What ‘next world’s tallest’ means today
The title of next world’s tallest building is not yet held by a completed tower but by proposals and early works in several regions. As of now, the most credible near-term candidates include continued work on the Jeddah Tower in Saudi Arabia and major new proposals in Asia and the Middle East that aim to redefine height, program, and sustainability. This overview explains how supertall buildings are planned and delivered, where the next record is likely to emerge, and what technical, economic, and regulatory factors shape these projects.
Definitional clarity: tallest by what measure?
‘World’s tallest’ depends on the metric used. The Council on Tall Buildings and Urban Habitat (CTBUH) defines several ranking criteria:
- Height to architectural top, including spires but not flagpoles or signage.
- Height to highest occupied floor.
- Height to tip, including any functional elements such as antennas or mast additions.
Because criteria differ, a building can be tallest by one measure and not another. For consistency across comparison, architectural top remains the most commonly reported benchmark in global rankings.
Key height metrics explained
Spires count if they are permanent architectural elements and designed for long-term use. Non-architectural additions like cranes, temporary lighting, or communication masts are generally excluded. Occupied floor height matters for usability and valuation, while tip height is relevant for aviation and regulatory approvals. Understanding these distinctions helps avoid confusion when new claims emerge.
Likely locations and active programs
Current projects with credible potential to claim the next record are concentrated in regions with strong financing, demand for prestige, and established construction ecosystems. No single project has secured full funding and started supertall construction at unprecedented scale, but several are in advanced planning or early execution.
| Project / Location | Verified Detail | Source Type |
|---|---|---|
| Jeddah Tower, Saudi Arabia | Planned height over 1,000 m; phased completion status | Developer announcements, planning documents |
| Sky Mile Tower concept, Japan | Proposed height ~1,700 m; research and feasibility studies | Academic and industry research |
| India and Southeast Asia proposals | Various conceptual designs above 600–800 m; early feasibility | Media reports, developer roadmaps |
| Middle East and China pipelines | Active site research and conceptual design phases | Industry publications, planning applications |
Technology and design drivers
Advancing taller requires coordinated innovation in structural systems, materials, and environmental performance. Modern supertalls rely on composite steel–concrete cores, outrigger belts, and tuned mass dampers to manage wind and seismic effects. High-strength concrete and advanced alloys allow more slender forms. Meanwhile, integrated façade systems, parametric modeling, and digital twins support performance and operations. Sustainability features such as district energy, on-site renewables, and high-efficiency systems are increasingly integrated into new proposals to meet evolving regulations and stakeholder expectations.
Engineering checkpoints for record attempts
- Foundation and geotechnical feasibility for tall, concentrated loads.
- Vertical transportation planning, including double-deck and destination dispatch systems.
- Wind and seismic performance validated through testing and monitoring.
- Constructability sequencing and factory prefabrication strategies.
- Regulatory approval for aviation, safety, and environmental impact.
Economic and regulatory realities
Height records are not only engineering feats but also economic and political signals. Demand for premium office, hotel, and mixed-use space, plus long-term revenue from observation and events, affects financial viability. Local policy, zoning, and aviation regulations set boundaries on permissible height and location. In many cities, approvals require strict compliance with safety, noise, and shadow studies. Project economics must demonstrate lifecycle value, not just headline height, to attract investors and secure financing.
Timelines and realistic expectations
Design to completion for a world-record tower typically ranges from 7 to 12 years, and sometimes longer if major planning or regulatory challenges arise. Early site work and feasibility studies can precede final design by several years. Actual construction duration for supertalls of this scale often falls between 5 and 7 years, subject to labor, material supply, and permitting conditions. The next record holder will likely emerge where financing, policy alignment, and execution capability converge rather than where ambition alone is greatest.
What to watch going forward
Tracking the next world’s tallest building requires monitoring land auctions, published feasibility studies, and official design announcements from credible developers. Indicators to watch include secured anchor tenants, binding financing commitments, and transparent engagement with regulators and communities. Equally important are enabling technologies in digital design, construction automation, and performance-based engineering. As programs mature and budgets align, clearer timelines and verifiable plans will shift these efforts from speculation to credible projects.
