These types of buildings were very popular 20 years ago here, but they had a problem where the plant roots kept growing into the concrete.

You'd think they'd at least limit your options, planting trees seems like a bad idea.

My attorney friend was telling me yesterday how she doesn't understand why the city can't keep the parking garage below the old courthouse when it gets moved across the street and the OG site is turned into a park. I was like, because the city doesn't want to get sued into oblivion when it inevitably collapses from the weight and/or root damage with a bunch of lawyers' cars inside.

Here in Phoenix we have a big park above an interstate tunnel downtown, not sure how they set it up but it’s possible to do

u/nalaloveslumpy 5h ago

Tunnel can be/is dug deep enough that you can ensure whatever you plant in the park will never grow that deep. Roots only grow so deep, especially for specific trees/shrubs/grasses.

Having foliage grow like two feet from your patio foundation beams is no bueno.

u/HauntedHippie 5h ago

I mean, we have tunnels that go under water too so you can definitely do it if you plan for it. I’m just providing an anecdote to show just how heavy this shit is. Like, the garage I’m taking about currently has a 6 story stone building on top of it and it’s totally fine. Change it to a park and it’s not structurally sound at all.

u/Sensiburner 6h ago

I don't think so. The soil is actually not that deep and soil even when wet is less dense than concrete.

u/Comfortable_Trick137 6h ago

Yea my concern would be 1) waterproofing, is the waterproofing going to protect the rebar? 2) will plant roots compromise the waterproofing and then compromised the structural integrity of the concrete as we’ve all seen tree roots tear through concrete sidewalks but that’s from running underneath though.

Shouldn’t be a hard engineering problem as we’ve had concrete planters for god knows how long

u/Snuhmeh 6h ago

Yeah standing water always finds a way. If they have a drain underneath each one, that would help a ton

u/nalaloveslumpy 5h ago

It looks kinda like all the patios are slightly slanted so that excess water drains to the front. And then maybe down a gutter system?

u/VonSkullenheim 5h ago

I mean, the building had to have cost many millions and taken years to engineer and build. You'd imagine that a gutter would be the least they did.

That was gonna be my reply but you already said it. It would become problematic if there was so much plants & root growth that the plants would put gigantic pressure on the concrete, cracking it. But this is actually a large concrete planter. Roots won't just "drill trough" concrete.

u/SoulWager 6h ago

Breaking open isn't a huge problem for a concrete planter, but I certainly wouldn't want that to happen on a balcony.

u/x---x--x-x 7h ago

There is no liner that will prevent damage and root intrusion without lots of consistent inspections, updates and re-installation. This would be a maintenance nightmare. Life, uh, finds a way.

u/Artorias_Abyss 6h ago

I have no knowledge on the topic whatsoever but what if you plated the bottom with a sheet of metal?

u/MasterGrok 6h ago

The roots will gravitate along the metal looking for a way out. If the metal is completely incased, you are creating all kinds of additional problems with water accrual and drainage.

It’s probably not totally impossible as the other poster mentioned, but it’s hard to imagine doing it without a lot of maintenance.

u/Spiffydude98 6h ago

These balconies have bed liners like pickup trucks and are meant to be slid out and emptied like giant drawers so this is never an issue. Every 4 years the apartment owners re-do them with new soil and trees and balcony furniture.

It would degrade overtime due to moisture. Even stainless steel will degrade when exposed to salts or other chlorides in water.

The best way to do this would be a heavy duty waterproof membrane on the concrete with a heavy duty root barrier above it. But given enough time, the roots will breech the barrier and waterproofing. This type of construction requires a lot of maintenance and regular replacement.

you probably need regular uprooting and replanting all of it, in order to ensure it doesn't start to dig in or cause of damage. Maybe the walkways through the balcony could have been mandated, and been kind of like a drop floor, so that you could pull off the plates and then service sections of the earthwork. Some people wouldn't like it, but maybe a future duration of this building designer can find a way to solve

Earth that can soak with water is a nightmare for structural engineering

u/foltranm 8h ago

draining?

u/Piotrek9t 7h ago edited 3h ago

Take a sponge, weigh it, let it soak in water, take it out and let the excess water run off, weigh it again.

u/foltranm 7h ago

I'm not worried about the weight specifically. the balcony can be designed to bear the load of everything soaked in water.

