A Brief History of Reinforced Concrete Buildings
Early adopters of reinforced concrete frames (who were exempt from building control) included the railways (especially for goods sheds) and the Post Office. Gilbey's gin warehouse (NHLE 1113236) of 1894 is the earliest known building on the List with a full reinforced-concrete frame, although this is of a relatively crude type.
