Located on the Isle of Dogs, Millwall Docks were best known for the grain trade. Other supplementary trades included timber, wine, liquor, fruit and vegetables.

The success of the grain trade at Millwall prompted civil engineer, Magnus Mowat, to invent new handling and storage methods for the dock.
Three pneumatic grain elevators were erected on platforms 15 metres away from the jetty. These could discharge directly into barges or to the granary.

The unique brick-built granary was 76 metres long, 30.5 metres wide and was designed to hold 24,000 tons of bulk grain. It had 11 floors for storage and inspection and a delivery floor and basement. The granary was divided into five compartments with vertical firewalls and had a 20,000 gallon (91,000 litre) water tank on the roof for fire fighting and windows for ventilation.
