I'm pretty impressed that it's possible to build that high on a wood frame. I was guessing there was a steel frame inside.

With cross-laminated timber you can go even higher (though I imagine it's more expensive than this building style): https://en.wikipedia.org/wiki/Cross-laminated_timber https://en.wikipedia.org/wiki/Cross-laminated_timber > In 2012, Forte Living, an apartment complex in Melbourne, Australia, became the tallest plyscraper framed with CLT alone. The building has 10 stories and stands just over 32 m tall. The 759 CLT panels necessary for the project were manufactured in Austria using European spruce that was grown and harvested there.[31]

    Yes, though that building does use some concrete and steel: https://matadornetwork.com/read/wood-hotel-sweden/ https://matadornetwork.com/read/wood-hotel-sweden/ > The hotel’s not without any metal, though. Generators and heating/cooling units on the fifth and sixth floors are supported by a steel truss. There’s also concrete atop the hotel to minimize sway. But for the most part, the Wood Hotel is a marvel of white wood and forest aromas, like living in a life-sized doll house designed for the 2020s. Obviously much, much less than a typical tall building though.

Fire safety, not the strength of wood framing, is what blocked this type of construction before. Effective sprinkler systems are what addressed that concern. There remains a concern about fire safety during construction, before the sprinklers are activated. There have been serious fires and deaths of construction workers while these buildings were going up.

The Ascent MKE is a mass timber example completed in 2022. From Wikipedia: > The 284-foot (87 meter), 25-story high-rise is the world's tallest mass timber structure, edging out Norway's Mjøstårnet. It features 259 luxury apartments, retail space, an elevated pool with operable window walls, and a sky-deck. https://en.wikipedia.org/wiki/Ascent_MKE https://en.wikipedia.org/wiki/Ascent_MKE https://ascentmke.com/ https://ascentmke.com/

  I'm still a bit fuzzy on the actual structure of these buildings. Based on descriptions in Wiki and elsewhere mentioning "cutting out holes for windows and doors" it makes it seem like the structure is not just the usual steel frame but with wood beams instead of steel, but there are instead perhaps full wall surfaces made of CLT which would participate in load bearing which I can see adding a lot more strength.
