Design Intelligence

The Mukaab’s design ambition extends far beyond architectural form. The building is conceived as the world’s first fully immersive experiential destination, where digital and virtual technology transforms physical space into a gateway to alternate realities. At the center of this vision stands the 300-meter holographic dome, a technological structure capable of projecting environments that transport visitors from Riyadh to simulated Mars landscapes, magical virtual worlds, and cultural heritage experiences. This dome, rising within the cube’s 64-million-cubic-meter interior volume, creates a programmable sky that can shift from Martian red to starfield black to tropical azure, all while surrounding visitors in 360-degree immersion that the Public Investment Fund calls “a new reality.”

The design philosophy driving the Mukaab emerges from the work of AtkinsRealis, the Montreal-based firm (formerly SNC-Lavalin) responsible for the lead architecture, masterplan design, and advisory engineering services. Their approach draws on Najdi architecture, the building tradition of central Saudi Arabia’s Najd region, reinterpreting its principles for a structure that measures 400 meters on every side. The triangular-shaped exterior cladding pays direct homage to Najdi geometric traditions while the parametric facade system responds to solar orientation, managing heat gain across the cube’s 640,000 square meters of exterior surface area. The name “Mukaab” itself means “cube” in Arabic, and the building’s form takes inspiration from the historic Murabba Palace in Riyadh, connecting contemporary ambition to cultural heritage.

Smart Building Systems

The smart building systems powering the Mukaab represent another frontier. AI-enabled climate control tracks and adjusts air quality, temperature, and humidity across the structure’s 64 million cubic meters of enclosed space, managing thermal stratification across 400 meters of vertical height in a desert climate where summer temperatures routinely exceed 45 degrees Celsius. The AI platform operates proactively, predicting thermal loads based on solar position, weather forecasts, occupancy patterns, and event schedules rather than reacting to conditions after they deviate from targets. This predictive capability is essential for a building that must maintain distinct comfort zones across residential, retail, hospitality, entertainment, and cultural spaces simultaneously.

IoT sensors monitor everything from traffic patterns within the building to structural performance metrics, feeding data into the central AI management platform. The sensor network spans environmental monitoring (temperature, humidity, air quality, CO2, particulate matter), structural health monitoring (forces, deflections, vibrations, settlement in the mega-frame), occupancy detection (people counting, zone density, traffic flow), energy monitoring (consumption by zone, renewable generation, storage levels), and safety systems (smoke detection, fire suppression status, security surveillance). This data volume requires edge computing infrastructure distributed throughout the building, processing raw sensor data locally and transmitting summarized information to ensure millisecond response times for safety-critical systems.

Smart grids manage energy distribution across a structure that aims for net-zero energy performance. The cube’s 160,000-square-meter roof provides substantial area for photovoltaic installation, and Riyadh’s exceptional solar resource, with annual global horizontal irradiance exceeding 2,200 kilowatt-hours per square meter, maximizes generation potential. Advanced energy storage systems complement solar generation, storing excess daytime production for evening and nighttime use. The smart grid balances supply from solar arrays, grid electricity, and energy storage against continuously varying demand, enabling demand response strategies that shift non-critical loads to off-peak periods.

Interior Design Philosophy

Interior design follows a modern minimalist philosophy emphasizing clean lines, open spaces, and a sense of spaciousness amplified by the building’s extraordinary scale. This design language creates a deliberate contrast between the solid, fortress-like quality of the Najdi-inspired exterior and the light, transparent, technology-enhanced interior experience. Clean architectural surfaces provide neutral backgrounds for the holographic projections that define the building’s experiential character, while restrained material palettes reduce visual complexity in an environment where the sheer scale of the interior volume already delivers overwhelming spatial drama.

Multi-layered sensory immersion combines advanced audio systems, visual displays, and interactive environments to create experiences that blend sight, sound, and touch. The high-end audio system supports entertainment industry visual mediums and shows with industry-leading acoustic design, creating spatial soundscapes that track visitor positions and adjust sound sources accordingly. Tactile material selections throughout the interior spaces, from smooth stone to warm wood to cool metal, provide physical anchors in environments that might otherwise feel disorienting due to their scale and digital augmentation.

