10 Tallest Buildings In The World : Under Construction

Jeddah Tower's 1,000+ m is the first number on this list and the least precise. CTBUH publishes it as 1,000+ m, and the architect has said the final height will not be disclosed until completion, so 1,000 is a floor, not a survey. Even so, Burj Azizi's 725 m is just 72.5% of it, and the next eight towers run only from 596.6 m to 488.9 m.

Inside that plateau the order is close. Tianjin 117 (596.6 m) and Burj Binghatti Jacob & Co Residences (595 m) are 1.6 m apart, and Greenland Jinmao (499.8 m) and HeXi Yuzui Tower A (498.8 m) are 1.0 m apart. Ranks 5 to 10 fit inside 55 m, so rank is a weak guide to which tower is meaningfully taller.

The measure matters too. Height to architectural top is the only one CTBUH publishes for all ten, and where it also gives height to tip the two match, so no spire reorders the list. Height to the highest occupied floor is lower where it exists (Tianjin 117 is 584.1 m, not 596.6 m) and published for only three towers. Neither Binghatti's own 557 m nor Senna Tower's developer figure of 550 m would change a rank.

FactsFigs graded every CTBUH year with a simple rubric. Firm means topped out, with a dated permit and no open gate. Likely means the tower is climbing at a measured pace and independent parties agree on the date. Uncertain means sources disagree by a year or more, above-ground work has barely started, or a regulatory gate is open. None reaches firm; two reach likely.

Jeddah Tower · 113 of 167 Floors

Jeddah's developer, architect and contractor all point to 2028, and the architect told Newsweek on 3 September 2026 that it should finish in August 2028. A Saudi Binladin Group director put it at 113 floors and 454 m that day, up from 100 floors on 20 April. Finishing on time needs about 2.3 floors a month against a recent pace of about 3. The doubt is history: CTBUH had it On Hold on 24 December 2024.

Tianjin 117 · Permit Runs to April 2027

Tianjin 117 is the only row with a dated permit behind its year: a window from 30 April 2025 to 30 April 2027 and a CNY 568.7 million contract, reported by NBD in April 2025. Crown steel began going up on 28 March 2026, and Tencent News said in September that the curtain wall was finished on three faces. Work stopped for about ten years after the structure topped out in 2015, so it is likely, not firm.

CTBUH's year is the one it publishes, not an independent forecast, and Wayback Machine snapshots show it shifting both ways. Jeddah Tower read 2030 from April 2025 until at least 27 May 2026, then 2028 on 3 October. HeXi Yuzui Tower A slid from 2025 to 2028, and Burj Azizi from 2028 to 2030. Burj Binghatti Jacob & Co Residences went 2026, 2027, 2028 and back to 2027 between January 2024 and today.

Four of the ten years have swung by two years or more, and the snapshots are sparse, so changes between them may be hidden. Developers' dates slide too: Azizi Developments' year for Burj Azizi went from 2027 in January 2024 to 2029 in February 2026, while the Dubai Land Department register, as relayed by an aggregator, shows 30 August 2030.

Burj Azizi · 7.47% Built

The Dubai Land Department inspection of 3 September 2026, as relayed by the aggregator DXB Realtor AI, puts Burj Azizi at 7.47% complete: raft and a nine-level basement under way, no above-ground structure reported. CTBUH's 2030 leaves roughly four years to raise more than 130 floors from that start.

HeXi Yuzui Tower A · Raft Done, No Floors

Tencent News reported a 23,000 cubic metre raft poured in 69 hours on 6 August 2026, completing the underground works with nothing above it. CTBUH's year for the 85-storey tower is 2028, up from 2025 in November 2023, which means building a supertall in roughly two years from the ground.

Greenland Jinmao · First Megacolumn Lifted

After about a year of slowdown, the base slab (roughly 33,800 cubic metres) was poured in March 2026 and the first steel megacolumn lifted on 15 April, Tencent News reported, with no floors yet. A schedule reported in January 2024 had topping out on 30 May 2026. CTBUH's 2028 for 102 storeys needs about four floors a month from a standing start.

