“Because green skyscrapers and high-rises are a bullshit non-solution to serious systemic problems.”
“But if you want greenery on a building nonetheless, do I have an idea for you – a portable, modular, scalable solution called ‘potted plants on your balcony’.”
Water is heavy, and plants are made of mostly water.
Ok. Is water heavier than steel ? I think most buildings can support a bunch of plants
The issue I was trying (and failing) to get at is the additional weight the building now has to support on top of everything else a building normally has to support. However, it doesn’t seem to be a big deal judging by everyone’s replies.

The blueprints https://bauarchivddr.bbr-server.de/bauarchivddr/archiv/dokumente/3-4-01-2-wohnungsbauserie-wbs-70-6-3-t.pdf
This is the blueprints of a pre modern apartment building (its in German but you could use chat pdf if you need translation) more modern buildings use these as basis (modified versions of course) as these block buildings are modular, cheap, very resistant and reliable. They can definitely support the extra weight of some plants on the facade, nobody wants to plant trees on the building, that wouldn’t necessarily be a weight problem but rather a problem with the roots damaging the building, and you can’t really stop tree roots, maybe some smaller trees but definitely not Oaks or Fruit trees.
That’s awesome, thanks for the info!
No problem
I have no idea. Not an architectural engineer.
My assumption would be that they have to build the building to a code that has a minimum weight requirements.
Male Humans are generally averaging about 80kg.
If you have a party and have 10 - 15 over. That’s a lot of weight. Not all the time but I think if every apartment had a few plants then the weight would still be less than having a party.
Or that was my assumption anyway. I know balconies have a weight limit, as there was a story about a party and too many people were out on it and it collapsed
Depends on the plants…
Also… Humans are mostly water as well if you go by that. I know my balcony supports 3,2 (+ the required tolerance) metric Tons of weight on a area of 10 square meters.
I could plant a tree there. Probably more than one. And these building concepts are rather about small plants, so the weight shouldn’t be a problem if you build with Reinforced Concrete like a normal person.
Except that plants grow… and grow, and grow. Unless they’re maintained, which takes additional labor and people and infrastructure to handle, all of which adds even more weight.
As said, you don’t need to use trees or gigantic plants, use Twiners and shrubs, they cover the whole facade and don’t way that much, yet they do the same, if not a better job at keeping the building cool and the air cleaner. They don’t need much maintenance and they don’t grow indefinitely, if the plant cant reach more facade it stops, only thing is you have to regularly cut the plants around the windows, wich isn’t a gigantic problem.
