The list is compiled from data gathered by UK communications agency Camargue on behalf of BD.

In 2007, the number of part 3 qualified architects at HKR increased to 157 with a total of 255 staff. Since the survey was completed in September 2007 HKR has sustained its growth and now has over 300 staff across the practice’s six international offices.
