Architecture
Architecture is both the process and the product of planning, designing, and constructing buildings or any other structures. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.
Social
Living organisms including humans are social when they live collectively in interacting populations, whether they are aware of it, and whether the interaction is voluntary or involuntary.
Social Science
Social science is a major category of academic disciplines, concerned with society and the relationships among individuals within a society. Social science as a whole has many branches, each of which is considered a social science. The social sciences include, but are not limited to: anthropology, archaeology, economics, history, human geography, jurisprudence, linguistics, political science, psychology, public health, and sociology. The term is also sometimes used to refer specifically to the field of sociology, the original "science of society", established in the 19th century. For a more detailed list of sub-disciplines within the social sciences see: Outline of social science.
Architecture
Architecture differs from a work of art, which can be displayed in different settings and the subject-matter, form and meaning will remain unchanged. The physicality of any built structure can be altered over time as additions and alterations are made. Moreover, a building or work of architecture can change its function as it meets the different demands of its occupants, although its exterior appearance may be unaltered. And its meaning may change depending on the nature of the context. This reveals some of the problems of interpreting historic architecture from a modern-day perspective as the physical changes and different cultural contexts transform the object.
