IDEA Office (IO) works on design at all scales, ranging from graphic design to installations and industrial design, to architecture and urban planning. The firm (formerly COA, 1986-2009) was launched in 2009 in Los Angeles by architects Eric A. Kahn and Russell N. Thomsen, who are also senior design faculty at SCI-Arc.

Recent works include a permanent installation at Walt Disney Concert Hall and a new building at West Los Angeles College. The work of IO has been published in numerous journals and books, and a monograph of the work of COA was published in 1998 as part of the Contemporary World Architects series. The work is also part of the permanent collection of the San Francisco Museum of Modern Art.
