IIDAについて / The IIDA Story

About International Interior Design Association - IIDA

IIDA is a professional networking and educational Association of 13,000 Members in 10 specialty practice forums and 33 Chapters around the world. IIDA, with respect for past accomplishments of Interior Design leaders, strives to create a strong niche for the most talented and visionary Interior Design professionals, to elevate the profession to the level it warrants, and to lead the way for the next generation of Interior Design innovators. The Association provides a forum to demonstrate design professionals’ impact on the health, safety, well being and virtual soul of the public, balancing passion for good design and strategy for best business practices. IIDA stands at the intersection of passion and strategy where designers create extraordinary interiors and experiences.


IIDA was founded in 1994 as the result of a merger of the Institute of Business Designers (IBD); the International Society of Interior Designers (ISID); and the Council of Federal Interior Designers (CFID). The goal of the merger was to create an international association with a united mission that would represent Interior Designers worldwide. Since that date, IIDA has worked to convene communities of Interior Designers across regions and specialties representing the interests for the entire community. In Japan, ISID was first established in 1982.
