The building consists of three storeys with a basement for storage.  The building structure is of a reinforced concrete frame up to second floor level with a steel framed roof construction.

The first floor cantilevers beyond the ground floor by up to 4 metres in places.  An arrangement of deep beams around the perimeter of the building, supported by orthogonal deep beams located strategically internally, are used to deal with the large and extensive cantilevers.  The second floor slab is also designed as a transfer structure to support the roof columns which do not align in many instances with the structure
below.  Stability is achieved through the concrete cores and shear walls.

The building is piled to deal with the high column loads and also to deal with the numerous trees on the site that have caused substantial problems for the existing building.
