In the last decade, there’s been a movement towards using wood to build skyscrapers via cross laminated timber construction. Why is that? The biggest reasons behind this are environmental factors and structural integrity of wood. Plus, thanks to advancements in building cross laminated timber, it's become sturdier and more fire resistant and a high quality material to build. Even though it's more expensive than steel and concrete, it could be a great option for developers and leads to much quicker building times because wood construction allows for much more prefabrication. As population increases and urbanization is the future of building cities, wood buildings could be a game changer and lead to a future of wooden skyscrapers. What are your thoughts?

It's very important to note that this is engineered wood product, not 100% lumber from tree. There is significant usage of glues and epoxies as binders. These binders and adhesives have their own issues in scaling up production. It is not accurate to state it is just trees which is the source material whereas a lot of additional binders are needed. The cost and environmental impact of these binders needs to be taken into consideration.
I'm all for it, if you can engineer around the traditional issues with tall wood structures:
Fire, termites and other insects, wood rot and sway
How tasty would termites find these buildings? I'm sure that carpenter bees would appreciate such luxurious digs, too.
Yeah
Wood cutter ants would be regular tenants of these structures as well
Just 8 videos on the whole channel, cant believe the great quality of these videos. You and your team are going places
Thank you so much! I appreciate you watching
My city, Edmonton, builds apartments out of wood that are four floors high. I’d be nervous about anything higher than that.
Bc it would burn down
No multifamily building over 3 stories should be made of wood or composite material. All it takes is a fire between the ceilings and floors to disable the fire sprinkler system. Personally I believe concrete reinforced steel structures are the absolute best and safest ways to build a home and or a skyscraper. Of course places like New York, steel framed buildings are ok but in south Florida only steel reinforced concrete is the norm.
The wood used in these building are resistant to fire. It's not the same type used in standard housing.
Loving the channel, you're growing fast and deserve it. I see a lot of folk have already mentioned the comparisons to B1M and that's a compliment! Also, I love checking the comments to see how many people ask questions that have already been answered in the video 🤣
LOL so true about the questions from video. And thank you for watching all the way through and commenting!
I think Insulated concrete forms are the future, for Walls and floors 👍👍
My concern is about water, mold and rotting. Especially in low-lying coastal communities, I don't exactly trust the wood to hold up.
Since wood is a permeable fiber structure, it can be impregnated with all sorts of resins or glues to waterproof it. These would also often be included to enhance its structural properties anyway. Just think of it as naturally-occuring carbon fiber
@@brickmack But what happens when those cements wear down? Because they are going to be worn out at some point.
@@shanekeenaNYC Then you demolish the building and make a new one. That won't happen for decades
@@shanekeenaNYC the same question can be asked for redular steel and concrete buildings. It takes decades to wear out if done right, and at the end of their lifetime, you have to demolish and rebuild. (Also, who knows if we have some new outlandish recycling tech when that time comes)
*EXACTLY!* its weird how people who are "environmentally" friendly PUSH wooden skyscrapers when that takes MORE trees to be cut down... like NAH concrete is the way to go. Ancient Greek buildings are still standing today thanks to their version of concrete! *THATS* sustainable!
You're my new favorite channel! Keep it up I LOVE every single video!!
Its definitively giving the B1M a run for its money
Thank you!!
Hahah I'm glad to hear that. I love B1m
7:19 It's actually called the Mjøs Tower. Because it's in the lake named Mjøsa. Tårnet is the Norwegian translation of tower.
Good video, however, I have some thoughts: (1) Skyscrapers are usually defined as being at least 100m or 150m tall, none of the finished buildings are this tall and therefore should be referred to as high rises instead. (2) If you need subsidies to build these, I don't think they will ever become that popular. Governments don't have the money to subsidize that many buildings and people are obviously preferring concrete buildings (for whatever reason), otherwise, no subsidies would be needed to encourage their construction. (3) Scandinavia, Austria or Wisconsin have lots of trees. The vast majority of people, however, live in places with minimal timber availability (China, India, Middle East). Those places will never see wooden buildings.
