If you want some really cool buildings, you should go to Dubai.
Among them are the soon-to-be Hydropolis, the second undersea hotel, and larger than the first by such a large amount it's not even funny (the first had something like 5 rooms):
& at night:
Dubai is also home to the Burj al-Arab, the world's tallest hotel, and the world's only "7 star hotel and most luxurious hotel in the world. It stands on an artificial island in the sea.":
But wait, there's more!!
The Burj Dubai, which began construction in 2005 and will be complete sometime this year. At an estimated height of over 800 meters, it will easily be world's tallest building when finished. It will be almost 40% taller than the current tallest building, the Yaipei 101.
And finally, the Trump International Hotel & Tower, which will be the centerpiece of one of the palm islands, The Palm Jumeirah:
Dubai is said to currently have 15-25% of all the world's cranes due to all of the construction currently underway.
The Dubai waterfront, when completed, will become the largest waterfront development in the world ..
Currently, the largest amusement park collection in the world is Walt Disney World Resort in Orlando , which is also the largest single-site employer in the United states with 58,000 employees. Dubailand will be twice the size, and is already well under-way and is open to visitors. Dubailand will be built on 3 billion square feet (107 miles^2) at an estimated $20 billion price tag. The site will include a purported 45 mega projects and 200 hundred other smaller projects.
Some of the tallest buildings in the world, such as Ocean Heights and The Princess Tower , which will be the largest residential building in the world at over a 100 stories, will line the Dubai Marina.
The UAE Spaceport would be the first spaceport in the world if construction ever gets under way. I'm not joking...
Some other crazy stuff... The Dubai Metro system, once completed, will become the largest fully automated rail system in the world. The Dubai World Central International Airport will become the largest airport in size when it is completed. It will also eventually become the busiest airport in the world, based on passenger volume. There are more construction workers in Dubai than there are actual citizens.
