Current Tallest Building in the World and Its Record Height
The tallest building in the world is the Burj Khalifa in Dubai, United Arab Emirates, which officially holds the record for the tallest structure and tallest building in the world. The tower reaches a structural height of 828 meters, or 2,717 feet, with 163 occupied floors and a total floor area of more than 300,000 square meters. The project was developed by Emaar Properties, designed by Skidmore, Owings & Merrill, and opened in January 2010, and it remains the definitive benchmark for supertall building height worldwide Forbes.
The Burj Khalifa's height is measured to its architectural top, which includes its spire, and it dominates the Dubai skyline while also serving as a mixed-use center for residential, commercial, and hospitality space. Its height record is measured by the Council on Tall Buildings and Urban Habitat, which tracks the tallest completed buildings globally and confirms that no other completed building has surpassed its 828-meter mark as of the latest available data Council on Tall Buildings and Urban Habitat.
Why Burj Khalifa Still Holds the Record and What Comes Next
The Burj Khalifa still holds the record because no completed building has yet reached a height of 828 meters, despite multiple projects in Saudi Arabia, China, and the United States that aim to exceed it. The Jeddah Tower in Saudi Arabia, developed by Kingdom Holdings, is designed to surpass 1,000 meters, but as of the latest public updates, it remains under construction and has not yet been completed or officially measured Forbes.
Engineering challenges such as wind loads, concrete pumping, elevator systems, and structural stability at extreme heights make surpassing the Burj Khalifa's record a complex and costly undertaking that requires advances in materials and construction methods. Developers must also secure financing, regulatory approvals, and tenant commitments for supertall towers, and the economic viability of buildings above 800 meters depends on high-value mixed-use programs and strong demand for premium office and residential space Council on Tall Buildings and Urban Habitat.
Key Engineering and Construction Facts About the Tallest Building
The Burj Khalifa used a reinforced concrete core and buttressed foundation system to manage lateral forces, and its construction involved high-strength concrete pumped to record heights and a cladding system designed for extreme desert temperatures. The tower's Y-shaped floor plan and tapering silhouette help reduce wind vortex shedding, and its foundation relies on a massive mat supported by deep piles driven into the underlying rock Forbes.
Construction of the Burj Khalifa began in 2004 and was completed in 2010, with Samsung C&T Corporation serving as the main contractor and Bill Baker of Skidmore, Ow