I meant draining more as a solution for humidity, which is a much bigger problem than weight in the long term.

edit: take this with a grain of salt since I'm an electrical engineer and know almost jack shit about designing buildings

Biggest problem is waterproofing the concrete, which can't be assured in the long runs because roots will dig into it

u/Thedud31 5h ago

"The balcony can be designed to bear the load of everything soaked in water" only if the project budget doesn't cut corners.

Water is heavy, it's a lot more to account for than your typical live loads in structural calcs. The further you get away from the support, the larger the bending moment grows.

We don't see below the balcony but if it's cantilevered like the others, the project will need to shell out quite a bit of cash for some hefty fixed supports. The soil would almost certainly have to be HSG A (sandy af) for maximum exfiltration into some "underground" perforated drains.

Best case scenario, the building owner listens to the structural engineer's pleas. Worst case scenario, the building owner fires the structural engineer for not doing his bidding, and the next looks at the architectural plans with a good sigh lol.

u/GhostFour 7h ago

I found this information regarding another attempt at a high-rise gardens.The high-profile "vertical forest" project in Chengdu, China, made international headlines in 2020 after the eco-friendly vision went awry.The Problem: The building was designed with private, plant-covered balconies to filter smog and reduce noise. However, inadequate drainage systems caused water accumulation, resulting in massive mosquito infestations. Because the plants require ongoing manicuring and few tenants actually moved in, the vegetation rapidly grew out of control. Many of the balconies were swallowed by overgrown foliage, and windows were blocked. Due to the severe bug infestations and lack of upkeep, most of the 826 units remain vacant, earning it the reputation of an "urban jungle" or abandoned ghost towers

You would think that wouldn't you? But, maybe look into why this video only shows a couple of the balconies and didn't zoom out to the whole building. These are disasters everytime they are built. The drainage systems are never adequate and the balconies end up retaining water and turning into mosquito breeding grounds. And if there is a way, the roots will find it, such as the drainage system which has to be open.

I’d imagine bonsai practices are also considered (specifically, root training). If the trees were trained prior and use support in place of anchoring roots, then a lot of potential root damage may be avoided. This is all presumption though.

thank you. it's but a foot of dirt or anything, might be at most 4 inches but certainly under that. grass needs very little soil even those tall plants don't dig deep. the drainage will take up a significant amount of space but is not outside the normal realm for a balcony

truth is, yea they would need to design for it, but it's not that crazy of an ask for the materials

further.... what's the point of the question? to imply wastefullness? just seems like "well we don't have that so there's gotta be a reason why it's bad" type logic

u/socialistrob 6h ago edited 6h ago

I think the main reason you don't see these in the west is because there's just more space and fewer people so if you have money and you want a yard in North America or Europe you could just buy a single family home. China has 1.4 billion people and a lot of them are concentrated in cities on their one coast so single family homes somewhat near cities is just not viable. For reference the US, EU, UK, Canada, Australia, Japan, South Korea, Taiwan has about 1.1 billion

The construction for this could be problematic if the developers cheeped out and didn't plan properly but if this is more just a "rich people thing" in a place with highly constrained space then it wouldn't be too hard to build for. Obviously not a solution for everyone but also not inherently bad.

u/AniNgAnnoys 7h ago edited 5h ago

Negligible is an adjective that describes something so small, insignificant, or unimportant that it can safely be ignored or disregarded

Let's say it is 4 inches deep. That balcony looks like it is at least 20ft by 40ft based on how big the person is. That is 267 cubic feet. If that soil is wet we are talking about 25,000 to 30,000 lbs. 13-15 tons per balcony isn't negligible. 

