Sure they can. I'm still waiting for a project announcement utilizing a bundled tube system comprised of triangular or hexagonal prisms (most ideal shapes along with rectangular). The Burj Khalifa had a hexagonal core, and if it's primary goal wasn't stomping Taipei 101's height (which it did very well ), a hexagonal bundled tube system would have been the wisest since the tube system is the strongest system available thus far. Expansion on Khan's idea for the Sears is inevitable, and we should see many more using it in the future. Ping An is currently utilizing the system in a 3x3 grid like Sears, yet with today's technology, whereas Sears' construction methods were a bit dated compared to the WTC's in the '70s. 4x4 grids will be the next big thing, and will be used very soon for mega projects like this one. Just because materials are prefabricated now doesn't mean they must be put together in relatively simple shapes.

New version of my model with corrected height, and including spire:

(click for larger)
Regarding the floor count (202), Maybe the new design just has a few less floors than the previous version.
If you go to the first page, you will see the older version, which has some small floors on the top which this one doesn't have, so I think the new floor count is 202 floors.

By now it's only a technology in proof, that's why I don't complain about the simple design of this tower, because it's just like a prototype, I guess if it succeses, this technology will evolve and become more complex and flexible.
This technology is yet in this stage:

We don't know yet how it will evolve, but you've already know how the picture above evolved, so everything is possible.

I doubt it will be. Kingdom Tower will surpass it within a few years. Now, what lies beyond that horizon is something unbeknownst that only time will reveal.

I also heard that they are going forward. A friend working on the steel industry, told me that their office in China will supply them the high-strength steel for the construction.

Great to here, but what happened with that

Changsha is a mid-sized provincial city?

Changsha's 7 million people is NOT mid-sized, that's like on the order of NYC, 2X Los Angeles, and 3X Chicagos.

Not really. Chinese cities are dense and also have very large footprints. There are dozens of cities and metro areas that have 5+ million people.

That could be the real vanity goal - first to 200+ floors.

Amazing.
Can you add more buildings to this comparison?

Zhang doesn't plan on stopping at 202 stories, either. He has a vision of a structure three times that size. What are the odds this 636-story building ever breaks ground? Terril Yue Jones asked him. His response:


"One hundred percent! Some say that it’s sensationalism to construct such a tall building. That’s not so. Land shortages are already a grave problem. There’s also the very serious transportation issue. We must bring cities together and stretch for the sky in order to save cities and save the Earth. We must eliminate most traffic, traffic that has no value! And we must reduce our dependency on roads and transportation."
So, is Zhang about to be the 21st-century reincarnation of Le Corbusier, advocating revolutionary densities and self-contained super-blocks but with a transit-oriented perspective colored by climate change?

--

I wonder, will we see this in our lifetime? Or perphaps 600+ floors is as common as 80+ floors is now when I'm 70. I can't wait to see what the future has in store for us

I think we'll definitely gonna see such a building in our life time. Technological progress gets faster each year and has reached unprecedented levels. Also, he has very good points which hint that skyscrapers might start playing a much wider role than what we currently see once land for growing food and fossil fuel will drop to alarming levels

I will eventually, but not now. My brother is currently borrowing most of my RAM, so if I add any more buildings, my computer might crash!
Also, I should probably be doing some study for uni.

My point was that the figures for US cities were hopelessly inadequate. Metro areas are much bigger than stated there.

Well, the Chrysler Building had the same thing, it was the wtb for a very short time but it's still iconic because it's still considered beautiful, I have to see if that happens with this building.

From Demographia... articule below.
Los Angeles v. Changsha: Getting the Population Comparison Wrong

Thank you for the reference on the ghost cities fairy stories. A correction is in order, though. Changsha is nothing like twice the size of Los Angeles. This assumption comes from a misunderstanding of the difference between western terms and Chinese terms as translated into English. The term "city" is commonly used in English to denote the Chinese term "shi," which is a large region, formerly called a prefecture (and far larger than any western conception of a city). Within that region there are rural counties and urban counties (qu), the latter of which are roughly comparable to a metropolitan area. Within the urban qu is the area of continuous urban development, or the urban area. Prefectures ("shi" or city") virtually ALWAYS have large rural populations."

The error in the article comes from comparing the population of the city of Los Angeles (3.8 million) to the "city" of Changsha (7.0 million). But these are radically different concepts for which the same term (city or shi) is used. The city of Los Angeles is a municipality that represents less than one-third of the population of the Los Angeles metropolitan area or the Los Angeles urban area. The city of Changsha is a region that extends far beyond the metropolitan area or urban area of Changsha. Thus, when comparable geographical constructs are used, Los Angeles is four times the size of Changsha (metropolitan area or urban area).

Here are the data on comparable areas…

Changsha (2010 census based)

"Shi" or "city" (formerly called prefecture): 7.0 million

Metropolitan area (urban qu): 3.1 million

Urban area (continuous urbanization): 3.0 million

Central municipality: No comparable area

Los Angeles

"Shi" or "city" (formerly called prefecture): No comparable area

Metropolitan area (Los Angeles and Orange Counties): 12.8 million

Urban area (continuous urbanization): 12.2

Central municipality (City of Los Angeles): 3.8 million.

Now that was offtopic.. but very interesting. So I guess we can't take seriously any population comparisons between chinese and western cities.
