Platform or balcony projecting as a partial, intermediate storey between the floor and ceiling of a full-heighted space. The mezzanine (from mezzo, Italian: ‘half’ or ‘middle’) is used to maximize usable interior space, especially where altering the structure to construct additional floors is not possible. In late medieval Italy, the mezzanino appeared in civic buildings like the Palazzo Vecchio town hall, public halls, and in Venetian palaces, mainly as storage and for housing servants. In nineteenth-century Parisian mansions and apartments, the entresol (French, ‘inter-storey’) served as additional living space or storage. Buildings like the Wainwright Building (1891) and the Glasgow School of Art (1909) used the mezzanine as a visual and spatial connector. However, Le Corbusier’s projects such as Villa La Roche (1925), Unité d’habitation (1945) and Villa Shodhan (1954) — popularized the mezzanine as a functional and aesthetic device in twentieth-century modern housing. It finds continued use in modern warehouses, workspaces, and residences.
