Type refers to an object belonging to a class with similar characteristics. In architecture, type refers to objects having the same formal structure or use. Typology, in turn, means the study of types and the analysis of their characteristics. In order to understand the work of architecture, we need to understand the concept of type. The architectural work can either be characterized by a condition of individuality or be considered as a class of repeated objects. The concept of type is based on the grouping of objects according to certain essential structural similarities. For example, when we talk about skyscrapers, we are actually referring to something huge. Architecture is not only defined by types but is also created through them. The concept of types is also seen as a transformation process, where type is seen as the framework within which change occurs. In this process of change, the architect may extrapolate from the type, modify its usage, or different types may overlap to form a new type. The architect characterizes architecture as a discipline, when an architect is able to describe a new set of formal relationships through a new type. According to Vidler, architecture has the capacity to generate a complete image or structure comprising subject-object relationships within the city, and which then offers an experience of real, historical life within what is still a irreducibly structural design modality, or the critical function of typology. Therefore, to understand the subject of type is to understand the character of the architectural object. Indeed, architectural objects are no longer thought of as unique and isolated events, because they are limited by the world that surrounds them, including its history...... middle of paper ......h to explore the idea. Le Corbusier used architectural rules for the new architecture, prescribed in his "five points", each of which departs from and overturns an existing practice. The modern movement lacks symbolic content and offers two opposing views of the city. Modernists like Léon and Krier who followed neoclassical traditions returned to Durand's concept of type. Following the failure of the modern architectural city, an alternative to the typology and the historic city was proposed by the neo-rationalists. The return to the historic city as an urban model par excellence has allowed various developers to revalidate it as a permanent but functionally transparent architecture. The type is considered a tool that has allowed architects of each generation and theorists to keep the role of architecture up to date..