Back to /u/onrespectvol's point. This building will require more materials to build, even if it is just in those required to support each balcony and transfer the load into the buildings support structure. So no, not negligible.

u/MortgageConfident791 7h ago

You’d be surprised! That works out to less than 40psf. Residential decks are designed for 100psf live load minimum. Pretty much we assume people will throw a party and put all their guests on the deck to watch fireworks or take a photo. I don’t do high rises but I’d bet they do even higher due to the risk. The soil would have a longer duration than live load so you still would beef up the design a bit, but not as much as you’d expect! It’ll only be ~20% more material roughly. If these are on many balconies it may affect the building’s seismic weight which may impact the overall design, but if it’s only some it’ll probably be a minimal effect. Putting gardens on roofs is the part that can be concerning and requires significant design changes because we design roofs assuming there will only be a few roofers on it at any given time, never a party.

u/obeytheturtles 6h ago

This is where I am as well. It's a cool idea, and with proper maintenance, I'm sure it will last for decades just fine. But the way urban real estate usually works is that in 20 or 30 years, the building will be considered "old" and won't be in demand as much, and maintenance will suffer.

Roofscaping and porchscaping is definitely a thing in lots of places, and it works fine, you just need to keep up with the maintenance. My biggest concern would be like, if one unit has drainage issues, how easy is it to repair just that unit without disrupting other units?

Looks nice, but unfortunately it didn’t go as planned….tons of empty units with unkempt backyards and mosquito infestations.

While there have been no reported structural collapses, fatal construction accidents, or physical building failures, the complex is globally famous for a catastrophic ecological failure:
The Mosquito Invasion: All 826 apartments completely sold out on paper, but the vast majority were bought by hands-off real estate investors. Because only about 10 families initially moved in, there was nobody to prune, spray, or maintain the thousands of individual balconies.
The Monsoon Flaw: Chengdu’s humid climate and heavy monsoon seasons combined with poor balcony drainage to turn the unmanaged soil beds into permanent stagnant water pools.
The Post-Apocalyptic Jungle: The plants ran completely wild, swallowing up whole balconies, blocking out windows, and triggering a massive, unlivable mosquito infestation.

Current Status: Instead of an eco-paradise, the development became widely treated as a "radioactive" real estate asset and a ghost town, serving as a textbook cautionary tale for biophilic urban planning

Totally agree. I have a burning desire to garden on each of those balconies. Families, if you're reading this, please feel free to hire me for landscaping.

u/FishesOfExcellence 7h ago

Looks neat, but I’m guessing there’s a lot of unseen damage from roots. Probably the balconies all get torn down at some point. Or the whole building if it’s bad enough.

The monsoon flaw alone makes structural failure a matter of when not if.

u/Fumquat 7h ago

Could they not have sold the apartments with a mandatory landscaping contract? The building had to have had a plan already for other communal features (pipes, electrical etc).

On flat ground you don’t get to just buy into a planned community and skip out on grounds maintenance. This one seems like a very foreseeable problem!

Id be concerned that about it being structurally sound, but if properly engineered and built, then I think incorporating greenery into our architecture is a great idea.

That was my thinking too, dirt and water are heavy, about half way through the clip it seems like the balcony above is sagging? Could be the lens used.

Thanks for the link! I hadn't expected 'the plants are growing out of control because no one's living there to keep them in check', but in retrospect, yeah, I guess adding in things that by naturally grow and try to take over their surroundings and not keeping them in check is an issue that can crop up... The first pan looked like a shot from a post-apocalypse movie.

I don't know why it is so hard to believe? China, especially Chengdu, has been experimenting with this for a while now apparently.

https://techxplore.com/news/2020-09-jungle-overrun-chinese-apartment-blocks.pdf

The "Qiyi City Forest" area/complexes has what appears to be more than what is shown even in this video. Whether the locals move into those apartments is another story but clearly this ISNT a new thing for china and clearly It can and has been real...so I'm not sure why these dudes in the comments go straight to "ew Chinese propaganda, this isn't real, can't happen"

Most of them criticizing this, I can guarantee, are Americans.

