( CNN) Commissions, with their long lists of client requirements, don’t always let architects experiment. Competitions, on the other hand, allow them to toss out the client briefs and generate something game-changing.

“It began as an experiment because I wasn’t watching a lot of ingenuity in the inn business, ” tells John Hardy, CEO of The John Hardy Group, the growing consultancy behind the annual competitor. “I thought that a lot of the most creative notions came from people who were not in the mainstream hotel industry.”

The competition has attracted an increasing number of sophisticated submissions from around the world.