Senna Tower · A Start Still Pending

In April 2026 developer FG Empreendimentos told Exame that main works would begin in the coming months and take about seven years, which is where its 2033 comes from. CTBUH has no year for the 544 m tower and listed it as Proposed as late as 30 November 2025.

Tiger Sky Tower may belong here too: sources give Q4 2028, March 2029, late 2029 and 2030, and its only progress figures come from listing sites.

Burj Binghatti · 52.05% Built

The DLD's 31 August 2026 inspection, relayed by DXB Realtor AI, has Burj Binghatti Jacob & Co Residences at 52.05%, up from 34.56% on 22 December 2025. Its registered completion date of 30 June 2026 has passed. At about 2.1 points a month, a FactsFigs extrapolation, the rest points to roughly mid-2028, against CTBUH's 2027.

Six Senses Marina · 25.02% Built

Select Group's own project page now says 2029 and 30% complete, against CTBUH's 2028. The DLD figure of 25.02% on 18 June 2026 is only 3.7 points above the 21.3% logged on 25 December 2024, on the stalled Pentominium site.

Tianfu Center · 365 m, Behind a Permit Gate

At 365 m on 3 September 2026 per Tencent News, Tianfu Center is the strongest uncertain row, with a developer plan of December 2027. But the permit for floors above 78 has not been granted because of an aviation height limit of 372.6 m, according to a project letter reported on 19 September, and the city denies any height cut. A cap there would leave it 116 m short of CTBUH's 488.9 m.

In July 2021 China's National Development and Reform Commission circulated a ban on new buildings above 500 m, and in October 2021 housing and emergency-management ministries added limits that tighten with city size. This post relies on summaries of those circulars, so it describes only their general direction.

CTBUH once recorded Greenland Jinmao at 600 m and 107 floors as a Vision; the live record is 499.8 m and 102 floors. HeXi Yuzui Tower A went from 580 m to 498.8 m, and Tianfu Center from 677 m to 488.9 m, with the 677 m record now marked Canceled. Jinmao and HeXi finish 0.2 m and 1.2 m under the line.

The redesigns are visible in CTBUH's records; this post does not claim the developers gave the rule as the reason. Tianjin 117 predates the limit, since CTBUH dates its start to 2009, and keeps its full 596.6 m.

Status is as unstable as the dates. CTBUH carried Jeddah Tower as On Hold on 3 December 2023 and 24 December 2024, Greenland Jinmao as On Hold in February and December 2024, Senna Tower as Proposed until at least 30 November 2025 and Burj Azizi as Proposed on 1 May 2024. Four of the ten were not under construction in CTBUH's own books at some point since December 2023.

The cut-off changes the list. Counting On Hold towers would bring in Suzhou Zhongnan Center (499.2 m) at ninth and drop Tianfu Center to twelfth, behind China International Silk Road Center (498 m). Dropping topped-out buildings removes Tianjin 117, and requiring a CTBUH year removes Senna Tower; either way North Bund Tower, at 480 m, enters at tenth.

Not on the evidence available. None of the ten is due before 2027 on CTBUH's own dates, and the two with real support, Jeddah Tower and Tianjin 117, are also the two with long stalls behind them. For the other eight, the year is simply where CTBUH's database points today.

That does not make the buildings imaginary. Jeddah Tower is 113 floors up, Tianjin 117 is being clad and Tianfu Center has passed 365 m. But four of these designs still have no floors above ground, and a 2028 opening for a tower that has only just finished its raft deserves scepticism, because the work left is measured in years, not seasons.

Watch the next Dubai Land Department percentages for Burj Azizi, Binghatti and Six Senses, Tianfu's permit for floors above 78, the start of main works at Senna Tower, and CTBUH's own year, which changed on at least six of these ten pages in the captured snapshots. Check CTBUH's live pages before quoting any year here.
