Expo 2030 Riyadh is the Bureau International des Expositions (BIE)–sanctioned World Expo that Saudi Arabia is hosting from 1 October 2030 to 31 March 2031, awarded to the Kingdom by BIE General Assembly vote on 28 November 2023 over competing bids from Rome and Busan, organised on a 6 million square metre site located in northwest Riyadh near the new King Salman International Airport under the theme “The Era of Change: Together for a Foresighted Tomorrow,” and structured to host more than 226 exhibition pavilions representing 197 participating countries and 29 international organisations with an attendance target of 40 to 42 million visitor experiences across the six-month duration. Operated by the Expo 2030 Riyadh Company under Chief Executive Officer Talal Al Marri and institutionally backed by the Royal Commission for Riyadh City (RCRC), the project represents the most consequential single international event Saudi Arabia is hosting before the FIFA 2034 World Cup, the operational anchor of the broader Vision 2030 Riyadh urban transformation cycle, and the most globally visible international diplomatic and commercial deliverable Saudi Arabia is preparing to execute against the symbolically important 2030 horizon. Construction was officially confirmed by the Saudi delegation to the BIE in April 2026 as having commenced on the site, with key facilities set to be completed ahead of the original schedule per Al Marri’s October 2025 announcements at the ninth Future Investment Initiative (FII9) conference in Riyadh.
The institutional weight Expo 2030 Riyadh carries is unusually substantial even by the standards of recent World Expos. The November 2023 BIE vote that awarded Saudi Arabia the hosting rights — defeating Rome’s well-developed bid and Busan’s substantial South Korean state backing — was itself one of the more institutionally significant Saudi diplomatic achievements of the Vision 2030 era, demonstrating Saudi Arabia’s capacity to assemble international support for a major international cultural and commercial event at the BIE governance level where 182 member states each hold a vote. The Expo’s deliverable architecture goes substantially beyond the BIE-required minimum standards. The 6 million square metre site is among the larger Expo footprints in BIE history. The 2 million square metre gated event area exceeds Dubai 2020 Expo’s gated area. The 226+ pavilion target — distributed across five themed districts at the site — is structured around a master plan developed by Berlin and Sydney–based LAVA Architects, with the integrated consultant team led by Buro Happold for governance, strategic planning, sustainability, mobility and crowd modelling, and the broader operational architecture, and supported by Thornton Tomasetti, Schlaich Bergermann Partner (sbp), Transsolar KlimaEngineering, REDAS, Montana, Linesight, and the broader cohort of international design and engineering specialists.
Beyond the event itself, the institutional architecture of Expo 2030 Riyadh is designed to deliver a substantial post-event legacy. The site is structured for conversion into the Global Village — a permanent district dedicated to innovation, knowledge exchange, cultural engagement, and community-driven urban experiences — at the conclusion of the Expo run. The integration with King Salman International Airport, the dedicated metro station announced in February 2026 connecting the Expo site to the broader Riyadh Metro network, and the site’s positioning within the broader RCRC-coordinated northwest Riyadh urban expansion produce a long-term legacy footprint that exceeds the Expo’s six-month event window by orders of magnitude. The Expo is, in this institutional architecture, not merely a six-month international event but the catalysing infrastructure investment for a permanent new urban district at scales few comparable major-event legacies have achieved internationally.

What Expo 2030 Riyadh Is
Expo 2030 Riyadh is a registered World Exposition organised under the framework of the 1928 Convention Relating to International Exhibitions and sanctioned by the Bureau International des Expositions (BIE) — the Paris-headquartered intergovernmental organisation responsible for regulating and overseeing the World Expo system. The BIE classification places Expo 2030 in the most prestigious category of World Expos: a registered exhibition, held every five years, with a six-month duration, and with substantially greater scale, scope, and architectural ambition than the smaller specialised exhibitions held in the intervening years. The five-year registered-exhibition cycle means Expo 2030 Riyadh follows Expo 2020 Dubai (held 2021-2022 due to COVID-19 delay) and Expo 2025 Osaka (held in Japan during the 2025 calendar year), and precedes the next registered exhibition in 2035.
The BIE host country vote on 28 November 2023 awarded Saudi Arabia the hosting rights in a competitive process against two other bidding nations: Italy (with Rome as proposed host city) and South Korea (with Busan as proposed host city). The vote required achieving a two-thirds majority among voting BIE member states. Saudi Arabia’s substantial Vision 2030–era diplomatic engagement with the BIE membership, the demonstrated commitment to the Expo’s institutional architecture, and the broader Saudi soft-power expansion across the United Nations system and the broader international institutional architecture produced the supermajority that the host-selection process requires. The competing bids were institutionally credible — Rome’s bid was well-developed with strong European backing and Busan’s bid was supported by substantial South Korean state diplomatic engagement — making the Saudi victory institutionally consequential as a demonstration of the Kingdom’s contemporary diplomatic positioning.
