What is the largest building in the world?

The largest building in the world, according to Guinness Book of World Records , is Boeing's Everett Plant, located in Everett in Washington, USA. The famous passenger aircraft, 747, 767 and 777 are collected. Since then, it has expanded twice, 45 percent in 1980 for the 767 assembly line and another 50 percent in 1993 for 777 assembly. The total footprint is 1,025 hectares (415 hectares), with 282 hectares (113 hectares) of buildings and 215 hectares (86 hectares) for reinforced yards and parking. As a result, the largest area in the world is equivalent to a little over a square kilometer. For example, Aerium in Brandenburg, Germany, about half the size of Everett, was originally built as an assembly area for Giana airship that has never been built. The NASA vehicle assembly building in Florida is about a third of the size of the Everett plant as it was builtto build shuttles.

There are several buildings slightly larger than the Everett plant, but in general it does not get credit, because not all their floor space is usable. For example, the Aalsmeer Flower, Aalmeer, the Netherlands, is slightly larger, but not all its floor spaces are usable and evaluated lower than the Everett plant. It is still qualified as the largest building in the world for commercial (unlike industrial) use and a long shot is the largest building in the world dedicated to flower auctions.

China's Great Dam and China Three Gorges are two other structures that challenge the Everett plant for the world's largest building. The Great Wall of China is over 6,500 km long, but does not qualify like building because it has no interior and small real usable space. Similarly, the Three Gorges dam does not qualify as a building in itself, because the overwhelming inIts interior is not usable in fashion, which usually means a "building".
