Completions by Country Note: Only countries with at least two completions in 2015 are included in this chart. One tall building 200 m+ in height was also completed during 2015 in these countries: Australia, Azerbaijan, Bahrain, Canada, France, India, Italy, North Korea, Philippines, Saudi Arabia, Turkey, Vietnam. For the eighth year running, China had the most 200-meter-plus completions with 62, representing 58% of the global 2015 total, but only marking a 2% increase over its previous record of 61 in 2014. Indonesia took second place with nine completions, and the United Arab Emirates followed closely with seven. Meanwhile, Russia came in fourth with five completions and South Korea trailed with three.

Completions by City Note: Only cities with at least two completions in 2015 are included in this chart. One tall building 200 m+ in height was also completed during 2015 in these cities: Baku, Guiyang, Haikou, Hangzhou, Ho Chi Minh City, Izmir, Jeddah, Jiangyin, Jinan, Kunming, Lanzhou, Liuzhou, Lyon, Manama, Mandaluyong, Melbourne, Mexico City, Milan, Monterrey, Mumbai, Ningbo, Pyongyang, Seoul, Shanghai, Surabaya, Java, Taiyuan, Tangerang, Toronto, Wuhan, Wuhu, Wuxi, Yekaterinburg Jakarta, Indonesia had the highest 200-meter-plus completions of any city in 2015 with seven, while Nanjing, Nanning, and Shenzhen tied for second place with five each. The total height of the buildings completed in Jakarta is 1,588 meters.

Completions Timeline The 106 buildings completed in 2015 beat every previous year on record, including the previous record high of 99 completions in 2014. This brings the total number of 200-meter-plus buildings in the world to 1,041, exceeding 1,000 for the first time in history and marking a 393% increase from the year 2000, when only 265 existed. A total of 13 supertalls (buildings of 300 meters or higher) were completed in 2015, the highest annual total on record. Since 2010, the number of supertalls in the world has exactly doubled, from 50 at the end of 2010 to 100 at the end of 2015. We currently project the completion of between 110 and 135 buildings of 200 meters' height or greater. Perhaps even more staggering is the fact that 18 to 27 of these buildings are expected to be in the supertall range. If true, 2016 alone would see the global total of supertalls increase by 18% to 27%. Unsurprisingly perhaps, the majority of these will be located in Asia and the Middle East.

Completions by Location Once again, Asia was a major driver of skyscraper completions in 2015, with 81 buildings representing 76% of the 106-building total. The Middle East had nine completions in 2015, marking the first time since 2009 that the region had less than 10 200-meter-plus entries in a year. Europe had a big year with eight completions, an annual record for the region, while Central America makes a notable appearance on the list with four.

Completions by Function In 2015, the functional split for tall building completions appears to have remained relatively unchanged from 2014. That being said, all-office completions have hit another all-time record, with 52 buildings (49% of the total). Mixed-use buildings have also achieved impressive numbers, with 30 (28% of the total). In terms of all-residential completions, there were 20 in 2015 – two more than in 2014, representing the same percentage of the total (19%) as last year.

Completions by Material In an interesting turn of events, 2015 saw a spike in the number of buildings completed with concrete structures – 52 out of 106 (49%). This is a dramatic increase over 2014, when only 39 out of 99 were completed (39% of total). Indeed, greater showings from Europe and Central America were the cause of this anomaly, as these regions have a greater tendency to build tall using this material. Equally interesting is the fact that 46 of the 48 composite completions were in Asia, where material availability, seismic requirements, and workforce specializations are such that composite solutions are often the most desirable. Compare this to Europe and Central America, where concrete is often preferred due to its widespread availability and low cost when compared to steel. All-steel towers were very scarce in 2015, with only three 200-meter-plus completions around the globe. One of these is J57, a tower in Changsha, China that was built by Broad Sustainable Building (BSB) in only 19 days thanks to a CTBUH Innovation Award-winning modular construction technique that the company hopes to employ on a 202-story building known as Sky City.

Skyline: Tallest Building by Year

At 632 meters, <a href='https://skyscrapercenter.com/building/shanghai-tower/56' target='_blank'>Shanghai Tower</a> was the tallest building to complete in 2015 and is now the world’s second-tallest building.

Average Building Height Although the average height of all 200m+ completions seems to fluctuate each year, the average height of the tallest 100 buildings continues to rise as the industry pushes itself further into the sky.

World's 100 Tallest by Location

World's 100 Tallest by Function

World's 100 Tallest by Material All-steel continued its decline as a primary structural material, comprising only 3% of 2015’s 200-meter-plus completions and 11% of the world’s 100 tallest buildings.

Total # of 200m+ Buildings The number of 200-meter-plus buildings in existence has hit 1040, a 392% increase from 2000.

Buildings Entering 100 Tallest The number of buildings entering the World’s 100 Tallest list has remained relatively static over the past four years, with 13 entering the list in 2015, 13 in 2014, 12 in 2013, and 13 in 2012. But this year is particularly noteworthy because it is the first year where every building in the list is a supertall (300 meters or higher). With 18 to 27 supertalls projected to complete in 2016, it might not be long before we surpass the 2011 record of 18.
