This is one big curtain — 19 metres high. Constructed for a yacht construction and maintenance facility at Hemmant, Brisbane, the curtain provides an economical and space-saving means of fully opening or closing one end of the building.

The curtain was constructed of shade cloth reinforced with webbing, by Copelands+Pickers. The curtain can be opened and closed from ground level by hand-operated winches. The curtain track is curved so that the full height of the building can be utilized. Osborn Lane engineer Charles Ting developed an open and closing mechanism which operates on the curved track, and does not obstruct the full height opening.
