The Department of Decorative Arts and Design organizes sales by selecting  'broad and diverse types of objects: furniture, lighting, ceramics, glass and sculptures, made in the early years of the 20th  century up to the present day. From Art Nouveau, through Art Déco and the various expressions of Modernism, to  industrial and contemporary design.

The department, which is characterized by the accuracy of the documental research and material analysis, features numerous auctions every year dedicated on the one hand to the decorative arts and design of the 20th century and, on the other, to the so-called Modern Antiques. 

The  Decorative Arts and Design of the 20th century auctions are held once or twice a year  and propose iconic and rare works of the 20th  century.

Among the most important achievements of the last editions, are the furnishings designed by BBPR, which has set some records, works by Guglielmo Ulrich, Paolo Buffa, Marcello Piacentini, the Studio Terragni.
And again, the Murano glass by Tomaso Buzzi and Carlo Scarpa for Venini, by Ercole Barovier and Flavio Poli, and the ceramics by Ettore Sottsass and Nanni Valentini.

The Modern Antiques auctions are held on a quarterly basis and include ceramics, glass and furniture, mostly mass-produced, but with a historic flair acceptable to a wide audience.