Yes, it kinda seems like yet another government boondoggle in the name of “climate change.” It’s now impossible, at least for me, to make heads or tails of what’s legitimate and what’s propaganda. Weird time we live in.
Just imagine the damage one crazy person could do within their own apartment, potentially burning down the entire building and everyone above them....
Won't happen if constructed properly.
Fire risk?
Can you make a video about Chicago please because Chicago started the skyscraper and has some of the most beautiful iconic skyscrapers with a Skyline that is unmatched
Yes, are you talking about 1 Chicago?
Thanks for the video. I've seen a few other similar videos but it's always nice seeing different ones to get multiple perspectives. I think your video would honestly get more views if the thumbnail and title were more indicative of the topic being wood as a possible future for skyscraper construction. For example, check out the thumbnail and title for PBS News Hour videos - "Is mass timber the building material of the future" or cheddar's "wood skyscrapers are on the rise - cheddar explains".
Thanks for your feedback, I appreciate you taking the time. I'm gonna take this into account and split test the thumbnail to see if I can get one more evocative
One of the points your missing on also if you want to speak on carbon storage is that with the warming polar regions (warming faster than the equatorial regions) methane is being released into the atmosphere and scientist have stated that the arctic used to be grass land and grassland keeps methang in the ground better than trees because they cover all the ground and continually grow, ad scientist have said by returning the polar regions to grasslands would make for a healthier planet. there are probably 100'sof millions of not over a billion trees in the Taiga and by cutting most of them down if they can be converted to grassland at the same time there would be more than enough wood to build countless structures from wood while also helping our planet thrive. And with the opening of these places to the lumber industry there can be stipulations that they have to fix the coutles spaces they destroyed around teh world from strippping whole areas of all their trees, so they would be dong double good by replanting billions of tress in areas that should be forest and then cutting down billions to turn land that was once grasslands back into grasslands.
Fantastic storyline, keep this great work up. Am waiting for your new feeds and perspective. Ty
Thank you Mori! I appreciate you watching my videos :)
I live in the Fort Lauderdale/Miami area of Florida. My concern would be flooding and wind damage from hurricanes. Also, our ever increasing heat
That's a very valid point
Damn, we're actually all here early. Only 7k subs so far. This content is A1. Keep it going!
Thanks for your support!!
You should cover Boston's new seaport area. New neighborhood and extremely expensive. Fits your content. I live in this city so if you need local insight or Broll footage I got you. Love your channel. Subscribed ❤️
So funny you say that, I have it planned for one of the next videos to post. I went to undergrad at NEU and think seaport is a super interesting neighborhood
London should build the Oak Wood Tower!!!!!!!!
What about earthquake resistance? Is it stronger than concrete with rebar?
A lot of the wood buildings still have concrete & rebar in the foundation and core so they're not 100% timber, and I think the structural stability and safety is a big reason why concrete is still used over wood for certain parts of the construction
How safe are wood buildings in earthquake areas?
That’s a good question
Cool video!
Thank u!
Yes, wood has stored CO2 inside which does not get emmitted when when wood is used as building material, but at the same time the cut-down trees cannot absorb CO2 from the atmosphere anymore. So, in times where forests are declining but desperately needed to absorb CO2 and slow down global warming, it does not look like a good idea to cut them down for construction and prevent them from working as "air filters".
Did you watch all the way to the section where deforestation is discussed to address that issue?
In the place of the cut down tree, you plant new one. Trees absorb CO2 when they grow.
Ever heard of the forestry industry? (Not the logging industry, its 2 different things)
@@urbaninternational it still doesn’t make it sustainable. I need the tree more than I need the building. Wood skyscrapers are a gimmick. I’d rather breathe. People think that because you slap sustainable before the practice that it nullifies the inevitable consequence that it has on the environment. These arguments for wood skyscraper proliferation are argued, I think, on the basis of preference rather than anything legitimate in terms of practicality (to balance the needs of the environment and human settlement).
