A mezzanine (or in French, an entresol)[1] is an intermediate floor, similar to a balcony, in a building whose center is open to the double-height ceilinged floor below. Mezzanines may serve a wide variety of functions. Industrial mezzanines, such as those used in warehouses, are temporary or semi-permanent structures.

Definition[edit]

A mezzanine is an intermediate floor (or floors) in a building which is open to the floor below.[2] It is placed halfway up the wall on a floor which has a ceiling at least twice as high as a normal floor.[3] A mezzanine does not count as one of the floors in a building, and generally does not count in determining maximum floorspace.[2] The International Building Code permits a mezzanine to have as much as one-third of the floor space of the floor below, and local building codes may vary somewhat from this standard.[2] A space may have more than one mezzanine, so long as the sum total of floor space of all the mezzanines is not greater than one-third the floor space of the complete floor below.[2]

Mezzanines help to make a high-ceilinged space feel more personal and less vast, and can create additional floor space.[4] Mezzanines, however, may have lower-than-normal ceilings[1] due to their location. The term "mezzanine" does not imply a function, as mezzanines can be used for a wide array of purposes.[5][6]

Mezzanines are commonly used in Modern architecture, which places a heavy emphasis on light and space.[3]

Industrial mezzanines[edit]

In industrial settings, mezzanines may be installed (rather than built as part of the structure) in high-ceilinged spaces such as warehouses. These semi-permanent structures are usually free-standing, can be dismantled and relocated, and are sold commercially. Industrial mezzanine structures can be supported by structural steel columns and elements, or by racks or shelves.[7] Depending on the span and the run of the mezzanine, different materials may be used for the mezzanine's deck.[8] Some industrial mezzanines may also include enclosed, paneled office space on their upper levels.[7]

Industrial mezzanines are typically not constructed of wood. When they are, the mezzanine is usually used solely for storage.[9]

An architect is sometimes hired to help determine whether the floor of the building can support a mezzanine (and how heavy the mezzanine may be), and to design the appropriate mezzanine.[8]
