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.
