Designed by the eminent architect, Charles D'Ebro in his favoured Venetian Gothic manner, Gothic Chambers was one of the small number of large commercial designs to go Gothic instead of following the prevailing Italian Renaissance derivatives favoured for most city businesses. The building included a Bourke Street shop and three warehouses, with upper-level offices. The long occupation of saddler Alex Morrison on the ground floor recalls the massive and historic Kirks horse bazaar (established by James Bowie Kirk, late 1840s) that was once located next door and had set the occupancy patterns for the area since the gold rush.
