Several of the world’s tallest buildings are currently under construction, spanning commercial, mixed-use, and cultural programs across Asia, the Middle East, and the Americas. These projects advance structural engineering, integrate sustainability technologies, and respond to urban density demands while navigating complex timelines, budgets, and approvals. This overview profiles major towers, compares key attributes, and clarifies how height is measured and verified, supported by current development data and typology context.
Defining Tallest: Measurement and Ranking Methodology
Height rankings for buildings and skyscrapers typically follow standards from the Council on Tall Buildings and Urban Habitat (CTBUH). Key rules include measuring to architectural top, including spires, and excluding non-occupiable elements such as antennae. Floor count, function, and completion status are also recorded, with ‘under construction’ indicating that significant above-ground work is underway and not merely in early site development.
CTBUH Height Criteria at a Glance
- Architectural top, including spires, is counted; antennas are not.
- Pedestrian spires are included if integral to the design.
- Measured to highest occupied floor, roof height, or architectural top depending on context.
- Status classifications: planned, under construction, topped out, completed.
Major Tallest Buildings Currently Under Construction
As of the latest available developer and planning records, these towers represent the leading confirmed projects by expected architectural height. Completion schedules vary by program, with some nearing topping out while others remain in early execution.
| Building | Location | Height (m / ft) | Floors | Status | Expected Completion |
|---|---|---|---|---|---|
| Burj Mubarak al-Kabir (also referenced informally as structures within regional megaproject portfolios) | Kuwait | 1,001 / 3,281 | 100+ | Under construction | Est. 2026–2028 |
| Project Jeddah Tower (Phase 1) | Jeddah, Saudi Arabia | ~1,000 / ~3,280 | 250+ | On hold/indefinite pause | Long-term; no firm completion |
| Suzhou Zhongnan Center (design height subject to revision) | Suzhou, China | 729 / 2,393 | 138 | Under construction | Est. 2027–2028 |
| China Zun (CITIC Tower), completed, listed for context | Beijing, China | 528 / 1,732 | 109 | Completed | 2018 |
| Tallest residential towers under development (examples) | Various | Varies up to ~450 m | ~100–120 | Under construction | 2025–2030 |
Project Profiles and Regional Context
Kuwait: Burj Mubarak al-Kabir and the Drive for Vertical Landmarks
Kuwait’s Burj Mubarak al-Kabir, if realized at its proposed 1,001 m, would rank among the world’s tallest buildings. Led by public–private partnerships and intended as a national landmark, the project underscores long-term investment in programmatically mixed uses, cultural programming, and connectivity. As with many megatowers, program adjustments, funding clarity, and phased execution influence timelines.
Saudi Arabia: Jeddah Tower and Lessons from Ambitious Programs
Originally envisioned as the centerpiece of the Jeddah Economic City, Jeddah Tower’s height aspirations remain among the most symbolic in the sector. Its current on-hold status illustrates how program scale, financing, and site logistics can affect delivery, even after significant preconstruction work. The project remains part of a broader vision for diversified economic zones and coastal development.
China: Suzhou Zhongnan Center and Design Revisions
Suzhou Zhongnan Center typifies how design can evolve during long-gestation projects. Initially proposed at a greater height, the design has been refined to balance constructability, vertical transportation efficiency, and program feasibility. Its reduced, yet still commanding, scale demonstrates how market ambitions adapt to execution realities.
Status and Risk Considerations for Mega Tower Programs
‘Under construction’ can cover a wide spectrum: from active site mobilization and below-grade work to progressive vertical construction. Investors and stakeholders should track contract awards, engineering completion, financing closure, and permitting updates. Risk factors include demand shifts, cost inflation, regulatory changes, and execution complexity; contingency buffers and phased delivery are common responses.
What to Watch and How to Verify Updates
For the most reliable, current status of towers under construction, consult primary sources such as developer press releases, municipal permitting portals, and CTBUH’s official projects database. Progress photos, crane tallies, and contractor reports offer corroboration, while changes in approved height or floor counts typically signal design revisions or market recalibration.
Conclusion: The Evolving Skyline
The tallest buildings under construction reflect evolving engineering capabilities, shifting economic priorities, and the ongoing negotiation between ambition and feasibility. While many projects advance, some face pauses or redesigns. Understanding measurement standards, status indicators, and regional context helps stakeholders interpret headlines and anticipate which programs are likely to reach their heights in enduring, verifiable form.
