The year 2019 marked a defining moment in vertical construction as the Council on Tall Buildings and Urban Habitat (CTBUH) documented a record-breaking number of supertall building completions worldwide. A total of 26 supertall buildings measuring 300 meters or above were completed, surpassing the previous record of 18 set in 2018. For those fascinated by vertical engineering, examining the Tallest Skyscrapers World list reveals just how dramatically the skyline shifted in a single year. While supertall completions soared, overall completions of buildings over 200 meters declined slightly, signaling an important shift in the construction industry toward pushing absolute height boundaries rather than simply building many moderately tall structures.
The Surge of Supertall Buildings Worldwide
The supertall category, defined as buildings reaching 300 meters or higher, experienced an unprecedented boom in 2019. The 26 completions represented a 44 percent increase over the previous record and brought the total number of supertall buildings in existence worldwide to 170. To put this in perspective, the world had only 26 supertall buildings in the year 2000, meaning the count has grown more than sixfold in less than two decades. This rapid acceleration in height records has been accompanied by new material innovations, including the rise of mass timber in high-rise applications. The concept of Plywood Skyscrapers How Mass Timber Is Reshaping High Rise Construction demonstrates that even the tallest structures are beginning to explore sustainable alternatives to traditional steel and concrete frameworks.
The geographic distribution of supertall completions was heavily skewed toward Asia. China alone accounted for 14 of the 26 supertall buildings completed in 2019, reinforcing its position as the dominant force in global high-rise construction. Several Chinese cities including Tianjin, Suzhou, and Wuhan each added supertall towers to their skylines, with many of these buildings ranking among the tallest in the world.
Regional Contributions to Skyscraper Growth
Beyond the supertall segment, the broader tall building market covering structures of 200 meters or more saw 126 completions worldwide in 2019. While this figure represented a decline of 13.7 percent from the 146 completions recorded in 2018, it still reflected a robust global appetite for high-rise construction. Understanding where these trends are heading requires looking at The Future Of Skyscrapers Four Engineering Marvels To Look Out For, which highlights upcoming projects that promise to redefine the upper limits of building height and design.
The regional breakdown reveals interesting patterns in tall building completions:
- China led the world with 57 tall building completions in 2019, though this was a significant drop from 92 completions in 2018. The deceleration reflects China’s tightening regulations on skyscraper construction and a shift toward quality over quantity in urban development.
- The United States held second place with 14 completions, up slightly from 13 in 2018. New York City dominated the American market with 8 buildings of 200 meters or taller completed during the year.
- The Middle East contributed 11 completions, down from 13 in 2018. The United Arab Emirates accounted for 9 of those, with most concentrated in Dubai and Abu Dhabi.
- South Korea added to its growing skyline with multiple completions, including the LCT The Sharp Landmark Tower in Busan, which ranked among the top 10 tallest buildings finished in 2019.
Within the United States, New York City was the only city to complete supertall buildings in 2019, adding four such structures to its skyline. Miami contributed three tall buildings, while Chicago, Boston, and Austin each added one. The concentration of supertall construction in a single American city underscores how few markets globally have the economic density to support buildings exceeding 300 meters.
