This list of largest buildings in the world ranks buildings from around the world by usable space (volume) and floor space (area). The term "building" used by this list refers to single structures that are suitable for continuous human occupancy. There are a few exceptions which include factories and warehouses.

Boeing's factory in Everett, Washington, United States is presently the largest building in the world by volume while Terminal 3 of Dubai International Airport is the largest building in terms of total floor area. The surface area of the proposed Crystal Island complex in Moscow is more than double that of the largest current building, though this project has been delayed indefinitely by the global economic crisis.

Largest usable space

This list ranks the buildings throughout the world with the largest amount of usable space.

• Boeing's Everett Factory is currently the world's largest, used to assemble a selection of the company's largest aircraft, originally built for construction of the 747. This building is 13.3 million m³ (472 million cu ft) and covers 398,000 m² (98.3 acres) of land.
• The Aerium was built to house the construction of a giant airship, although the airship was never completed. This building now houses an indoor, artificial tropical resort.
• NASA's 160 m tall Vehicle Assembly Building was originally built to enable simultaneous assembly and shelter for four Saturn V rockets.
