Architecture is the art and science of designing buildings known as Architectural Design. A wider definition would include within its scope the design of the total built environment, from the macro level of town planning, urban design, and landscape to the micro level of furniture and product design.
Architecture is that set of design artifacts, or descriptive representations, that are relevant for describing an object, such that it can be produced to requirements as well as maintained over the period of its useful life.
Architectural design is a multi-disciplinary field, including mathematics, science, art, technology, social sciences, politics, history, philosophy, and so on. Rationalism, empiricism, structuralism, post-structuralism, and phenomenology are philosophical directions that influence architecture.
It is a concept that focuses on the components or elements of a structure or system and unifies them into a coherent and functional whole, according to a particular approach in achieving the objective under the given constraints or limitations.