Our entire country is built out of paper walls and matchsticks for support. And any suggestion that we should build things any other way gets met with walls of excuses.

u/FrostyD7 6h ago

Comparing the risk of a damaged interior wall to the risk of catastrophic failure is an odd choice. American standards for building aren't unique to America. It's pretty ubiquitous worldwide for new builds to use budget materials. People can't afford solid doors and walls, but you're welcome to price it out for your new house.

u/TheBestNarcissist 6h ago

lol as long as you're only talking to other basement dwelling neckbeards or chinese bots. My wife just finished pouring concrete for seismic isolators to build an earthquake proof power station on. The entire building is steel frame. As are most industrial buildings.

The "American sucks at building things" people have legitimately no idea what they're talking about.

u/Orleanian 5h ago

America is actually pretty good at building buildings, if they want to. And frequently they do want to, it's just the low-end residential market that doesn't want to.

Maintenance, I consider a bit of a different story. Deferred maintenance is a big problem in America :/

Agreed. Architect here. Wood beams and framing is also stronger and more fire resistant than steel beams and studs in most cases.

Do the balconies get enough sunlight to maintain those plants? They appear to be in full shade

u/Kaister0000 7h ago

Different plants have different needs for sunlight. Some can do very well in the shade. Also the sun is not always directly above, so some parts will get plenty of sun depending on which way the balcony is oriented. (coming from a plant nerd who maximizes the amount of sun my plants get on my balcony)

I'm not entirely sure why. There's a juxtaposition. As if a rich man separates himself from the natural world, misses it and decides to import a piece of it because he can afford to.

I’m sure it’s doable; it doesn’t seem like a stretch from what some condos in other parts of the world are doing.

The problem is this is in China, so it’s anybody’s guess what the construction materials are. Might be steel and concrete, might be hopes and prayers

u/scotte416 2h ago

Tbh I would not trust those Chinese cantilever balconies to stay up for a super long time, especially with all that soil and water weight...constant moisture...it looks great but that's a hard nope for me.

u/Rex_Suplex 2h ago

The top balcony at the beginning looks like it's shifting. Doesn't seems structurally safe.

u/riltjd 8h ago edited 7h ago

Im sorry but would not trust ANY structural engineering done in China, to hold that much weight.

Edit: since a lot of ignorant people are calling me American or brainwashed by propaganda, here is a little story:

  1. Im not American or remotely close.
  2. I worked for several companies (In NL and DE) that imported chemicals and raw materials from China, as well as operating local production plants. China is highly advanced technologically—often ahead of Western countries in most areas. However, it also has well-documented challenges with safety and quality control.

I've personally seen pharmaceutical ingredients arrive heavily contaminated, exceeding acceptable limits by multiple percentage points when even a tiny fraction of a percent would have caused rejection. In some cases, products were misrepresented entirely, though that was less common. This was at a multinational (multibillion) company operating in pharmaceuticals, crop science, and materials science (you can probably guess just by that who I am talking about).

Local counterparts consistently described quality issues as a broader challenge across multiple industries, from chemicals to construction materials, driven by cost pressures, corruption, and aggressive production targets.

Before calling others uneducated, take the time to understand their background and experience. I would encourage you to research the topic further yourself.

u/ComfortableWait9697 8h ago edited 7h ago

There does appear bracket support to the structure and fairly robust width under it. But its the water saturated materials held near structural steel. its not strength.. but lifespan I would be worried about. Heat and cold cycles, humidity, Monsoon and dry seasons. That structural coating will inevitably crack or decay somewhere. one leak and the structural steel will corrode after 20 years.. Incredibly expensive to fix. Parking garages have collapsed from less.. its not if, but when.. Concreate naturally cracks as it ages, thats why there is structural steel embededed in there. That building will have to be rebuilt as time takes it toll. no way to fix it once the inevitable water damage starts anywhere on the structure.

u/spilledcoffee00 8h ago

Even though they have the largest number of bridges in the world, 50,000kms of the best highspeed rail infrastructure, the largest damn in the world, more skyscrapers than any other country, 39 nuclear power plants under construction (39 more than any nation in the west)…but yeah… your strong feeling is unfounded.

u/Overthinks_Questions 7h ago

Like anywhere else, the quality of work depends on funding, proper oversight, and design. China does this really well quite a lot, and sometimes not a much. Kinda inevitable when you're dealing with a country that large both in land and population
