 A composite reinforced concrete steel and brick structure, it consists of four levels of roofed tiled pitched and skillion forms punctuated by a faceted flue tower.The stepped forms are clad with sandstone at the sides and architectural concrete panels decorated with pyramidal designs revealing the influence of Ancient Mayan designs on Griffin's work.The free standing building sits high on the northern edge of the park, set on the road that runs along the edge and defined by a series of high sandstone retaining walls.
