A loft is an apartment that consists of one large open space
with high ceilings and exposed construction elements such as
pipes, brick, and support beams. Floors are wood or concrete.

Bonus words: True lofts, known as hard lofts, are located in
buildings that originally had commercial or industrial purposes,
e.g., the former warehouses of Manhattan’s SoHo and NoHo
districts, where the concept of loft-living began.

A soft loft is an apartment in a new building designed to
resemble a hard loft.
