Because it's all about design. But it's also about our Members, professional growth, and shaping the future.

Because you can become part of something greater.

For more than 10 years, the International Interior Design Association has been working to promote Interior Design through the excellence and knowledge of our Members. In 1994, we combined the Institute of Business Designers, the International Society of Interior Designers, and the Council of Federal Interior Designers to create an international organization that represents the diverse profession to interior design.

We strive to advance our profession, while also cultivating diverse leadership and advocating for exceptional design.

IIDA has more than 12,000 members in nine specialty Forums in 30 Chapters around the world committed to enhancing the quality of life through excellence in interior design and advancing interior design through knowledge. By becoming a Member you are making the decision to be an informed member of the design community.
