The American Institute of Architects, established for over 150 years and representing more than 80,000 members worldwide, is the most influential voice for the architectural community in the United States.

Through its growing number of international members and chapters, the AIA is gaining influence throughout the global architectural community.

In 1990, a group of American architects living and working in the United Kingdom came together to establish a local chapter in London and in 1992, the AIA UK officially became the first international chapter of the AIA. The UK chapter has close to 200 members throughout the country. What began primarily as a social vehicle soon grew into a professional organization actively participating in the larger architectural community.
