A mushROOM!
Armillaria ostoyae fungus, also known as the honey fungus, is the world largest organism and covers over 2300 acres!
thanks dad
Anytime, champ!
Does a factory count? If so… https://en.m.wikipedia.org/wiki/Boeing_Everett_Factory
Factories will win this hands down, especially when you’re building large/complex items. It looks like the distinction might be “single building” vs “complex or buildings”, but VW’s Wolfsburg plant is 70 million square feet. The largest plant I’ve been to isn’t on that list, but it’s still over a half mile wide - all under a single roof.
I went looking but couldn’t find a reference. US Air Force Plant 4 in Fort Worth (where the F-35 is assembled) was at one point the longest length building without internal support columns. I’ve been told that there is a twin building somewhere else, but the one in Texas is 25 feet longer. I just can’t find a source with the number!
Boeing Everett Factory

Volume: 13.3 million m³
That being said, I don’t know if it is internally divided.
There’s a really large cave in Southeast Asia somewhere.

The Sơn Đoòng cave in Vietnam:
Formed in Carboniferous/Permian limestone, the main Sơn Đoòng cave passage is the largest known cave passage in the world by volume – 3.84×10⁷ m³ (1.36×10⁹ cu ft), according to BCRA expedition leader Howard Limbert. It is more than 5 kilometres (3.1 mi) long, 200 metres (660 ft) high and 150 metres (490 ft) wide.
So that’d be nearly triple the volume of the Everett Factory. Though the cave has two holes in its roof, and I don’t know exactly how you define “room” here.
They had to change their venting and airflow system for that building after it formed a cloud and rained inside. When your room can have weather systems, I feel you’ve entered a whole new category of ‘room’ by definition.
Thats crazy! Fascinating! Could one engineer a climate system such that it always rained? Can lightning and thunder occur as well?
You could say the Veryovkina Cave in Georgia is the biggest room in the world, if you define a room as a single continuous enclosure not impeded by any barriers or gates. It’s referred to as the Mount Everest of caves and has six points of entry once thought to be unrelated. My best friends are cave hobbyists (my body isn’t ready as they say, though to be fair neither are theirs for different reasons), seeing/capturing never before things all the time, and are probably evading the law that far below our overworld right now.
I’m not sure of the volume of that system, how to get it. But I wonder if man made strip mines like these would compare:
They go on for miles, are huge, and theoretically could go on for basically forever.
Impressively not even close. The Veryovkina Cave is the deepest cave but the largest is the Hang Son Doong cave in Vietnam and that’s just under ten kilometers. Again a place shown to not be immune to my friends.
Makes me wish I could be into that stuff, might be interesting to see the life and art down there.
What’s the single biggest constructed room? By humans, inside a building.
LOL the link in that post goes to a crypto scam.
Probably The Asylum.
Admittedly, The Asylum has a quite a few rooms within it, but I’d say that the antechamber of The Asylum that abuts the outer wall to Outside comprises the majority of the surface of the Earth and its atmosphere, so that’s a pretty big room.
Yer mum’s rectum!
Nah I don’t know
That’s a hallway, not a room.
A hallway is a kind of room.
The oldest room in the house, in fact
Would the super kamioka in Japan count?
The inside of the asylum from hhgtg
Interesting question. Are we talking about the volume or the floor area? For volume maybe a church? Then St. Peter’s Basilica in Vatican City would be the largest. I don’t know the layout though, but I assume a large portion of it is the main “room”.
Or do stadium with a roof count? Then maybe one of these?
Edit: I don’t think I really thought this through. I was thinking too much of more roomy rooms. Most convention centers probably have larger exhibition halls.
Probably volume altho i suppose I’m probably taking it for granted that a volumetrically massive room would also have massive floor space
Stadium with a roof doesnt count
