In Chapter 1: "The General Principles of Architecture", Laugier divides and analyses buildings into five main "articles": the column, entablature, pediment, the different storeys of architecture, the windows and doors. In Article 1, for example, Laugier makes four general rules for the construction of columns, one of them being that the column "must be strictly perpendicular, because being intended to support the whole load, perfect verticality gives it its greatest strength." To Laugier, these articles emphasised the fundamental components of a building and what he identifies as their core necessities - that is, The Primitive Hut model. Laugier emphasised the point that nature provides the rules for architecture.
