Many of Whiteread's works are casts of ordinary domestic objects and, in numerous cases, the space the objects do not inhabit (often termed the "negative space") — instead producing a solid cast of where the space within a container would be; particular parts of rooms, the area underneath furniture, for example. She says the casts carry "the residue of years and years of use". Whiteread mainly focuses on the line and the form for her pieces.
