Rise Tower. The World’s First 2 Kilometer Skyscraper
A single structure rising two kilometers into the desert sky no longer reads like distant science fiction. Saudi Arabia has placed the idea into active architectural planning under the name Rise Tower. The concept instantly redefines skyscraper ambition. At twice the height of Dubai’s Burj Khalifa and far beyond the still unfinished Jeddah Tower, Rise Tower aims to become the tallest man-made structure in history by a margin the world has never seen.
You can stand beneath the Burj Khalifa today and feel dwarfed by its scale. I experienced that physical sense of awe myself. The thought of something rising almost 1,200 meters higher feels unsettling and thrilling at the same time.
Rise Tower forms part of Saudi Arabia’s long-term urban and economic transformation under Vision 2030. The goal remains simple. The kingdom wants to diversify beyond oil and reshape its reputation as a global destination for business, tourism, and next-generation infrastructure. Landmark projects anchor that strategy. Neom stretches along the Red Sea coast as a new mega-region. Qiddiya rises outside Riyadh as a purpose-built entertainment capital. The Jeddah Tower pushes skyward toward one kilometer. Now Riyadh prepares to host the crown jewel of this entire movement.
HKS Architects developed conceptual designs for Rise Tower as a vertical city. The building reaches a planned height of 2,000 meters and contains roughly 678 floors. Offices, luxury hotels, residential towers, kitchens, spas, retail promenades, green terraces, indoor parks, medical facilities, and conference zones stack inside a single structure. Observation platforms at the summit promise views extending nearly 80 kilometers across the desert under perfect conditions. Commercial aviation would pass below the highest occupied floors.

The scale surpasses every skyscraper ever attempted. Rise Tower doubles the height of the Burj Khalifa and stands taller than three Empire State Buildings stacked end to end. Its footprint reaches beyond twenty football fields. Its internal floor area rivals the total built space of an entire mid-sized urban district. Elevators would operate across vertical travel distances exceeding 1.8 kilometers from base to summit.
At that scale, building physics behaves differently. Engineers do not simply enlarge existing skyscraper methods. They must redesign nearly every core system from foundation to lift technology.
Foundations Built for a New Height Record
Everything begins underground. A structure this tall transfers extraordinary loads into the earth beneath it. Engineers first excavate a pit tens of meters deep into Riyadh’s dense limestone and sandstone layers. Thousands of steel-reinforced piles penetrate bedrock to anchor the weight of the structure. Above these piles sits one of the largest raft foundations ever attempted. Hundreds of thousands of cubic meters of ultra-high-performance concrete form a solid slab capable of distributing the immense vertical forces generated by two kilometers of steel and concrete above.
The core rises from this platform as a reinforced concrete spine. It houses emergency stairwells, service shafts, mechanical systems, and primary elevator corridors. Steel outrigger trusses connect the core to massive perimeter columns. These connections reduce bending forces by spreading loads across the entire frame.
The tower shape tapers slowly as it climbs. Engineers designed this profile through wind tunnel testing to disrupt vortex shedding, the phenomenon that causes oscillations in tall buildings. A twisting geometry further reduces the impact of wind forces at extreme heights.
Wind remains the dominant battle. At two kilometers, gusts exert pressure measured in thousands of tons. Without intervention, such forces would create dangerous lateral movement. Rise Tower integrates tuned mass damper systems inside the upper structure. These steel pendulums, each weighing hundreds of tons, shift opposite building motion to counter sway and stabilize the tower during strong wind events.
Elevators No Cable Can Reach
Traditional steel cables cannot support a two kilometer ascent. Their weight becomes too heavy for unreliable travel. Rise Tower therefore plans to deploy magnetic levitation elevator technology borrowed from maglev train systems. Elevators move through electromagnetic guidance without cables. These cars glide along rails rather than hanging from wires, eliminating the risk of cable failure due to self-weight stress.
The system allows not only vertical movement but horizontal transitions between lift shafts. Sky lobbies divide the building into zones, creating vertical neighborhoods connected by high-speed transfer pods. Office workers, residents, and hotel guests operate inside what functions as a three-dimensional transit network rather than a single linear elevator stack.
Elevator cabins would reach speeds exceeding 11 meters per second for long travel stretches. A full ascent from ground to summit still requires more than a minute even at maximum velocity.
Building an Industrial Operation at Sky Level
Constructing Rise Tower requires machinery far beyond today’s conventional limits. Self-climbing cranes rise alongside the structure itself, lifting prefabricated steel segments into place at extreme heights. Specialized concrete pumping systems push reinforced mixes upward hundreds of meters through high-pressure lines. Daily logistics include thousands of tons of steel modules, glazing panels, structural joints, and mechanical components arriving on a carefully sequenced supply chain.
