However, the term is often used loosely for the floor above the ground floor, especially where a very high-ceilinged original ground floor has been split horizontally into two floors.

Mezzanines may serve a wide variety of functions. Industrial mezzanines, such as those used in warehouses, may be temporary or semi-permanent structures. Mezzanines can be found in modern architecture as well.
