Musk’s Terafab projected to be larger than the Pentagon, Apple Park, Mall of America, and Giga Texas, combined — all-in-one chip manufacturing facility visualized to show the project’s massive footprint

Elon Musk's Terafab will have at least 100 million sq. ft of interior space, making it the largest such structure on Earth by a big margin. It seems that it will need this amount of space, though, for Musk's ambitious plan of bringing multiple semiconductor manufacturing processes under one roof.
