The Guardian recently published an article on vanity height in skyscrapers. What this is referring to is the unoccupied portions of tall buildings which are built purely for vanity reasons – that is, to increase the face height of the building and claim some superlative title.
Example:
The tallest building in the world is currently the Burj Khalifa in Dubai. It’s 828m tall. To put that into perspective, the CN Tower in Toronto is 553m. But according to the Council on Tall Buildings and Urban Habitat, 29% of the Burj Khalifa’s height is actually unoccupied or “vanity space.” In other buildings, such as the Burj al Arab (also in Dubai), the amount of unusable space is as high as 39%.
For the purists out there, this of course raises the question of what should should be counted when assessing building height. Should it only be spaces where humans typically inhabit? The CN Tower has a lot of unoccupied space, which is why it is frequently excluded from these sorts of ego rankings.
But semantics aside, this is obviously not a new phenomenon and it’s interesting to think about this race to the sky as a proxy for what’s going on in the world. Below is a chart showing which regions have been able to lay claim to the “tallest building of the year” since 1900.
Since 1990, it has been all about Asia and Oceania and China and Taiwan…
When I was in undergrad, I spent a summer in Taipei. One of the things I remember about that summer was how difficult it was to locate building addresses. Sure, there was the whole language barrier thing, but I swear that some of those alleys (which I loved) didn’t follow a consistent numerical logic.
Tall buildings will sway in the wind. And when they get taller and skinnier, the swaying becomes more pronounced.
In seismically active cities, such as Tokyo and Taipei, “tuned mass dampeners” are often used near the top of tall buildings to offset the swaying caused by an earthquake.
But tuned mass dampeners are also found in cities like New York, so that developers can build even taller and skinnier.
Below is a diagram from the New York Times showing what one looks like and how it works. The example tower is 111 West 57th Street.

A company out of the UK called what3words is trying to solve this problem. What they have done is created a 3m x 3m grid of the entire world and assigned a 3 word address to each square. Apparently that translates into about 57 trillion squares.
This is similar to long / lat coordinates, except that 3 words are far more user friendly than a string of numbers. They are more easily remembered and more easily communicated to other people. The front door of the Starbucks in my neighborhood looks to be migrate.stunner.racing.
One service that has built upon the what3words platform is a bike taxi service in Delhi that offers female drivers for female customers. It’s called Bikxie Pink and the 3 word addresses aim to solve the safety problem of inefficient pick-ups and drop-offs.
Even in places where addressing isn’t generally a problem, I could see what3words helping. Interesting platform.

Basically the masses are tuned to oscillate at a different frequency than the rest of the tower. So when the wind blows and the tower is moving one way, the weights are moving in the opposite direction and forcing the tower back towards some sort of equilibrium.
Neat. Structures was one of my favorite classes in architecture school.
