It’s just a concept, so don’t get your hopes high! :)
The Cloud is a speculative design for a resort city elevated 300 metres in the air above Dubai and is just supported on slanting legs resembling rain. It is designed by Nadim Karam, a Lebanese architect. It is a horizontal presence on an elevated platform, an antithesis to the sum of skyscrapers spreading over the entire region. This looks scary :P
