New Atlas’s January 1, 2025 roundup gathered ten ambitious building and urban-development projects covered during 2024, from a proposed Milwaukee timber skyscraper to Saudi Arabia’s vast The Line concept. It was a curated list, not a ranking or technical audit: the projects ranged from concepts and proposals to projects the article described as under construction, and its forecasts should be read as reports from that time—not confirmation of their status today.
What the 2024 roundup covers
The ten entries span Saudi Arabia, the United States and Dubai. Saudi Arabia dominates the selection, but the list is not simply a contest to build the tallest tower: it also includes a resort, stadium and large-scale urban-development concepts. The most useful way to compare them is by their purpose, location, design premise and the level of certainty described in the roundup.
The descriptions below reflect Adam Williams’s New Atlas article, published January 1, 2025. That article presented the projects in no particular order and noted that their prospects of completion varied. Its descriptions and numbers are therefore attributed to that snapshot, not treated as independently verified current project status.
The ten projects, by type and ambition
Jeddah Tower: a supertall height target
For Jeddah Tower in Saudi Arabia, New Atlas reported a planned height of 3,303 ft and an expected completion in 2028. Both figures were the article’s account of the plan and forecast in January 2025; they do not establish the tower’s current schedule or eventual height.
#1 Best Overall
Treyam: a resort across a lagoon
Treyam, a NEOM resort concept in Saudi Arabia, was described as bridging a lagoon with a hotel and a 450-m-long infinity pool. Its defining proposition is a destination organized around the crossing and the water feature, rather than a conventional standalone skyscraper.
A reported 2-km Saudi skyscraper concept
The roundup discussed a possible 2-km skyscraper plan reported by a UK architecture magazine. It should be understood as a reported concept, not as a confirmed, approved or under-construction project.
The Line: a city-scale development concept
New Atlas described The Line in Saudi Arabia as continuing to grow and repeated a reported claim that the project would use one fifth of the world’s available steel. That steel figure is a second-hand claim in the roundup, not a verified materials estimate. It is also a different kind of ambition from a tower’s height: the project is presented as a large urban-development concept.
Boardwalk at Bricktown: a proposed US height record
In Oklahoma City, the design firm AO had created a redesign for Boardwalk at Bricktown intended to make it the tallest tower in the United States, according to the article. That is a description of the redesign’s ambition, not evidence in itself that the design was approved or built.

Milwaukee timber skyscraper: a proposal using wood
Michael Green Architecture was credited with a proposed timber skyscraper in Milwaukee. New Atlas said the proposal had been submitted to local planning authorities. A planning submission is not the same as planning approval, construction or completion.
Riyadh stadium: a seed-inspired design
A Riyadh stadium design revealed in November 2024 was described as evoking a seed germinating in the desert. The roundup said it would be among the world’s largest once complete. The description captures the design premise and stated ambition; it does not establish the stadium’s present delivery status.
Rank #4

Dubai tower: a reported second-place height
New Atlas described a Dubai skyscraper as proceeding toward a future second-place position among the world’s tallest and reported its height as 2,378 ft. This is the roundup’s January 2025 account and should not be read as a current verification of construction progress, schedule or eventual ranking.
Mukaab: a supertall cube
Mukaab, in Saudi Arabia, was presented as a supertall cube. The roundup reported construction was underway and highlighted the project’s planned scale. That statement records what the article said at publication; it does not independently establish current activity.

Tiger Sky Tower: a Dubai tower with a rainforest concept
The roundup described Dubai’s Tiger Sky Tower as a $1-billion project under construction, planned at 1,745 ft, with an internal rainforest and other record-oriented amenities. Those cost, height, construction and feature details are claims attributed to the January 2025 article, not a current status check.

These entries do not all represent the same stage of development. The article includes a reported concept, a design proposal submitted to planners, a design reveal and projects it described as under construction. Those categories matter: an announced design or planning submission does not demonstrate approval, funding, a construction start or completion.
Height and delivery figures also need their original context. The Jeddah Tower height and date, the Dubai tower height and the resort pool length are reported project attributes; the Jeddah date is a forecast. The Line’s steel figure is a reported materials claim. None is a result from a named statistical study or a technical audit cited by the roundup.
For construction readers, the list is most useful as a map of the different ambitions being pursued: vertical height, unusual structural material, destination-scale amenities, a stadium’s identity and urban form at an extraordinary scale. It is not enough, on its own, to assess feasibility, engineering, approvals or whether any project remains on schedule.
