F for Floor

The floor looks like it was laid down wet, as parts of the surface are rippled like the sea just fifty feet below. It is a bituminous material about two inches thick, laid onto the bare steel. Partition walls, fixtures and fittings have very slowly sunk into it; leaving the impression of long gone chair, table and bed legs, lockers and other less readily identifiable objects. It is a ghostly map, in grey relief.
