We previously showed the Travelpod, an experimental prefab from Travelodge, and thought it was an interesting one-off. We were wrong; the company is looking seriously at prefab hotels and is building their first in the west London district of Uxbridge, right now. it is like a pop-up prefab:

"It could facilitate the creation of hotels on a temporary basis at times of peak demand in certain locations -- such as festivals or sporting events," the firm's director of property and development Paul Harvey said. "A temporary structure to fill such a need would differ to the design of a permanent hotel but it could be built in as little as 12 weeks and removed quickly at the end of the event when the need is gone."
