"The Rootes car showroom and workshops, Mill Street, Maidstone, is designated at Grade II for the following principal reasons: * The building is of architectural interest as an example of a Modernist motorcar showroom and workshops which retains a significant proportion of its original fabric. * The building is of architectural interest due to its grand scale, town-centre location and picturesque setting adjacent to the Len mill pond, which distinguishes it from other buildings associated with the motorcar industry during this phase of early motoring. * The building is a prominent manifestation of a hugely successful British car manufacturer, built in a period when the expansion of car ownership was having a revolutionary impact on the physical and social fabric of the nation."
