These futuristic cities are housed inside a single, gigantic building

The evolution of cities may be a lot weirder than you think. Instead of sprawls, they may become ultra-high density constructions that look more like one gigantic building. Here are some incredible plans for buildings that will one day be metropolises.

Crystal Island (designed by Norman Foster for Moscow, 2007)

These futuristic cities are housed inside a single, gigantic building

The 1,476 ft (450 m) high structure doesn't want to be the highest, but it has a "second skin" to shield the structure from Moscow's weather and could minimize the winter heat loss. The complex would use renewable energy sources. It will be completed in 2014, according to the original plans, but due to the global economic crisis the whole project was postponed.

Dubai City Tower or Dubai Vertical City (designed by Meraas Holding, 2008)

These futuristic cities are housed inside a single, gigantic building

If ever constructed, the 7874 ft (2400m) high building will have 400 habitable stories and a 1312 ft (400m) high energy-producing spire on the top. The main elevator will be a really fast one, it could travel local inhabitants with an amazing 125 mph (201 km/h) speed. The energy will come from renewable sources including wind, thermal and solar energy.

Tokyo Tower of Babel (designed by Toshio Ojima/Waseda University, 1992)

These futuristic cities are housed inside a single, gigantic building

If the construction begin, it took 100 to 150 years to complete this unbelievably high (32,808 ft or 10,000 m) tower, and it could cost about $306 trillion. It's big enough to 30 million people live inside.

It would have included 528 stories and nearle twice as tall (5,280 ft or 1,610 m without the antenna spire) as the Burj Khalifa. The famous architect began planning this in the 1920s, but only described in his 1956 book A Testament.
