Overview
The mezzanine floor often projects itself from the walls and does not completely close the view of the ceiling from the floor immediately below. In short, a mezzanine floor and the floor below it share the same ceiling. Mezzanine floors are often located between the ground floor and the first floor but it is not unusual to have mezzanine floors in the upper floors of a building.
In Palladian architecture the mezzanine is a low upper floor, usually for servants and/or storage. In stadiums, the "mezzanine" level is a term often used for premium or "club level" seating, typically just a few rows deep and hanging from the upper tier, affording an unobstructed view of the playing field.
In transit stations, a mezzanine level is often encountered between the station's entry elevation and the platform level, where the service is boarded. This may contain the area where fares are paid, or provide access to different service platforms. The term is used particularly where an open concept of station allows the platforms to be viewed from that level.
