A canal warehouse is a commercial building principally associated with the expansions of canals from 1761 to 1896. This type of warehouse derived from coastal predecessors, had unique features: it had internal water filled canal arms that entered the building, it was multistorey with canal access at one level and road and even rail egress at another, and has a hoist system powered by a water wheel or at later stages steam. Canal warehouses were transhipment warehouses, holding goods until they could be shipped out to their next recipient.[1]
The first true canal warehouse was the Dukes Warehouse,[1] at the Bridgewater Canal Basin in Castlefield, Manchester built in 1761. It has been demolished, but two later warehouses at Castlefield have been restored.[2] The later Portland Basin warehouse, was built in 1834 by the architect, David Bellhouse. It has three shipping arms, and continued to be used as a storage warehouse after its serving canal became disused.[3]
David Bellhouse was responsible for designing the first railway warehouse at Liverpool Road railway station in 1830, and the features of the canal warehouse were incorporated into a transhipment warehouse for this new form of transport.
