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.
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.
Does a factory count? If so… https://en.m.wikipedia.org/wiki/Boeing_Everett_Factory
The NASA Vehicle Assembly Building is also a contender.
I’m not sure how many dividing walls there are inside Everett, but the VAB is basically one massive empty skyscraper.

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

Thats crazy! Fascinating! Could one engineer a climate system such that it always rained? Can lightning and thunder occur as well?
