What next for plus-five-star hotels? The answer might lie in this creation - the Apeiron, in (yet again) Dubai. Although work on the self-proclaimed six-star hotel hasn't actually started yet, the British architecture firm Sybarite has already proclaimed it a top candidate for the hotel of the future.
The plans include an artificial jungle, complete with butterflies, on the top two floors plus, less exceptionally these days, an underwater restaurant and an art gallery. Taking exclusivity to a new level, the hotel, with a rumoured $500 million budget, will only be accessible by helicopter and boat.