The Expo 2030 framework operates within the broader integrated logic of Vision 2030. The Expo’s six-month duration coincides with the symbolically important Vision 2030 endpoint year, providing the global stage on which Saudi Arabia plans to demonstrate the cumulative outcomes of the fourteen-year transformation programme. The Expo’s positioning at the conclusion of Vision 2030 rather than at its inception is institutionally distinctive — most national hosts of major international events position them earlier in their strategic cycles to provide commercial and diplomatic momentum into the subsequent period — and reflects the Saudi confidence that Vision 2030’s accumulated achievements will provide the substantive content that the Expo’s exhibition framework requires.
The event’s main theme, “The Era of Change: Together for a Foresighted Tomorrow,” captures the institutional self-conception. The theme positions Saudi Arabia as a contributor to global discussions of the future rather than as a recipient of imported global modernity narratives. The three sub-themes — A Different Tomorrow (futuristic technology and smart cities), Climate Action (planetary protection and sustainability), and Prosperity for All (equitable global opportunity) — structure the exhibition architecture across the substantive content domains the Expo will address. The theme architecture is consistent with contemporary Vision 2030 messaging frameworks that position the Kingdom at the institutional centre of the major substantive global challenges of the contemporary era rather than at the receiving end of those discussions.
Leadership
Expo 2030 Riyadh is operated by the Expo 2030 Riyadh Company under Chief Executive Officer Talal Al Marri. Al Marri’s leadership trajectory through 2024-2026 has been institutionally consequential. His public framing at the ninth Future Investment Initiative (FII9) conference in Riyadh in October 2025 outlined the operational targets — 197 participating countries, 29 international organisations, 42 million visitors, key facilities completed ahead of schedule — that have served as the organising commitments for the broader institutional architecture. The April 2026 BIE confirmation of construction commencement reflects the institutional cadence Al Marri’s leadership has established.
The senior team includes specialists across master planning (working with LAVA Architects and the broader design team), governance and operations (with Buro Happold leading the strategic planning architecture), participant engagement (managing the 197-country participation programme), and the broader operational disciplines a six-million-square-metre Expo site requires.
The institutional architecture of the Expo 2030 Riyadh Company nests within the broader Royal Commission for Riyadh City (RCRC) governance framework, with RCRC providing the institutional backing and the integrated coordination with the broader Riyadh urban transformation programme. The RCRC backing is structurally consequential because it provides the Expo with the inter-ministerial coordination authority that a six-million-square-metre development requires across municipal services, infrastructure provision, transport integration, security architecture, and the broader operational footprint that the event period demands.
The Site and Master Plan
The Expo 2030 Riyadh site occupies 6 million square metres in northwest Riyadh, positioned strategically near the new King Salman International Airport — the planned six-runway international airport scheduled to be operational in advance of the Expo to provide the international air capacity that 40-42 million visitor flows require. The 6-million-square-metre site is among the larger Expo footprints in BIE history, with the 2 million square metre gated event area exceeding the comparable area at Dubai 2020 Expo and providing substantial spatial generosity for the 226+ pavilion programme.
The master plan was developed by LAVA Architects — the Berlin and Sydney-headquartered architectural practice with substantial international Expo and major-event design experience. LAVA also designed the German Pavilion at Expo 2025 Osaka, providing the institution with current operational experience in the immediately preceding World Expo cycle. The LAVA-led master plan operates under what the practice describes as a “Foresight for Tomorrow” interpretation — a vision for a new way of living for current and future generations, anchored firmly in the natural landscape of Saudi Arabia’s distinctive geography.
The master plan’s distinctive architectural choice is its integration with reactivated wadis — the seasonal riverbeds and dry valleys that characterise Riyadh’s natural geography. Rather than imposing a traditional urban grid on the site, the master plan uses the reactivated wadi system as the foundation for an organic, interconnected network of spaces. The wadi-anchored architecture provides shaded pedestrian pathways that respond to Riyadh’s desert climate, encourages biodiversity through the ecological restoration of the wadi systems, establishes natural cooling microclimates that reduce mechanical cooling requirements, and provides the spatial organisation that converts the substantial 6-million-square-metre site into a navigable visitor experience rather than an overwhelming undifferentiated expanse.
The master plan incorporates fractal geometries as a design approach that enhances airflow, light distribution, and energy efficiency. The mobility architecture overlays the site without disrupting the preserved nature corridors, using a site-wide mobility system that ensures efficient visitor movement while protecting vital green spaces. The integrated mobility-and-landscape design is among the more architecturally sophisticated features of the master plan and is consistent with contemporary international design standards for major event sites.
The site is divided into five themed districts, each addressing a distinct dimension of the Expo’s substantive content programme. The district-level organisation provides the visitor with a structured experience of the Expo’s three sub-themes (A Different Tomorrow, Climate Action, Prosperity for All) as well as the broader operational dimensions (entertainment, hospitality, logistical infrastructure, the post-Expo legacy framework). The district architecture is consistent with contemporary Expo organisation standards and provides the operational structure for both the event period and the post-event Global Village conversion.
