The Bath House at Broadbent's Engineering in Huddersfield has been designated at Grade II, for the following principal reasons: * The building is a very rare, possibly unique example of a purpose built bath house for foundry workers * Its continuing function as a bath house has preserved its original purpose in both its layout and its fixtures and fittings as well as its design * The design of the building manifests inspiration from both W Dudok and Frank Lloyd Wright, and achieves a high standard of accomplishment in its interpretation of contemporary architectural influences * The use of local stone for external walls distinguishes it from brick built pithead baths of similar style, and the imaginative use of finishes lends further distinction * The interior survives almost entirely intact, with original wash basins, shower and tap fittings, lockers, floor and wall surfaces, doors and light fittings.