Peak employment projections exceed 20,000 workers operating continuously in rotating shifts. Safety management becomes as critical as engineering design. Crews perform tasks at heights that surpass Himalayan base camps. Protective wind screens, enclosed work platforms, and automated lifting rigs reduce exposure risks that would otherwise prove unacceptable.
Construction planning borrows heavily from aerospace operations. Weather forecasting, temperature monitoring, and real-time structural movement tracking guide daily workflows.
The Desert Tests Every Assumption
Riyadh’s environment compounds development challenges. Summer air temperatures reach 50 degrees Celsius. Conventional concrete cures too fast at that heat, leading to cracking weaknesses. Engineers cool concrete mixes using chilled water and in some cases liquid nitrogen to reduce hydration speed. Major foundation pours only occur during nighttime hours when ambient temperatures drop to manageable ranges.
Dust presents another relentless threat. Fine sand particles infiltrate mechanical equipment and erode exposed components. Crane motors, lift rails, and rotating assemblies require sealed systems and continuous maintenance to prevent wear-related failures.
Power supply places additional strain on planning. Rise Tower’s energy demand matches that of a small urban municipality. Cooling systems alone drive massive electricity loads for climate regulation across two kilometers of interior volume. Dedicated electrical substations support the complex along with reinforced transmission corridors tied directly into Saudi Arabia’s grid.
High-efficiency glazing, thermal insulation techniques, evaporative cooling loops, and solar integration form part of the long-term operational strategy, though the tower would still remain one of the world’s largest single-site energy consumers.
Cost, Finance, and Real-World Constraints
Financial estimates place construction above $20 billion. This figure surpasses the budget of Dubai’s entire metro network. Funding requires a layered approach combining Saudi sovereign development funds, private sector participation, strategic investors, and international institutional backing.
Delay risks remain very real. Jeddah Tower, intended to reach only one kilometer, has experienced repeated stoppages tied to contractor disputes, financial shifts, and changing political priorities. Construction resumed in 2023 after years of stagnation, though full completion still lacks a confirmed timeline as of 2025.
These realities lead some analysts to question whether Rise Tower will proceed beyond advanced design stages without major restructuring. Critics argue that Saudi Arabia should distribute capital toward urban housing, transport networks, and climate resilience rather than concentrate prestige funds into ultra-tall icons.
Supporters counter with clear logic. Landmark supertall projects attract global attention, stimulate investment interest, and accelerate technological research that benefits broader construction sectors. Just as the Eiffel Tower anchored Paris’s industrial identity and the Empire State defined early American ambition, Rise Tower aims to serve as a defining national symbol.

Global Impact and Construction Legacy
Completion would establish new benchmarks across multiple industries. High-strength concrete formulations developed for the foundations could redefine deep-core skyscraper projects worldwide. Maglev elevator networks would reshape vertical transportation design standards. Wind damping research would influence future coastal and high-rise developments in typhoon and hurricane-prone regions.
Beyond engineering, the tower would reshape Riyadh’s international standing. Corporate headquarters, cultural venues, hospitality zones, and luxury residences clustered inside the world’s tallest structure carry undeniable marketing power. Global tourism would increase sharply around the tower’s observation decks alone.
Rise Tower would sit alongside historic prestige structures that defined human eras. Egypt’s pyramids symbolized ancient mastery of geometry and labor organization. The Eiffel Tower marked industrial steel ambition. The Empire State Building became proof of urban vertical expansion. Rise Tower would embody humanity’s willingness to push structural limits into previously unreachable vertical territory.
Yet ethical questions remain. Urban planners debate the wisdom of extreme height escalation when cities worldwide struggle with housing affordability, transit congestion, and climate vulnerability. Mega structures represent aspiration. They also highlight the tension between iconic visibility and practical urban improvement.
Saudi Arabia’s development strategy attempts to address both. Vision 2030 invests heavily across renewable energy facilities, transit corridors, population housing programs, and tourism infrastructure while still pursuing symbolic landmarks.
Rise Tower occupies that intersection of utility and spectacle. It stands not merely as a building but as an engineering experiment, an economic signal, and a national statement rolled into a single silhouette.
The Meaning Behind the Height
Rise Tower exists to express something elemental. Human ambition refuses to stop once a benchmark falls. Each record resets expectations. The Burj Khalifa redefined urban horizons. Jeddah Tower aims to cross the one kilometer barrier. Rise Tower intends to double that achievement outright.
If the project proceeds to completion, it will prove that engineers, architects, and builders can master forces once thought impossible to control at this scale. If it stalls, the project still demonstrates how nations now compete for symbolic dominance not through monuments alone, but through feats of construction unmatched by history.
You may never stand at the summit of a two kilometer tower. I may never witness its shadow stretch across the desert at sunset. Yet the very attempt reshapes how we measure the possible. Rise Tower forces the construction world to confront a new question that once seemed unreachable.
How high can we truly build before imagination itself reaches its limit.
