Architecture is a social art.  Architects sometimes construct and construct buildings with personal ideas, but most buildings are designed according to social needs. Architects are generally expected to design a specific building in a specific location. Many people are involved in the process of building a building; there is plenty of capital and resources and other specialties except architects. Building laws and regulations also limit architectural decisions. Designing an architectural building is the ultimate decision maker, but the community's demands, laws and demands of the employer affect their decisions. The same goes for the appearance and facade of the buildings. Even today, welcomed by new and unfamiliar exterior experiences, there are rules in many cities, especially historic cities, to accommodate new buildings in urban form and to follow a common language.
