Like nourishment and raiment, shelter is one of the most elemental of human needs. Curiously, food, clothing and housing are recognised in the Universal Declaration of Human Rights quite incidentally: they are numbered among the components of an adequate standard of subsistence (see UN 1948: Article 25). A specific right to a home is nowhere declared. The assumption it would seem is that citizens may secure their homes at will, subject only to the means of payment, and that the primary source of protection lies in civil and not social rights. None the less, where British social legislation does relate to housing, it creates four kinds of rights.
