New York of of China. But Shanghai didn’t have enough space. On the other side of the river was industrial and rice patties area that was rather barren, very marshy. The urban design that had developed basically was to transform Puang into an international office center.
And the result of that was the inclusion of of 80 office towers, the lowest of which was 40 stories in height. Of the 80 towers, three towers were to dominate. three were to be super towers. In the early 90s, construction began on the Jin Mau building, the first of these super tools. The Oriental Pearl TV Tower also topped off.
This was the world that William Pedison entered. It was a Shanghai on the verge of becoming the city as we know it today. But it wasn’t quite there yet. Well, I’m I’m a biker. I’ I’ve been a biker for 50 years and the Shanghai was a city of bicycles. It was so serene just that quiet hum in the morning. The justosition between that hum and what one experiences now is so profound.
Pettison is the P in KPF, a major American architecture studio. Like many Americans at this time, he looks to Asia for work. We’ve worked extensively in Korea, extensively in Japan, and extensively in China. Pedison was working with Japanese real estate tycoon Manora Mori, one of the most powerful developers in the world, thanks to his family’s business.
And he was negotiating with the city during all of that time, but once he had completed those negotiations, uh, we started our work. This relationship was fruitful on both sides. Pedison needed work and Mory needed skyscraper experts. The Jim Mau building rising just across the road from where Pedison was to build his own skyscraper gave an idea of what a Chinese super tall could look like.
The building was designed by Adrien Smith, another American architect in Shanghai and it was modeled off Chinese pagodas. But Pison wanted his tower to be different. Architecture at this time was moving away from the postmodernism of the 80s and into a style we would now call neofuturism. Postmodernism was all about referencing other styles in a playful way.
It was a reaction against the minimalism that came about in the midentury. It was eclectic and loud. Neofuturism, it could be said, was itself a reaction against postmodernism. This style was more about seamless dynamic forms, clean lines, and smooth surfaces. It was optimistic and looked to the future. At the drawing board, Pedison broke down the concept of a skyscraper into its basic fundamentals.
What does a skyscraper essentially do? It’s there in the name. It connects us to the sky. uh one was an earth symbol which is essentially a square prism and the other was a symbol of the sky, the symbol of heaven and it was a circular disc sort of a flattened doughut shape with a central hole in the middle of it and the juxiposition between those two represented a juosition that we could illustrate architecturally in terms of lightness versus weight.
Pettison put these two forms together, the square prism that represents Earth and the disc that represents the heavens, and that gave him the shape for his skyscraper. A circle seemed like the obvious solution. It was aesthetically pleasing and referenced not only the ancient Chinese symbol for the heavens, but the moon gate as well, a common architectural element in Chinese gardens.
Now, the void at the top also served another function. It would trick the wind and allow it to pass through the skyscraper, making the building more stable during strong storms. The building has a very specific orientation uh to the Oriental Pro TV tower. The upper floors are exactly perpendicular to the axis of it was intended to be the negative of a circle really was by all accounts perfect.
The plans were submitted in 1993 and the review process was a little unusual. Now, getting the facts straight is really important to me, especially when it comes to grappling with the history of such an influential skyscraper. I need to know everything, the good, the bad, and the controversially circular. These days, it’s pretty easy to get caught up in just hearing one side of the story, which is why I like using straight arrow news.
What many people don’t realize is that the typical news algorithms don’t always give us the full story. Half the time you can read two articles on the same topic, but come away with two completely different understandings of the situation. Whereas on Straight Arrow News, I know I’m just getting the facts, so I can then make up my own mind. There’s no spin here. It’s just clarity.
One of the standout things of Straight Arrow News for me and my pretty much favorite feature is the media miss tool which shows you which stories are being under reportported by different sides of the political spectrum so you can make sure you’re definitely getting the full picture.

Okay, time to head back to Shanghai. Once the plans for the building were submitted, it began a review process. 14 professors of architecture were given just 30 minutes each to respond to the design. They would give their responses in Chinese. These responses would be translated into Japanese for my then finally translated into English for Pettison.
Well, I’ll never forget that meeting. It was I had shown this building to everybody and everybody loved it, you know. So the first the first woman that began the critique, she’s a lovely appearing woman, elderly, very sort of motherly figure, and she got up and she said, “Well, perhaps this building is acceptable, but it certainly isn’t desirable.
” And with that act of foreshadowing and a refusal to elaborate any further, the building was approved. The piles for the foundations were driven into the ground and in 1995 it was full steam ahead. Then came 1997 and Asia had its own financial crisis. Skyscrapers are always a response to the economy.
China and all of these other places were taking off, but they then also suffered their own recession after 1997. So the paper tiger that was roaring began to recede and there was a hiatus in construction that lasted until the early 2000s that affected the Shanghai World Financial Center. When work finally resumed towards the end of 2001, the world was very different.
The Patronis Towers had completed and taken the crown of the world’s tallest building. Work on the next tallest building, Taipei 101, had also started. The race for the tallest was no longer between the east and west but now firmly in Asia and another world event had also made skyscrapers more important symbols.
Of course the resumption of work on Shanghai World Financial Center came after 2001 that is 911 and the enormous tragedy of the destruction of the World Trade Center Tower and the the loss of those lives. And one thought um for months after that event that there would be no more skyscrapers.
That was widely predicted around the world. Uh but meanwhile the uh global march or ascent of skyscrapers continued and there was um practically no pause. Skyscrapers were still a necessity for any major city and the tragedy couldn’t stop their construction, but the public was paying even closer attention to them. Now 911 changed the entire building code in China and the introduction of refuge floors which we still don’t have here in America.
