ARCASIA orginated initially during the 1967 Commonwealth Association of Architects (CAA) New Delhi Conference.
An urgent need was felt for the establishment of a regional cemtre that would be concerned with environmental design and unity among the six Asian member Institutes of the CAA.
The six Asian Institutes (the founding members) were India, Sri Lanka, Pakistan, Malaysia, Singapore and Hong Kong.
The proposal was for a Center for Environment and Technical Advancement(CETA) and for establishment of an ARCASIA Formation Council.
The First Formation Council (1969-1974) in September 1970 resolved that future assembies of the National Institutes of the Asian region of the CAA and ARCASIA be formally called the Architects Regional Council Asia (ARCASIA).
While reorganizing the need for worldwide associations, the organization was formed to enable closer working relationships between the individual Member Institutes within the region to deal with matters that are or more immediate importance to the region.
Many of the current Member Institutes of ARCASIA already belong to the Union Internationale des Architects (UIA) being an international organization and integral with UNESCO.
In 1970 the Ikatan Arsitek Indonesia (IAI) participated as observer; in 1972 the Institute of Architects Bangladesh (IAB) & the Association of Siamese Architects (ASA) became members; and in 1974 the United Architects of the Philippines (UAP) came as observer and joined in 1977 ad full member.
In 1979, ten years after the establishment of the First Formation Council in Hong Kong, the constitutions for ARCASIA and the ARCASIA Board of Architectural Education (ABAE) were signed at the inaugural meetinf held in Jakarta with the followinf member Institutes in attendance:
The Architects Regional Council Asia became established and the acronym "ARCASIA" wad retained for the new council which is held as a Council of Presidents (or their representatives) of the various national Institutes of Architects in Asia.
