A skyscraper complex may consist of multiple skyscrapers, as well as other buildings or facilities, that are either physically connected to each other or part of the same development project. To qualify for these lists, skyscrapers must be constructed close to each other and be part of a single complex. Significant height differences between the buildings are allowed as long as they belong to the same project. Buildings may or may not be connected via a podium or skybridges. Non-skyscraper buildings or structures can be part of the complex, and their floor area may be included in the total calculation. Single-skyscraper complexes typically include a skyscraper integrated with a shopping mall or other facilities. The lists below are categorized based on the number of skyscrapers within a complex. One skyscraper This list includes complexes that feature only one skyscraper, providing an alternative measurement for some skyscrapers already listed in the Largest skyscrapers in the world section above. To be included, these complexes must have a total floor area of approximately or more.
