Before the unicist approach was developed architecture had multiple approaches to solve its tasks in the multiple fields of application.
The unicist approach introduced the approach to architecture based on a unicist structural functionalist approach: unicist because it manages a specific reality as a unified field; structural because it defines the unicist ontological structure of such reality and functional because it uses the ontogenetic maps and objects to manage its functionality.
This requires a sound knowledge of the operational aspects and the nature of the field where something needs to be built.
Architects are individuals who make something exist that did not exist before. They are a sort of creators who have assumed the responsibility that this creation becomes useful, aesthetic and solid.
This role of architects has been socially accepted since they exist, which makes legitimate the fact that their earning be proportional to the value of their creation.
The original role of architects is the field of construction but it extended to those capable of building of any entity that can exist in itself and is useful, aesthetic and solid.
That is why there exist architects in many fields such as product architects, IT architects, sound architects, marketing architects, business architects, etc.
Vitruvius was the one who was able to describe and define their role in the 1st Century B.C. He was the one who described the ontological structure of their function.
The unicist approach to architecture includes the need to know the ontological structure of what is being built in order to ensure its utility, aesthetics and solidity.
Unicist Architecture is a structural functionalist approach to building. This building may or may not emulate nature. What the architects need to manage is their integration in a unified field with the project they are dealing with defining its utility, aesthetics and functionality.
NOTE: The Unicist Research Institute was the pioneer in complexity science research and became a global decentralized leading research organization in the field of human adaptive systems. http://www.unicist.org/turi.pdf
