Mezzanine Floor

A mezzanine is an intermediate floor (or floors) in a building which is open to the floor below. It is placed halfway (mezzo means 'half' in Italian) up the wall on a floor which has a ceiling at least twice as high as a floor with minimum height.A mezzanine is a partial floor with an area 25% or less of the floor it is located on. Other construction features — such as whether the area in question is a balcony or a closed-in area — do not play a role in determining if the area is a mezzanine.
