Changsha’s Vertical City

The Broad Sustainable Building company is taking vertical living to a new level with the construction of a skyscraper that will encapsulate an entire city.

The 220-storied highrise, called Sky City, is scheduled to begin construction next month in Changsha, which is the capital of the Hunan providence in China. At the time of writing, Sky City is to be the world’s tallest building, rising 10 meters above Dubai’s Burj Khalifa, at 838 meters high. The project is also significantly cheaper, costing 17 times less than Burj Khalifa, despite an estimated 90 day-long construction period. The speedy assemblage can attributed to the company’s decision to have sections of the building prefabricated in a factory beforehand.

When finished, the vertical metropolis shall take up only 10 percent of the allotted land space, the rest being devoted to an expanse of lush parkland. In addition to housing, the interior will brim with amenities.  The 1st to 5th floors are to be filled with 5 schools, a hospital, and nurseries. Further above, the 6th to 15th floors will be occupied with bustling office space, serving as workspace to some of the building’s 30,000 live-in employees.

The 16th to 180th floors will house apartments, with room adequate enough for 4450 families, apartments will varying in style and ranging from 645 to 5,000 square feet. Within the residential area, hotel space will accommodate up to 1,000 guests. The building even has its own agricultural system planned, with 930,000 square feet of vertical organic farm space.

The absence of horizontal distance depletes the nuisance of traffic jams, as occupants can instead travel to work and entertainment with the assistance of one of dozens of  elevators. Or, if they fancy to expend a bit more energy, with the use of a six-mile long ramp that ascends from the first to 170th floor.

Outside the indulgent interior, the building’s exterior window shading contributes to a 30 percent reduction in cooling requirements. The 8-inch thick walls, which are triple-glazed and ceramic encased, are responsible for the three-hour fire resistant rate and an earthquake resistance rate up to magnitude 9.

Sky City does, of course, have its critics, a number of whom fear the excessive height of the skyscraper may cause subsidence.

The highrise also poses a greater safety risk in the event of a fire, as currently fire ladders reach a maximum of 100 meters – 738 meters short of the building’s clearance.

It would certainly seem an isolated existence, insofar as the building’s solitary placement from the rest of the providence. However, there is something to be said about going to the office whilst your child flexes their academic muscles only a few meters below you, and heading out at the end of the day for dinner or a movie without the need to take a step outside.

It also doesn’t hurt that the Sky City resident will use only 1/100th the energy of an average citizen.
