My palms are sweating as I write this post, because even the thought of someone free soloing a skyscraper makes me clammy. (Free solo means climbing with no ropes.) But that's what climber Alex Honnold is scheduled to do live, on Netflix, on January 23, 2026, at 8 PM ET.
He will be climbing Taipei 101, which is over 500 meters tall, one of the tallest buildings in the world, and formerly the world's tallest. Dubai's Burj Khalifa stole this superlative in 2009 when it was completed.
My palms continue to sweat, but Alex is of the opinion that, as far as enormous towers go, this one is relatively safe for free soloing:
Honnold said the shape of the building makes it safer to climb because there are balconies every eight floors. “You could actually fall in tons of places and not actually die, which makes it safer than a lot of rock climbing objectives,” he said.
I can see the logic.
The architecture of Taipei 101 consists of inverted trapezoids that are stacked on top of each other. Each is 8 storeys tall and they angle outward as you move up, creating a roof condition or terrace on top of each module.
Eight is an important number in Chinese culture because of a homophone in Mandarin; the number sounds like "to prosper" or "to make a fortune." So that's why the modules are the height that they are.
It is now also dawning on me that the nested modules of One Delisle are 8 storeys tall. That's good! This was never talked about during the design phase, but now that I'm aware of it, I'm going to pretend it was deliberate.
I guess this also means that One Delisle would be a relatively safe building to free solo climb. Please, nobody try this.
Good luck, Alex.
I came across this tweet the other night showing Toronto's Yonge Street.
In the foreground are small, two-storey main street—type buildings. And behind them are tall buildings. This is very Toronto. What you're seeing here is a condition that occurs all around the city. Though in many ways, it feels counterintuitive. I mean, shouldn't the tallest buildings be right on the main street?
In my opinion, this condition is happening for at least two reasons.
The first is that Toronto's historic main streets tend to have a fine-grained lot fabric, which means they're more challenging to assemble for larger developments. Assemblies are a complex art, and they get exponentially more difficult the more property owners and feuding siblings you add into the mix. So the path of least resistant is larger and chunkier sites.
The second reason has to do with context. We tend to want to preserve the feel of our historic main streets. One Delisle is an example of this. The podium of the tower is scaled to exactly match what was there before — an Art Deco-style facade from the 20s that will return to the site.
However, we didn't have this same constraint on its other elevation (Delisle Avenue) and so we fought not to have your typical podium + setback tower. Instead, we wanted a street level experience that had more presence and urban grandeur.
This, to me, is an important distinction to consider. Are we setting height back because of history and context? Both of which are important. Or are we setting it back because we're pretending to still be a provincial Anglo-Protestant town? Sometimes it seems like it's because of the latter.

This week the team submitted a rezoning application for the southwest corner of Yonge & St. Clair (1 St. Clair Avenue West).
More of the details can be found over here on Urban Toronto, but so far the response has been overwhelmingly positive. People seem to appreciate the architecture, the public realm improvements, as well as how we're proposing to deal with the embodied carbon in the existing building.

The application proposes to retain the existing 12-storey office building and both expand its floorplates to the west and build new residential on top. In the middle is a shared multi-storey amenity space that also performs some pretty cool structural gymnastics courtesy of Stephenson Engineering (see above rendering).
This approach created some interesting design challenges for the team. Typically when you're adding onto an existing building, you want to do something new and not try and copy/bastardize what's already there. Oftentimes this means something more contemporary.
The architecture team at Gensler Toronto tried this approach but the podium proportions didn't feel quite right when we did it. So a decision was made to instead pay homage to the existing building's architecture, and then kind of reinterpret it by playing with scale and other details.
This way the original building remains architecturally legible, but the entire podium still reads as one and its proportions feel much better. We hope you like it as much as we do.