The 10 Tallest Skyscrapers Completed in 2019
Among the 126 tall buildings completed during the year, ten stand out for their exceptional height and architectural ambition. Each of these structures pushed the limits of construction technology and design. The rise of horizontal connections between tall structures is another fascinating trend, explored in depth through Skywalk Engineering The Rise Of Horizontal Skyscrapers In Modern Construction, which shows how engineers are linking towers to create multi-building megastructures. The tallest buildings completed in 2019 are listed below:
| Rank | Building Name | Location | Height (feet) |
|---|---|---|---|
| 1 | Tianjin CTF Finance Centre | Tianjin, China | 1,739 |
| 2 | Lakhta Center | St. Petersburg, Russia | 1,516 |
| 3 | Suzhou IFS | Suzhou, China | 1,476 |
| 4 | The Exchange 106 | Kuala Lumpur, Malaysia | 1,460 |
| 5 | Wuhan Center Tower | Wuhan, China | 1,437 |
| 6 | LCT The Sharp Landmark Tower | Busan, South Korea | 1,350 |
| 7 | 30 Hudson Yards | New York City, United States | 1,270 |
| 8 | Dalian International Trade Center | Dalian, China | 1,214 |
| 9 | Golden Eagle Tiandi Tower A | Nanjing, China | 1,208 |
| T-10 | Raffles City Chongqing T3N | Chongqing, China | 1,163 |
| T-10 | Raffles City Chongqing T4N | Chongqing, China | 1,163 |
The Tianjin CTF Finance Centre claimed the top spot as the tallest building completed in 2019, soaring to 1,739 feet. This mixed-use tower in northern China features office space, a hotel, and luxury residences. The Lakhta Center in St. Petersburg became the tallest building in Europe upon completion, marking a significant achievement for Russian construction. The presence of two Raffles City Chongqing towers tied for tenth place illustrates a broader trend of building pairs or clusters rather than isolated towers.
Key Engineering Factors Behind Record Heights
Achieving heights above 300 meters requires sophisticated engineering solutions that go far beyond simply stacking more floors. Several critical factors enabled the record number of supertall completions in 2019:
- High-strength concrete and steel alloys allowed columns and cores to support greater loads without increasing cross-sectional dimensions. Modern concrete mixes achieve compressive strengths exceeding 80 megapascals, enabling thinner walls and more usable floor space.
- Advanced damping systems became standard in supertall towers. Tuned mass dampers, viscous fluid dampers, and outrigger trusses work together to counteract wind-induced sway that would otherwise make occupants uncomfortable at upper floors.
- Digital modeling and Building Information Modeling (BIM) allowed project teams to coordinate the complex systems of supertall buildings with unprecedented precision. Clash detection, structural analysis, and construction sequencing were all optimized in virtual environments before breaking ground.
- Modular construction techniques accelerated supertall project timelines. Prefabricated facade panels, mechanical equipment skids, and modular bathroom pods reduced on-site labor requirements and improved quality control.
The engineering demands of supertall buildings also drove innovation in foundation design. Deep pile foundations extending more than 100 meters into the ground became common for the tallest towers, with some projects requiring continuous around-the-clock concrete pours lasting multiple days to create monolithic mat foundations capable of distributing enormous column loads.
What 2020 Projected for Skyscraper Construction
The CTBUH projected that between 115 and 145 buildings of 200 meters or taller would complete in 2020, a slightly narrower range than the 120 to 150 projected the previous year. This conservative estimate reflected growing uncertainty in global construction markets and tightening regulations in key markets like China. In the United States, New York City was expected to deliver 10 tall buildings in 2020, headlined by the 1,550-foot Central Park Tower and the 1,428-foot 111 West 57th Street building. These two supertall residential towers were poised to further transform the Manhattan skyline, though their completion timelines ultimately faced delays unrelated to engineering challenges.
The 2019 construction data offers several important lessons for the industry:
- Supertall construction is becoming more common. The record 26 completions in 2019 suggest that the technical barriers to building above 300 meters have been substantially reduced through accumulated expertise and improved construction methods.
- Market concentration remains high. China and the United States together accounted for more than half of all tall building completions globally, with China alone responsible for 45 percent. This concentration indicates that the economic prerequisites for tall building construction limit the market to a relatively small number of urban centers.
- Height records are shifting eastward. Of the ten tallest buildings completed in 2019, eight were in Asia. This geographic shift reflects the rapid urbanization and economic growth of Asian cities, particularly in China.
- Sustainability concerns are growing. The exploration of alternative building materials and energy-efficient designs for supertall structures signals a maturing industry that must balance height ambitions with environmental responsibility.
The record-breaking year of 2019 demonstrated that the era of supertall construction is not only continuing but accelerating. With advances in materials science, structural engineering, and construction management, the next decade promises even taller and more ambitious structures that will continue to reshape skylines around the world.
