The collections of industrial design, and 20th century furniture and household accessories after designs by Czech and foreign architects and designers is the youngest collection currently being built. It contains examples of Czech mass products from the era of the first Czech Republic after designs by Jan Vaněk, Ladislav Žák, H. Kučerová-Záveská, and others.
The inter-war years are documented by exhibits which were awarded various prizes in competitions and exhibitions. International design is represented by inter-war and post-war work by Scandinavian and Italian designers, among them a small collection of plastics acquired at the end of the 60s.
The use of new materials and technologies is reflected in the shape of these mass produced artefacts. Replicas of designs by representatives of the international avant-garde are also found in these collections: work by Le Corbusier, Ludwig Mies van der Rohe, Marcel Breuer, Gerrit Rietveld, Alvar Aalto, Charles Eames and others.
