Tesla and SpaceX plan to construct Terafab, a gargantuan semiconductor production complex in Grimes County, Texas. When fully completed, the facility is projected to span over 100 million square feet, a footprint that would dwarf every current structure on the planet. Terafab Will Be the Largest Building on EarthTo put Terafab’s proposed footprint into context, it easily surpasses the current world record holder, the New Century Global Center in Chengdu, China, which covers roughly 18.9 million square feet. Compare this to:The Pentagon (6.6 million square feet)Mall of America (5.6 million square feet)Apple Park (2.82 million square feet)Terafab's Sci-Fi City DesignWhether the structure ultimately secures the global record will depend on whether construction follows the proposed scope. Economic FootprintThe project is anticipated to generate at least 3,000 primary positions, targeting job seekers from Grimes County and neighboring Brazos County.
