#26. Tate & Lyle factory, Factory Rd
A long trip on the DLR to get there, but if you’re near a carriage window, you needn’t worry about missing it. You might think it strange that a factory has made my list, but this one deserves to be on it: it’s entirely Wonka-esque. Brooding, masculine, all shoulders and chimneys, towering over the matchbox houses below. It wouldn’t look out of place on the pages of Roald Dahl – in fact, I half wonder if Quentin Blake used it as a reference for his Charlie and the chocolate factory illustrations.
