The New York-based charity guru Cameron Sinclair was pipped to the prestigious prize by James Hewlett, who produced the images, storyboards and designs for the imaginary band.
Sinclair founded the charity - which now has a vibrant London chapter - in New York in 1999 in an attempt to develop design solutions for the humanitarian crisis unfolding in Kosovo.
After a slow, cash-strapped formative few years, Architecture for Humanity has come into its own over the past 24 months, with extraordinary projects under way - many in disaster areas.
Among the areas to have benefited recently were the Tsunami-hit zones of the Far East, earthquake-affected Kashmir and hurricane-struck New Orleans.
