A mezzanine is an intermediate floor in a building which is partly open to the double-height ceilinged floor below, or which does not extend over the whole floorspace of the building, a loft with non-sloped walls. 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.

A loft is a building's upper storey or elevated area in a room directly under the roof, or just an attic: a storage space under the roof usually accessed by a ladder. A loft apartment refers to large adaptable open space, often converted for residential use from some other use, often light industrial. Adding to the confusion, some converted lofts themselves include upper open loft areas.
