Architecture is both the process and product of planning buildings and structures. It has evolved out of human needs for shelter and work spaces. Architectural works from historical civilizations like Greece and Rome are often seen as cultural symbols. Architecture began as a craft to fulfill needs and became more refined over time through trial and error. Today, vernacular architecture continues to be important globally. The primary purpose of architecture is to create living and working spaces for societies and individuals. Good architecture provides a sense of balance and efficiency to make people's lives more productive and comfortable.
