In 2018, 143 buildings of 200 meters’ height or greater were completed. This is a slight decrease from 2017’s record-breaking total of 147, and it
brings the total number of 200-meter-plus buildings in the world to 1,478, marking an increase of 141 percent from 2010, and 464 percent from
2000, when only 262 existed. Asia continued to be the most dominant region in terms of skyscraper construction, and China within it, as in several

The Middle East region is hosting its first CTBUH International Conference since 2008. In that year, there
were 119 completed buildings of 150 meters or greater height. Ten years later, there are now 387 such
buildings either completed or topped out (with expected 2018 completion), meaning an average of nearly
27 were constructed each year in the region during that decade. As this study will show, however, the
growth is not evenly distributed nor especially correlated to overall population, or to density. The dynamics,
and the reasons for high-rise construction in the region, are as diverse as the nations that comprise it.

Although the world has more than 1,300 buildings of 200 meters or higher, no tall building of more than 187 meters has been demolished, with the exception of the World Trade Center attacks on Sept. 11, 2001. However, JP Morgan Chase Bank plans to demolish the former Union Carbide Building (1961) in New York to make way for a taller headquarters building. At 215.5 meters, this would become the tallest building in history to have been peacefully demolished. This report examines the 100 tallest buildings in history to have been dismantled by their owners, and some of the reasons for doing so.

In 2017, 144 buildings of 200 meters’ height or greater were completed. This is the fourth record-breaking year in a row, and it brings the total number of 200-meter-plus buildings in the world to 1,319, marking an increase of 12.3% from 2016, and a 402% increase from 2000, when only 263 existed. Asia continued to be the most dominant region in terms of skyscraper construction, and China within it, as in several years previously.

Australia is one of the world’s least densely-populated countries, and yet it has one of the highest proportions of urban dwellers, a figure that is increasing. A boom in tall building construction is underway, paralleled by several significant transportation projects, particularly in the three CTBUH 2017 Conference cities of Sydney, Melbourne and Brisbane. This study examines the timeline, composition, and location of buildings 100 meters and taller (complete or under construction), set against the backdrop of new public transportation projects that are “connecting the city” and aligning towards a denser, more sustainable future.

As part of a recent collaboration with the Guinness Book of World Records, CTBUH certified that Shanghai Tower has the fastest elevator and the longest elevator run of all commercial buildings in the world. Expanding upon this study, CTBUH sought to determine the records for speed and length of run among the world’s tall buildings.

In the past few years, the tall building industry has become increasingly interested in the use of timber as a major structural element in skyscrapers. This has resulted in a now-worldwide wave of research, built projects, and ever more daring speculative proposals using “mass timber” – engineered wood products that are just as robust as their concrete and steel counterparts. This study examines recently completed and under construction timber structure buildings as well as a wave of new proposals.

CTBUH has determined that 128 buildings of 200 meters’ height or greater were completed around the world in 2016 – setting a new record for annual tall building completions and marking the third consecutive record-breaking year.

In this study, CTBUH undertook an examination of the populations, areas, densities, and several measures of skyscraper activity in the world’s 45 “megacities” – defined as urban agglomerations with a total population of 10 million people or greater, consisting of a continuous built-up area that encompasses one or more city centers and suburban areas, economically and functionally linked to those centers. The findings, also shown in the accompanying paper in this Journal: Megacities: Setting the Scene (page 30), are sometimes counterintuitive. While the world’s megacities have the majority of 200 meter-plus skyscrapers, there is not an obvious correlation between population density and number of skyscrapers. Vertical urbanism, it would seem, looks quite different in local contexts.

CTBUH defines a “twisting” building as one that progressively rotates its floor plates or its façade as it gains height. Usually, but not always, each plate is shaped similarly in plan and is turned on a shared axis a consistent number of degrees from the floor below. A stunning variety of textures, view angles, and ripple effects results from these manipulations, making these “twisters” some of the world’s most iconic buildings – and in many cases, aerodynamic and energy-efficient. In this study, we rank the world’s 28 tallest twisting towers (either completed or currently under construction) and display selected variations on the theme.

