( CNN ) -- Traditionally , hotels are built with the hope they 'll have staying power . For a new breed of accommodation , however , long-term is passe . The last two years has seen a proliferation in the number of pop-up hotels -- housed in anything from tepees to old shipping containers . Many are making their way in places traditionally off-limits for traditional hotels . Mark Sorrill , the founder of the UK-based The Pop-Up Hotel , has set up accommodation in the form of luxury tents ( and in some cases yurts , shepherd huts and Airstream mobile homes ) at some of England 's most spectacular properties . In August , for example , he 's partnering with Heritage England and moving his operation on the grounds of the Osborne Estate , a sprawling 19th century manor that was built as a summer residence for Queen Victoria and Prince Albert . `` As lovely as conventional hotels can be , they are effectively a series of boxes stacked on top of each other , insulating guests from the environment . I wanted to throw this whole concept up into the air and see how it fell , '' he says . `` I wanted to create a hotel that could really connect with the environment where it was positioned . '' Infographic : The price of business travel . The Pop-Up Hotel is also popular on the festival circuit . In fact , the first one launched at Glastonbury , the UK 's largest music festival , two years ago . Then , it only offered 20 rooms . This year , its rolled out 130 , and was fully booked . `` Guests seem to really appreciate that if you were to come and stay with us again in a different location , it would be a different holiday experience , '' he says . Booking is n't necessarily cheap -- tents at the four-day Glastonbury festival start at $ 1,525 . At the same time , just because the walls are canvas does n't mean you 'd be roughing it . Concierge and porter service is usually part of the package and , depending on the event , there are usually accompanying restaurant , bar and spa tents . The concept is gaining traction . Snoozebox is another company that offers portable accommodation , often pegged to major events , such as the London Olympics last year and the G8 Summit in Northern Ireland in June this year . Snoozebox 's rooms are set up in shipping containers , making them easy to transport . That they 're self-contained means they have climate control options , an advantage over The Pop-Up Hotel . China 's high-speed trains attract frustrated fliers . One of the most inventive pop-up concepts , however , has n't been officially launched yet . It is the brainchild of Copenhagen-based architecture firm Pink Cloud , and last month it won the Radical Innovation in Hospitality Award . The company is hoping to simultaneously address two pressing issues plaguing many urban landscapes : vacated office space and insufficient hotel vacancies . The collective , which is made up of partners Eric Tan , Leon Lai and Nico Schlapps , is hoping to make New York its launching point . Tan points out that the office vacancy rate in the city is alarmingly high at 26 % . `` Tenants would rather wait for new high rises to be built than rent the ones leftover from the '60s and '70s , which , unfortunately , the city has a lot of , '' he explains . `` The ceilings are low and the stock seems outdated to potential tenants . '' Meanwhile , New York 's hotel occupancy rate is at 96 % -- almost full capacity . Pink Cloud 's solution is to create temporary hotels in empty office buildings . That way , tourists get a place to sleep for the night and the building owner can finally pull in some rent . Watch : reinventing the hotel breakfast . An entire hotel could fit into 36 boxes , enough to fill a single lorry . When unpacked , they would contain all the makings of a modern hotel room , including beds , sofas , toilets , partitions , plus elements to craft night clubs , restaurants -- even a pool , if requested . `` A traditional hotel can take five to six years to build , from start to finish . With the pop-up hotel , we see it taking two to four weeks , '' says Tan . The beauty of the project , says Lai , is its flexibility . `` If you were to set up in Miami , you could bring indoor swimming pools . In Manhattan , guests might want to watch a boxing match . We could bring in a temporary boxing ring . It all depends on the city and the public , '' he says . The price point , they 're imagining , would also be considerably lower . The average New York City hotel room is $ 350 a night . Pink Cloud 's rooms , meanwhile , would clock in around $ 130 . The company is currently scoping out partners to make the concept a reality . The way Pink Cloud sees it , the hotel could be a savvy marketing stunt for the right brand . For example , says Tan , a major fashion label could use the Pink Cloud model to promote itself during fashion week . `` There 's no reason you could n't have the Prada pop-up , or the Diesel pop-up , '' he says .
The last two years have seen an increase in pop-up hotel chains . Unlike traditional hotels , these can set up at festivals and special events . They are often located on the outskirts of town or near a major highway so they don't require much space to operate.
