courtyard over three levels, creating additional accommodation and opening up the plan to natural light and views of surrounding greenery. A dramatic central spheroid light well, large glazed sawtooth roof ridges, and voluptuous ceiling valleys break up the rigidity of the interior and draw light deep into the floorplan and lower levels. New contemporary cross-team collaborative and short-term individual spaces create work neighbourhoods that are a clear shift from the former individual office model.
