Abstract: There is proposed a towable expandable accommodation or storage assembly that includes a floor portion that is affixed to or supported on a drawbar, wherein an expansion portion is configured to be pivoted to one side of said floor portion to form at least one wall when the assembly is being used for the purpose of accommodation or utility. The assembly may provide a collapsible ablutions cubicle or kitchen area that can be reduced in size during transportation of the assembly. In this way, the assembly can be towed to a site and expanded to provide an expanded living area. Furthermore, the configuration of the floor portion means that grey water can be captured for the ablutions cubicle or kitchen area for storage in a tank or to be directed to a drain.