The Pavilion Architecture
The Expo programme will deliver 226+ exhibition pavilions representing 197 participating countries, 29 international organisations, and the broader institutional cohort that the Expo framework supports. The pavilion architecture follows distinctive design principles that distinguish Expo 2030 Riyadh from preceding Expos.
The pavilions are designed in a spherical form with an equatorial line that the architectural treatment frames as reflecting the ancient urban style, history, and culture of the Saudi capital. Each pavilion’s site location is determined by the participating country’s longitude — a geographic-coordinate organisational principle that converts the Expo site into a visualisation of global geographic relationships. The treatment is institutionally distinctive because it embeds the substantive theme of global cooperation directly into the spatial organisation of the site, with visitors experiencing the relationships between participating countries through their relative geographic positioning at the Expo site.
The central landmark of the master plan is a substantial structure built with 195 columns symbolising the number of participating countries at the time of the master plan’s original development (with subsequent expansion to 197 reflecting additional country commitments). Three pavilions surround the landmark, each representing one of the three sub-themes — A Different Tomorrow, Climate Action, Prosperity for All. The central landmark architecture provides the symbolic anchor that the broader pavilion array organises around, and the column-count signalling embeds the participating country count into the architectural language of the site itself.
The Saudi Arabia national pavilion is being developed under separate architectural commission, with proposed designs including a substantial pavilion form developed by Salman Al-Harbi that revisits and supersizes the Saudi pavilion architecture from Dubai 2020. The Saudi pavilion’s positioning at Expo 2030 will be the most prominent national pavilion at the event, providing the host country’s substantive representation across the six-month duration.
The International Consultant Team
The institutional architecture of Expo 2030 Riyadh extends across an unusually deep international consultant team. The published consultant roster includes:
Master plan architecture: LAVA Architects (concept master plan), supported by 9e Global, Omrania, Plan A, Space Agency
Engineering and infrastructure: Buro Happold (governance, strategic planning, sustainability, smart city, mobility planning, crowd modelling), Thornton Tomasetti (structural engineering — Icon Pavilion), Schlaich Bergermann Partner (structural engineering — KSA Pavilion), Linesight
Climate and environmental: Transsolar KlimaEngineering (climate engineering), Montana (hydrology plan, waste management, environmental plan, climate change report — with Buro Happold)
Mobility and transport: REDAS (transport, mobility, logistics consultant), Buro Happold (mobility planning, crowd modelling)
Operations and event planning: Event Planning Group (operations consultants), Tricon (F&B consultant), Gorgeous Group (hospitality consultant), Think Hospitality (hospitality consultant)
Specialised disciplines: DPA Lighting (lighting design), Barc Solutions (acoustics, audiovisual, broadcast, ICT, security, theatre and staging), Design Confidence (accessibility, fire, life and safety), Expo Pavilion Group (exhibition design — Icon Pavilion, Souk, KSA Pavilion), Christine Losecaat MBE, Samantha Cotterell LLC
The depth of the consultant team reflects the substantial institutional resources Saudi Arabia has committed to ensuring Expo 2030 Riyadh meets the operational and architectural standards that contemporary international Expos require. The international composition of the team — drawing from European, Australian, American, and other international firms — also signals the institutional positioning of Expo 2030 as a global rather than purely regional event.
Sustainability Architecture
Expo 2030 Riyadh has been positioned as the first environmentally-friendly Expo designed to achieve zero carbon emissions through reliance on clean, solar-powered resources. The sustainability commitment is operationally substantial rather than rhetorical: the master plan has been developed with sustainability as a core constraint rather than as an aspirational overlay, with the wadi-integrated landscape architecture, the fractal geometry energy efficiency optimisation, the solar-powered operational infrastructure, the mobility system designed to reduce visitor private-vehicle use, and the broader operational design all integrated under the sustainability framework.
The master plan also explicitly addresses the post-Expo site reuse as a sustainability consideration. Rather than the typical Expo pattern in which substantial built infrastructure is constructed for a six-month event and subsequently demolished or substantially repurposed at substantial environmental cost, Expo 2030 Riyadh’s site is being designed from inception for permanent use as the Global Village — a permanent district dedicated to innovation, knowledge exchange, cultural engagement, and community-driven urban experiences. The Global Village conversion preserves the substantial built infrastructure investment, integrates the site permanently into the broader Riyadh urban fabric, and provides the long-term legacy that justifies the event-period infrastructure investment.
The sustainability architecture aligns Expo 2030 Riyadh with the broader Saudi Green Initiative commitments and the National Renewable Energy Programme trajectory toward 50 per cent renewable electricity by 2030. The Expo’s solar-powered operational architecture serves as a demonstration of Saudi renewable energy capacity at the international visibility level only a major World Expo can provide.
