It used to be that guests associated hotels with a physical address: a static, brick-and-mortar establishment to which they could always return.

That concept is becoming outmoded, as evidenced by the finalists of this year’s Radical Innovation Award, which highlights unique concepts in hospitality design.

The winner of the annual award receives $10,000 to further their idea and will be announced on October 5.

“We don’t need another new brand that can be replicated 200 times. We need qualitative improvements in hospitality concepts and travel experiences for the industry,” says John Hardy, founder of Radical Innovation.

HOK, one of this year's finalists, imagines a world where hotel pods will be delivered by drone.

This year’s two professional finalists each submitted a pop-up concept whereby rooms are set up in hard-to-reach or underutilized spaces.

Driftscape, submitted by the Toronto office of award-winning architecture firm HOK, is a mobile, self-sustaining hotel delivered by drone.

It can be dropped off anywhere, even in the most remote stretches of the planet.

Driftscape consists of several modular units, including a food and beverage element and a single guestroom that offers up 360-degree views.

Paris-based MM Architects, another finalist, submitted a pop-up concept called Nesting, which introduces customizable units which – like Lego bricks – can connect and grow, and be placed into parks and other underfunded public spaces.

MM Architects won the Grand Prize in 2012, with their concept Koi, a bridge-hotel hybrid that is currently being considered for development in London.

This year’s student finalist, Juan Orduz from the University of Nevada, submitted a concept that is, literally, out of this world.
