The X-Seed 4000 is the highest structure ever fully imagined. Its intended 4,000 m (13,000 ft) height, 6 km (3.7 mi) broad sea-base, with 800-floor capacity may house 500,000 to 1 million people. It would be the largest building in the world.
The concept was proposed by architect Rafael Vinoly in 1999 as a response to the growing population of China. He suggested that the government should provide land for this purpose. The idea did not go beyond that stage at the time it was proposed.
China's first nuclear power plant will be built in Hainan Island. When it comes on line in 2016, it will be the world's biggest nuclear power station with a capacity of 17 billion kWh per year. It will provide electricity for about one-fifth of the island.
Hainan Island has extensive areas of flat terrain, so it makes sense to build large factories there. However, the island has no natural resources to speak of, and there are concerns about the environmental impact of such a large scale industrial operation.
In fact, many islands around the world were originally part of a single continent. In recent years, they have become independent countries when their governments signed peace treaties with the original country. These include Palau, Micronesia; Marshall Islands, Oceania; and Nauru, Pacific Ocean.

The Council on Tall Buildings and Urban Habitat (CTBUH) has devised two new categories to distinguish these outstanding constructions from conventional skyscrapers: supertall and megatall. Buildings dubbed "supertall" can reach heights of more than 300 meters (984 ft). "Megatall" refers to buildings that rise over 400 meters (1300 ft).
The Burj Khalifa in Dubai is the current record holder for the world's tallest building, at 828 m (2723 ft). It was also the first supertall and megatall buildings. The previous record holder, the 708-m-high (2233-ft)-high Shanghai Tower, was not classified as such due to its height being less than 300 m (985 ft).
Other notable supertalls include the Russian Federation's Gazprom Towers (291 m or 984 ft), the US$350 million World Trade Center Chicago (289 m or 951 ft), and the Kingdom of Saudi Arabia's King Abdullah Financial District (279 m or 945 ft).
The Guggenheim Museum in New York City is the current record holder for the highest occupied floor area ratio (the proportion of space that is used for living purposes vs. parking spaces). It has been listed among the most sustainable buildings by leading environmental groups such as Green Building Council (GBC) and Leadership in Energy and Environmental Design (LEED).
At 829.8 meters, the Burj Khalifa skyscraper is the world's tallest building (2,722 ft)... Structures (historical or current) of 600 m or more in height (1,969 ft)

The Burj Khalifa At 829.8 meters, the Burj Khalifa skyscraper is the world's tallest building (2,722 ft). Guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electrical transmission towers, and bridge support towers are among the structures included. The list is limited to functional buildings over 40 meters high, which were completed after 1990.
The previous record holder was the 828-meter-high Millau Bridge, which crosses the Canal du Midi near Millau, France. It opened in 1994 and is now owned by Alstom. The third-highest tower is the Shinhan Bank Building in South Korea at 275 m (931 ft). It was built in 1997.
The highest antenna is held by the Thaicom 6 satellite, at 228.6 meters (727 ft) above mean sea level (msl) on its launch pad in Thailand. It was used for communications experiments with NASA. The lowest antenna is held by the Netherlands' Radionet Global Navigation Satellite System (GLONASS) station at 3 meters below ground level (bgl).

If erected, the tower would be two miles (3.2 km) tall and 500 storeys tall, with a total height of 3,218 meters (10,558 ft). It is one of the world's tallest buildings and man-made structures, but it will not be erected.

Until 2015, Dubai's Princess Tower was the highest apartment skyscraper in the world. It is higher than the Empire State Building, with a roof height of 1,286 feet. Because it is so tall, clouds can develop beneath the higher levels on occasion. These clouds have been seen by witnesses looking toward New York City.
The building was completed in 1999 and has 72 floors above ground plus a floor of parking spaces. Its total height including its antenna is 461 meters (1,476 feet). The antenna at the top of the tower stretches 328 meters (1,142 feet) and transmits TV signals into four different directions: north America, south America, Europe, and Asia. It is the largest such structure in the world.
Princess Tower is located in the Business Bay area of Dubai, next to the Dubai International Airport. It is one of many high-rise buildings in that part of town.
The average height of all apartments in Dubai is about 14 stories, but some go up as high as 18 or 20 stories. A few high-end buildings are even taller - - one rises 30 stories or more.
In general, apartment buildings in Dubai are quite small - - usually less than 50 stories - - compared to New York which has skyscrapers up to 350 stories tall!
