LOFTS
A loft is a building’s upper storey or elevated area in a room directly under the roof (American usage), or just an attic: a storage space under the roof usually accessed by a ladder (primarily British usage). A loft apartment refers to large adaptable open space, often converted for residential use (a converted loft) from some other use, often light industrial. Adding to the confusion, some converted lofts include upper open loft areas.
COMMERCIAL LOFT
A commercial loft refers to upper storey space, usually in a commercial or industrial building with higher ceilings; a second storey area for storage or offices above may be added within the original space used by a previous business occupant, effectively becoming a mezzanine area within the commercial loft space. Such adaptation of loft space, can result in better operating efficiencies for ongoing light industrial, commercial and work/live use.
LIVE/WORK LOFT
A Live/work loft is a residential unit located in a commercially zoned building that has either been issued a certificate of residential occupancy or meets specific criteria making it eligible for the protection of loft laws, which vary state by state.
