The 5 level podium is predominantly precast concrete. This was chosen as it is consistent with a number of the surrounding buildings which have a solid expression predominantly in concrete. The podium takes the form of angled widow boxes. These boxes are angled to maximise sun penetration and create a stark modelling in sunlight. This articulation creates a lively contemporary expression which reflects its surroundings.

The majority of the façade is clad in adjustable metal louvre screens in a copper tone. These screens provide shading to reduce heat load as well as screen balconies for privacy and aesthetic appearance. The screens are unique in that they sometimes span 2 levels. This is achieved using an ingenious track system to avoid clashes. The mixture of screens of different heights creates a unique mosaic patterning. The building contains a 6m x 6m ventilation shaft. This shaft provides natural ventilation to the units.
