It demonstrates in an outstanding way original design qualities of the interwar stripped Classical style.

These qualities on the original (1925) northern facade include the large brick and painted rendered concrete wall planes broken up by 5 vertically oriented, slightly-projecting pavilions, four horizontal bays including the off-centre entrance with a crowning recessed parapet and the 3 glazed colonnaded bays having brick vestigial pillars between the windows.

The original (1925) Report generated 05/04/19 southern Melbourne Road facade is also a distinctive stripped Classical composition with its simple gabled end supported by flanking giant terminal pylons. The later, remaining southern facade is sympathetic proportionally and stylistically to the original sections of the building. 

The six substantial palm trees and lawned areas fronting the Melbourne Road, together with the fences and gates, contribute to the significance of the place.