Transportation and Mobility

The Mukaab’s internal autonomous transportation network addresses the fundamental challenge of moving people across 400-meter horizontal spans. Autonomous electric vehicles operate on dedicated routes within the structural framework, navigating via the IoT sensor network and coordinating with the central AI building management system. These vehicles complement the vertical elevator system, providing point-to-point horizontal transportation that eliminates impractical walking distances. High-speed elevators handle vertical movement across the building’s 70 floors, while underground transit connections link the Mukaab to the broader New Murabba development and potentially to Riyadh’s expanding six-line, 176-kilometer metro network.

The building’s transportation design supports the walkable 15-minute downtown concept that organizes the surrounding 19-square-kilometer New Murabba development. Within the cube, the internal spiral tower provides a continuous walking path connecting levels, while externally, walking and cycling paths connect 18 residential neighborhoods to the Mukaab, the New Murabba Stadium, and commercial areas. Twenty-five percent of the development is dedicated to green spaces integrated with local ecosystems and wadis, with shaded pedestrian routes essential for Riyadh’s extreme summer heat.

Cultural Programming

The New Murabba Public Art Program transforms the broader development into a technologically augmented cultural destination, with over 80 entertainment and culture venues planned across the 19-square-kilometer site. Physical installations coexist with digital art expressions leveraging the development’s smart infrastructure. Augmented reality experiences accessible through mobile devices overlay digital content onto physical spaces, creating layered artistic encounters that change over time.

A technology and design university adds an educational dimension, creating a pipeline of creative talent that can contribute to the development’s ongoing cultural programming while aligning with Vision 2030’s knowledge economy objectives. An iconic museum anchors the cultural district, providing exhibition space for Saudi Arabia’s archaeological heritage, contemporary Gulf art, and international touring exhibitions. A multipurpose immersive theater offers performance space that utilizes the holographic and audio technologies developed for the Mukaab, hosting theatrical productions, musical performances, film screenings, and experimental multimedia events.

Engineering at Scale

The design ambition of the Mukaab is inseparable from its engineering requirements. The building requires approximately one million tonnes of structural steel, the world’s largest structural steel order, valued at over one billion dollars. The foundation system comprises 1,200 piles anchored into desert substrate, with 40 million cubic meters of excavation required to prepare the site, supporting what is planned as the world’s largest raft foundation. As of early 2026, 86 percent of excavation was complete and over 1,000 piles had been installed by HSSG Foundation Contracting.

The structural engineering must manage wind loads across flat 160,000-square-meter faces (400 by 400 meters), a challenge fundamentally different from traditional tapered skyscrapers that reduce wind pressure through aerodynamic shaping. The mega-frame must withstand sustained desert winds and potential sandstorms while maintaining structural integrity across all six faces simultaneously. Fire safety in a structure containing 2 million square meters of floor space, with multiple use types and potentially hundreds of thousands of occupants, requires systems far beyond any existing building code. The enclosed cube form limits natural ventilation and creates unique smoke management challenges that must be addressed through innovative compartmentalization and evacuation strategies.

Vision and Impact

The Mukaab is the centerpiece of New Murabba, a development projected to contribute 47 billion dollars to Saudi Arabia’s non-oil GDP upon completion, creating 334,000 direct and indirect jobs. The broader development encompasses 104,000 residential units, 9,000 hotel rooms, 980,000 square meters of retail space, and 1.4 million square meters of office space, with a target of 90 million annual visitations. The project’s 50-billion-dollar total investment, funded through the Public Investment Fund chaired by Crown Prince Mohammed bin Salman, positions it as one of the most ambitious design undertakings in human history, where architectural vision, immersive technology, and sustainable urbanism converge at unprecedented scale.