Other changes came to the Shanghai World Financial Center 2. It was to be even taller, 32 m taller than originally intended. There was just one problem. The foundations had been laid to support the original height, not this new, higher and wider building. The design of the structure was based on the bearing capacity of the piles that had been driven. Yet, Mr.
Boy wanted to increase the lateral width of the tower and he wanted to increase the height of the tower by 40 m. The engineer who was um entrusted with the the new design was less Robertson who was the structural engineer for the World Trade Center. uh and Les Robertson who was uh you know a dear friend and a brilliant engineer came up with a solution that was able to answer the um the grief of the client.
The height and width of the building could be extended but it would mean decreasing the overall weight of the skyscraper by 10% so they could still use the existing foundations. Now to reduce the building’s weight the structural system holding it up was rethought. Robertson replaced it with a diagonal braced frame with added outrigger trusses.
The strength of these frames allowed them to reduce the thickness of the concrete walls in the core. This is where the building’s lifts, stairwells, and utilities normally sit. They could also then decrease the weight of the structural steel in the perimeter walls. Now, this actually worked out pretty well for everybody.
It made the construction process cheaper and faster. While Pedison was able to incorporate the outrigger trusses into the overall design of the building, the new structural elements also meant there were less columns inside the building footprint, allowing for uninterrupted and unparalleled views of Shanghai.
With this, work continued, but the city was keeping close watch. Soon, Pison and his team had to contend with one more pretty big problem. Public outrage. newspaper column was written. Japanese developer marches into Shanghai with a flag held high. You know, okay, we never even thought of it those tourists, but you know, cultural sensitivity is a very extraordinary thing.
The Chinese public turned against the tower. They saw the circular void as a Japanese flag planted on the Shanghai skyline by a Japanese developer. It was only a few decades ago that the Japanese had occupied Shanghai and much of China during World War II. Mr. called me, wanted me to come over for a morning meeting to Tokyo with the deputy mayor of Shanghai. And we had this meeting.
He explained, deputy mayor explained that this was an anniversary of the end of the Second World War. There, you know, this great sensitivity in in China at the time. So, could you please do something? Pedison tried at first to save his design by adding a bridge that would disrupt the circle and make it look less like a Japanese flag.
But that wasn’t enough to appease the Chinese public. You know, the internet really started to take hold at that time and the momentum just was too great. And so, we were asked to to reshape the form of the building and uh I can certainly understand why. These buildings are so symbolic. If the symbol isn’t isn’t right for the people that you know that that isn’t we’re not doing our job.
New plans were submitted in 2005 making the circle a square. In every skyscraper there always are conflicting factors of business and imagery and narrative and promotion just as important to confusing the wind and the various engineering values. that open space also had an economic rationale by making the number of of floor heights for the hotel that was in the top had an expanded uh footprint itself.
So there were there were many reasons that came together in order to make that a logical solution. The building finished at long last in 2008. It eclipsed the patronis towers but could not beat the spire that had topped Taipei 101, the new tallest building in the world that had completed in 2004. It was still the tallest building in the world by roof height and by occupiable floor, but not by overall height.
Probably could have designed two spires that going out from both edges of the building and going up that that’s probably what we would have done had we been asked. Mr. Moy was very much interested in having an elegant building. I the world issue of the world’s tallest building really what never really was talked about very much. I don’t know, maybe he anticipated that it would be a very temporary objective.
Even if the moniker of the world’s tallest building was incidental to the plans of the developer in the end, the tight race for the title in the late ‘9s and through the early 2000s shows just how massive the boom in skyscraper construction really was. A city capable of building such a structure is rare, and to have several at once competing is even rarer.

It meant this time saw incredible leaps in engineering and economic resources. But Mory was right. Holding the title would be a temporary one. Just a year later, the Burj Khalifa would complete with its incredible 244 m spire topping it off, making it far and away the world’s tallest building. Shanghai continued to grow. It’s now home to 24 million people and 194 skyscrapers.
It’s a far cry from the city that Pedison first visited in the early 1990s. Shanghai Tower now rises even higher next to both the Jim Mau building and the financial center. Together, these three structures form the world’s first adjacent grouping of three super tall skyscrapers. The Shanghai Tower was built taller than ours and and somewhat a deviation from the original intention.
But uh that’s that’s how it goes. Mr. Moore was no nonsense. He he built a fishing building. The Shanghai Tower has a lot of space that is really of questionable use. I think this building was probably designed more to be a showpiece, but I I I can’t I can’t criticize it past that point. The Chinese government has since introduced a ban on skyscrapers.
Smaller cities are now limited to a height of 250 m, though they can build higher than that in special circumstances. Larger cities are limited to a height of 500 m, but again, only in special circumstances. The moment China could have had the world’s tallest building has passed, at least for now. The Shanghai World Financial Center sits on the skyline as an iconic addition.
It’s been embraced by the people of the city and is even nicknamed the bottle opener because of its shape. They aren’t exactly complimentary names necessarily, but they they connect the buildings to the people in in that sense. It’s really good. People enjoy it, then I enjoy it, too.
I I hope it’s legacy is that which we intended to connect it through time. I I hope people will see and understand why it was designed as it is designed. I’m very pleased you’re you’re interested in in this building because it’s been a favorite great favorite of mine. This video was sponsored by Straight Arrow News.