A timeline of skyscraper completions in New York uncannily resembles the boom and bust cycles of the United States in the 20th and early 21st centuries. The most active year was 1931, when the final excesses of the Roaring ‘20s were thrown skywards and frozen in concrete and steel. The scarcity of building materials clearly had their effects in the fl at World War II period. The rise of multinational corporations may explain the relative surge in skyscraper construction in the 1970s, even as New York City itself endured its darkest financial hours. Then come the wild “Wall Street” years of the 1980s, followed by the lagged effect of the early 1990s slump. The singular event of 9/11 did not have nearly the dampening effect on skyscraper construction, compared to the financial crisis of 2008-9. The current boom demonstrates New York’s persistence as a magnet for capital, and it’s standing as the ultimate skyscraper laboratory over time.

Perhaps no element of a tall building is more closely related to the pure pleasure of standing high in the sky and taking in the view of one’s surroundings than observation decks. Often adding an important source of revenue for the structures that have them, observation decks also change the way people view cities, and can potentially elevate their international reputation.

Japan is one of the world’s most densely populated nations, at an average of 339 people per square kilometer. It is also one of the world’s most active seismic zones. The combination of these factors has driven sophisticated design and engineering innovations that responded to Japan’s uniquely challenging conditions, including in the tall building field, which continue to this day.

Without big dreams, there would be no tall buildings. Conceiving, financing, designing, and constructing a skyscraper is no simple feat, even under the best of conditions. Many projects have had torturously slow gestation periods; many more have failed to start or were interrupted and cancelled. Naturally, we began to wonder how many tall buildings were started and not finished, and which held the records for longest construction time. Rumors of resurrections persist, and today’s long shot is tomorrow’s sure thing…

With the recent completion of two megatall telecommunication/observation towers it is perhaps time to review these structures and also explain why they are distinguished from buildings in the Council’s official tallest lists.
CTBUH Journal, 2012 Issue I
The annual story is becoming a familiar one: 2007, 2008, 2009, 2010, and now 2011 have each sequentially broke the record for the most 200 meter or higher buildings completed in a given year. Once again, more 200 m+ buildings were completed in 2011 than in any year previous.
CTBUH Journal, 2011 Issue IV
As of the year 2000, there were only 9 buildings 150 meters or taller in all of South Korea. Just twelve years later, there are now 124 buildings 150+ meters in height completed, with another 13 scheduled to complete by the end of this year.

New York’s dramatic skyline, over a century in the making, has for years been the envy of cities around the world. From the very birth of the tall building typology, New York has been at the forefront of the scene. Even as recently as the 1970s, New York City alone contained over 50% of the world’s 150 m+ buildings.

In a year dominated by news coverage of the new “World’s Tallest Building” – Burj Khalifa, Dubai – one may be surprised to learn that, besides being the year in which a building first surpassed the 600, 700, and 800-meter thresholds, 2010 has seen the completion of more skyscrapers than any previous year in history.
CTBUH Journal, 2010 Issue IV
Includes records of the tallest buildings/structures according to function and structural material, the highest spaces according to function, and some lesser-known titles such as the world’s tallest timber building, tallest religious buildings, highest swimming pool, etc.
CTBUH Journal, 2010 Issue III
Includes comparative studies of high-rise construction costs based on location and building function. Key high-rise cost drivers = shape & geometry, size & regularity of floor plate, structural solution, façade specification, environmental strategy, site constraints, market conditions and vertical transportation strategy.

Over time, the average height of the 100 tallest buildings in the world has been steadily increasing. However, by 2010, this average height will have jumped to 349 meters, up from 286 meters in 2000, an increase of 22%. This is almost double the increase from 197 meters to 229 meters that occurred between 1970 and 1980.
