[1] Situated on Flinders Lane, within a dense area of Melbourne's CBD, the original 1930s building was concrete-framed and free of columns, with beams spanning 3.8 meter centers from wall-to-wall piers.

It was originally designed with the lane façade rendered in cement with openable steel-framed windows to provide lighting from the side.

In 1989, DCM architects began refurbishing the building, retaining much of these original design elements and adding three new levels to the roof of the existing 8 floors.

They implemented such elements as stainless steel, aluminum, translucent glass, timber veneered panels, and colored planar surfaces.

Colored panels in blues, greens, yellows, oranges and reds were overlaid on the natural cement grey render tones.
