In 1821, the archaeological cabinet was moved to a new wing of the Museum of Natural History. Reuvens was unhappy with this location as well though, because it was much too small for the growing collection and because the windows provided far from enough light. In 1824, Reuvens was offered some more room of the Museum of Natural History, but Reuvens refused the insufficient extra space and proposed an entirely new building designed especially for the National Museum of Antiquities, which would also give him a lecture hall, restoration facilities and other required rooms. Reuvens plans for this new building would prove much too expensive unfortunately.
