Test Tube is a retail store with a difference, located near the Mount Lawley Cafe strip. The homewares store sells very unique, contemporary and quirky products, which is reflected in the stores colour and theme. One of the stores main features is a multicolored timber wall that extends up one side of the store and curves onto the ceiling. This element was featured at the Dulux colour award in 2007. The design for the store was produced by Matthews Architecture and constructed by Habitat 1.
