Second 100 Interior Design Giants 2012 Methodology

The second installment of the two-part annual business survey of Interior Design Giants comprises the second 100 largest firms ranked by interior design fees for the 12-month period ending December 31, 2011. The first 100 Giants firm ranking was published in January. Interior design fees include those attributed to:

1. All types of interiors work, including commercial office, hospitality, retail, health care, and residential.
2. All aspects of a firm’s interior design practice, from strategic planning and programming to design and project management.
3. Fees paid to a firm for work performed by employees and independent contractors who are full-time staff equivalent.

Interior design fees do not include revenues paid to a firm and remitted to subcontractors who are not considered full-time staff equivalent. For example, certain firms attract work that is subcontracted to a local firm. The originating firm may collect all the fees and retain a management or generation fee, paying the remainder to the performing firm. Amounts paid to the latter are not included in fees of the collecting firm when determining its ranking. Ties are broken by the dollar value of products installed. The data was compiled and analyzed by the Interior Design market research staff in New York, led by Wing Leung, research director.
