Frank Lloyd Wright originally proposed The Mile-High Illinois in the 1950s. Innovations in construction materials and elevators are necessary to reach the one mile height and beyond. We may see the first mile-high skyscraper by the middle of the 21st century.
The undefeated champion of the skies right now is the Burj Khalifa in Dubai, which stands at 2,717 feet (roughly half a mile) and is the tallest building in the world.
Although take that with a grain of dusty salt—only 1,916 feet of the Burj Dubai is occupiable space, the rest is vanity height, meaning nearly 800 feet is non-occupiable space. That represents 29 percent of the building's
There are three major construction and stability aspects that must be dealt with if we're to reach a vertical mile. Those are:
Dampening wind sway
Elevator speed and length
Construction materials

“And the transit time getting to your floor. Thousands of people all going home about the same time? Impossible.”
Put condos every few floors.
“Stairways”?
How about “escape pods”? It might save weight.
Hugo first!
Likely it would be a multiuse building
Office space, living space, garden levels, shopping sections, food sections/restaurants
“the fountains of water in the land of Shinar. And they built it: Forty and three years were they building it...”
I think that is near me in Chicago!
Now called the Monadnock Building!
About as high practical with brick/masonry.
The bearing walls at street level are about eight feet thick!
As you look in from the street you first might think they are displays made to look like this?

Geronimo Lines.
1. A tall (16?)brick one in Chicago massive eight feet thick walls. Things have improved...

2. Even a typical high rise has draft stops and some pressure adjustment from the HVAC blowers.
3. Usually, a curtain wall exterior moderates the temperature and is independent of the structure.
A cool video on building the St Louis Arch.
The two columns did not align for the keystone because of sun/temp differentials.
They had the fire department hose one side for proper alignment.
For black iron ~ 1 inch for 100 degrees F , for 100 feet.
Add a skosh for stainless like the Arch.
That said they have it covered, I think?
That’s the real question. Why is being on that particular block so important to that many people as to justify the cost?
Not sure but nano tube tech might work for the structural system. A new solar collecting glazing product could help with power generation. Even wind turbines could help with power. A water harvesting system could be integrated within the building skin material with collection channels. ....
This would be a fun project to work on. Kinda like designing colonies for the moon.
If you read Arthur C Clarke’s 3001, it has a hug skyscraper in it (four, I think, but everything happens in the one).
People living in the upper floors rarely leave. It’s a city unto itself.
Also, in Clarke’s case, those people really couldn’t leave because of the low gravity the were living in. It was a really big tower.
What happens when the electricity goes out (or, in the event of a ‘Green New Deal’ the wind stops blowing/Sun stops shining?)
I already have issues when the elevator breaks down in my 4-story building and I’m coming home with a prepper-load of groceries; and I’ve seen videos about buildings that are so tall that the people have to call down to the front desk many mornings, to find out what the ‘weather’ is like - they live in clouds.
Give me Terra Firma, thanks...
Also there is no reason that the elevator cars to be placed in a shaft, why can they not travel up the sides of the building on special rails?
Typically elevators are in the building core.
Having them next to a shear wall is handy, also they have lots of delicate electronic components
Moisture and elevators a bad combo.
At Cabrini–Green Chicago the elevators were appended to the exterior wall; nothing but problems.
on the Observation Deck you can actually see the main damper, which has what is basically a giant plumb bob in it. You can actually see the building’s sway.
Way cool!!!
Piker. You could make a 2 mile high sky scraper in Leadville!
Plumbing would be a hassle.
It is done in stages, an approx half a pound of pressure per foot of elevation.
5280/2= 2640 PSI, a bit too much for your drinking fountain!
Also, the waste pipes make a 90-degree offset every so often, to prevent noise... would not want the pipes to crack if something solid was flushed.
Put condos every few floors.
A common proposal for mega buildings.
I have noticed that the monkeys acquire strange habits after some time in the zoo.
And then the next wave of the virus...
Hanging from a crane, they used to do that around the US, a few years back.
Yes... Just build half of it... Underground...
Somewhere in the US, they built a library, not a mega building, but with about ten floors below grade???
In reality why would you?
The same reason guys gotta have faster cars...
Bragging rights.
Oh look at me, my shite hole country just spent 5% and counting of our GDP on the tallest building ever!!!
But the curtain wall insulation might have some minor fire issues; enjoy it while you can.
The current figure for elevators runs at 1,600 feet as wire suspension ropes cannot support their own weight and any additional weight after that point. Aside from the technical limitations, needing multiple elevator lobbies would take up too much valuable space. A few years ago, Finnish elevator company Kone developed a carbon fiber cable, UltraRope that they believe could double the distance of an elevator rope. This would be enough to get those would-be mile-high penthouse residents to their sky digs.
Still in development.
