The chimney was stated to be in Warwick St, so it wasn't the same site as Devonshire house, but on hte opposite side of deritend. as i undertsand it the custard , blancmange etc were made on the Devonshire house site, and it was the admin block also, but the coffee was made at the other site. This may be because they didn't have enough space on the main site, or possibly to reduce contamination of the more delicate flavours of the custard with coffee. The reason I suggest this is that i understand that at one time the Somerdale (Frys/Cadbury) factory made pepperminmt products in one building so as to reduce the chance of contaminating other products with peppermint