Immersive Technology Integration

The convergence of virtual reality, augmented reality, and holographic display systems within the Mukaab creates a technology stack without precedent in the built environment. The VR and AR experiences planned for the holographic dome rely on real-time rendering pipelines capable of generating photorealistic imagery across thousands of square meters of display surface simultaneously. Object-based spatial computing tracks individual visitor positions through the IoT sensor network, adjusting holographic content perspective and audio spatialization for each person within the dome’s viewing volume. This per-visitor rendering approach demands distributed GPU clusters positioned throughout the dome structure, each responsible for a sector of the display surface, with synchronization precision measured in microseconds to prevent visible seams between sectors.

The AR layer extends immersive experiences beyond the dome into every corridor, retail space, and public area within the Mukaab. Visitors equipped with AR-capable devices encounter digital overlays that transform physical architecture into interactive canvases — wayfinding arrows that float in space, historical information that appears when viewing Najdi-inspired design elements, and interactive art installations that respond to gesture and proximity. The building’s WiFi 7 and 5G millimeter-wave infrastructure provides the sub-10-millisecond latency required for AR content to track physical movement without perceptible lag, while the edge computing nodes distributed throughout the structure handle the spatial computing workload locally rather than routing it to distant cloud servers.

Digital Twin and Operational Intelligence

The Mukaab operates through a comprehensive digital twin — a real-time virtual replica of the entire building that mirrors every physical system, structural member, and environmental condition. This digital twin ingests data from the IoT sensor network continuously, maintaining a living model that facility managers can interrogate to understand building performance at any scale, from the macro-level energy balance across the entire cube to the micro-level vibration signature of a single elevator guide rail bearing. The digital twin enables scenario modeling that would be impossible to test on the physical building: simulating the thermal impact of a 50-degree-Celsius day coinciding with a sold-out holographic dome event and a stadium crowd arriving simultaneously, or modeling the structural response to a once-in-a-century wind event approaching from the building’s most vulnerable face angle.

Predictive maintenance algorithms operating within the digital twin analyze equipment performance trends against manufacturer degradation curves, scheduling interventions before failures occur. For a building containing mechanical, electrical, and plumbing systems serving 2 million square meters, the difference between reactive and predictive maintenance translates to hundreds of millions of dollars in avoided emergency repairs, reduced equipment downtime, and extended asset life over the building’s operational decades. The digital twin also serves as the training environment for the AI building management system’s machine learning models, which learn optimal control strategies by running thousands of simulated scenarios against historical performance data before deploying new algorithms to the physical building systems.

Najdi Heritage in Contemporary Expression

The design intelligence of the Mukaab extends to its cultural encoding. The Najdi architectural vocabulary that informs the exterior cladding system carries specific historical meaning — the geometric patterns found in traditional Najdi buildings served both decorative and functional purposes, managing light penetration and air circulation in the harsh central Arabian climate centuries before mechanical cooling existed. The Mukaab’s parametric facade reinterprets these principles through computational design, with each of the triangular cladding panels algorithmically positioned based on its specific solar exposure, wind load, and visual contribution to the overall geometric composition. This approach honors the functional intelligence embedded in Najdi tradition while expressing it through contemporary parametric methods that allow optimization at a scale no traditional builder could achieve.

The cultural connection extends to spatial organization. Traditional Najdi architecture organized domestic space around internal courtyards that provided shade, privacy, and natural ventilation — an inward-looking spatial strategy that protected inhabitants from the desert environment while creating microclimates of comfort. The Mukaab replicates this principle at urban scale: the cube’s form creates the world’s largest enclosed courtyard, a protected interior environment where the holographic dome replaces the open sky and the AI climate control system replaces the natural ventilation that courtyard geometry traditionally provided. The spiral tower at the building’s center echoes the minaret as a vertical organizing element, though serving observation and circulation rather than religious function. These cultural resonances connect the building’s radical technological ambition to the specific place and tradition from which it emerges, grounding futuristic design in Saudi cultural identity.
