"Six vertical tubes would support the ramps and would provide vertical transport spaces for people, energy, waste, water and prefabricated modular steel elements for the skyscraper's growth."
Sounds like elevators to me.

Have fun identifying what level you are on, (gradient 6.5 NNW sector B)
Sell it as a skate park for the upwardly mobile...

Above four floors, people either would not get outside much or be in increasingly healthier shape as their residences neared the top.

If that is your sole takeaway after reading the article, you've missed the point. Elevators of some type will always be needed to move large, heavy furniture and supplies .and occasionally people.
The design isn't intended to eliminate elevators. It purpose is to essentially to create a single long, uninterrupted level as opposed to the multiple floors of conventional construction.
It is a unique design, but won't be practical for every application..

I agree, 'vertical transport spaces for people, ' does sound like elevators.
I assume if one uses the ramps, one would have to rest every so often getting to the top or be healthy to walk that far.
IMO, it looks like a stack of papers that have been cut into shapes.

It would take you an hour to reach the top floor! This is just ridiculous. How would you possibly maximize the space above the 10th floor. No one is going to walk up all that way. It's interesting, but it's NOT functional.

I'm with Bob Flint on this one "Sell it as a skate park for the upwardly mobile," but I would address more for the downwardly mobile. I reckon that by the time they hit the street, a skateboarder would be going some, though I think any speed record would probably be awarded posthumously.

Impressive looking but totally impractical. People who live in high rises may not take well to having strangers walking by their windows. It offers unlimited take off points for base jumpers and suicidal maniacs. All that 'shelving' will create unpredictable and risky situations with wind and rain. The bridges are too large and will significantly darken the light shaft for the lower floors. Residential buildings like this should be crowned with glass atria at the tops, instead of flat and boring surfaces of little use. Elevators to go up, yes, but taking the ramps to go down will take too long, and since these ramps occupy valuable real estate in the structure, they may become a sore point for the developers.
But it sure looks nice!

This is similar to the Horton Plaza shopping center in San Diego, with more levels & multiple rather than a single use. Drapes, blinds & windows set above eye level will protect privacy as they already do the world over. Creative guard rail design combined with video surveillance will make jumping from the ramps impractical. A retractable roof will be necessary, though, to keep the open area comfortable & to minimize energy consumption in cold & very hot weather.

How to build a skyscraper without a huge crane, all of the materials can be drove to there destination with relatively small equipment. Bravo ! Elevators can be added at any point in the build. As the cranes main support in traditional construction is used as the elevator shaft in some buildings. Now i'm no expert, but this seems like how the pyramids of Ancient Egypt might have been built. It falls under the KISS system of engineer/building or just doing things smart. And not needing a crane might save some cash on a build. Anyone know what a 100 story 50 ton crane costs ?
