Overall, the museum underwent significant redevelopment, with the garden being removed to make way for new facilities such as fountains, a restaurant, and additional shops, while the exhibition areas remained largely unchanged.
In 1998, the central part of the museum consisted of a café and a garden. By 2008, however, the garden had disappeared, replaced by two fountains and a new toilet block to the right of the café. A restaurant was also constructed to the left, occupying part of the former exhibition area.
