The RACS building has deco relief showing cars, trains and ocean liners in the style of the time.
The Royal Arsenal Co-operative Society was formed in 1868, and was a consumer co-operative that began in a room in Plumstead and expanded in the next hundred years across the south-east.
This building was one of the co-operative's department stores.
