The Tesla Gigafactory outside Sparks, Nevada could take the cake in a handful of years, though. The final size is unknown, but current planned floor space is 13.6 million square feet, 71 feet tall, and 5.5 million square feet wide. As designed, it’d be second in volume to the Boeing building, but purchase of the adjacent property gives them the option to expand and Tesla has hinted at doubling the factory pending earnings and feasibility. Elon Musk: taking over the world(s).