I get it. You (and so many other architects) no longer find traditional building materials and architecture stimulating. You want something new… like how Art Deco was new in the early 1900’s. However, this is not the way to do it. It’s time to put the art back in architecture. More critical thought is needed. Wood construction for a global population of over 8 billion is grossly unsustainable and dangerous. I want to breathe.
@@alienamzal477 how long does it take to grow a new tree the same size as the one you cut down?
@@chaostheory16 so you didnt understand what I said. A Mature tree stores more Carbon, but its rate of absorption of CO2 is much lower than a new tree that is still growing. When you cut down the mature tree and take it to construction, the Carbon stored doesnt go anywhere, it still remains in the wood as Carbon. And it frees up the space for a new tree that will absorb more CO2 as it grows and stores it, then it goes down for construction and a new tree takes its place. This goes in a cycle in a forestry plantation.
(Iam not talking about just clearing out natural forest, which have this cycle occur naturally. Iam talking about plantations of trees and harvesting them for wood in cycles like you would do for any other crop)
Architects been playing minecraft
True
Very good video. Thanks
Thanks for watching!
Great video.. well done✓
The real matatan.🤔.oh wow
Ribirin.
Thank you
So we won't have any forest left 😕.
I don’t think you watched the full video
Better start growing forests
Europe sure is already!
Just my personal opinion, but I don't like the aesthetics of a tall wooden building. They tend to look clunky.
That's fair
Um, didn’t we move away from using wood because entire cities were burning down? 🥴
But now we have engineered wood and hybrid products that didn't exist in the past
theres a reason why we use steel
Ten Billion Earthlings Is Likely
Indeed
I really don't think that's sustainable at all regarding deforestation. Unless we would be talking about wood recycling.
The deforestation remark was meant in regard to countries that have strong re-forestation policy. In others, it's absolutely a big concern with illegal logging and deforestation.
carpenter ants? termites?
Lunch time for them
yeah yeah wooden towers would be so cool
🖥🦫
hahaha the emojis
WEVE COME FULL CIRCLE !
@@Valentien23 LOL
🔥Why Skyscrapers Should not be Made of Wood🔥
LOL
*NOT VERY WISE - - what happens if there's a FIRE in a wooden skyscraper???*
Did you not watch up to the point where fire hazards with CLT is discussed in this video?
@@urbaninternational no - just watched the first few minutes - - BUT - - i don't see how u could possibly get around that. If u are aware of all the fires that broke out in NYC before building codes were invented - - its very easy to see how fast disasters can emerge when you're dealing w/wood - - ESPECIALLY on the scale of a skyscraper - - its just nuts - - the entire building could collapse within hours. Cheers.
@@_Breakdown You should consider watching the video. This concern is addressed and dismissed.
@@twmcmahan I’m not sure I’d say the issue is “dismissed.” How much testing has this really undergone?
Any building built out of wood is *beyond stupid* , it's just better to live in a tree than to live in a building made out of wood. 😂
Hahaha how many people here just want more B1M content lol
Hahaha idk if that's a good thing or bad thing, but B1m is a channel I definitely take inspiration from
@@urbaninternational Definitely a good thing! You make great content for your size.
@@TheNoerdy Thank you
Would you sell your channel?
I'd sell anything for the right price
0:07 different times I guess
I'm not sure what you mean by that
@@urbaninternational construction worker balancing on a steel beam without any safety measures
Ah yes, very different safety standards these days for sure!
Please send me mansion for sale now!!!
Mansion?? I'll take one too while you're at it
*SORRY* but no thanks... Stick to concrete. Just look at Ancient Greek buildings that are still standing today.. Thanks to their version of concrete.
CO2 is necessary.
Very necessary indeed for some things
I bet after 75 years, they’ll transition to stone skyscrapers
What if we just came full circle and went back to concrete skyscrapers but poured the entire building out of concrete not just the foundation
@@urbaninternational like 3D printing out of concrete? That would be an interesting topic for another video. I remember seeing one about a 2 storey house that was 3D printed out of a Cement like solution, cant remember the channel I saw it in
Bro…. Not for a skyscraper lol for buildings up to 10 floors bt thats it
