Architectural design is a concept that focuses on the components or elements of a structure. The design of a building is a sequential and iterative process. The first phase involves the definition of the client’s needs. It includes functional, aesthetic, fire and exit safety requirements all to be provided within the limits of available budget set by the client. A conceptual design is then developed and possible building layouts are developed. A final choice is made based on the needs of the client with due consideration of the available budget.
