There are lot of "pod" hotel concepts around. It's one of those things that every young design/architectural practice likes to have a go at for its portfolio. The use-cases for these things are obvious, airports, train stations, exhibition halls, shopping malls, even temporary hostels or emergency shelter. Economic conditions notwithstanding it's a simple fact that we are traveling more and that the time spent waiting around in terminals is getting longer and more unpleasant. The promise of privacy and proper sleep is compelling. One architectural practice that has honed its pod concept into a refined, practical and importantly a patentable reality over a the years is Arch Group of Moscow. The high level of interest shown in the company's first working installation means that it looks like this tenacity will pay off.
