OUALALOU + CHOI

What OUALALOU + CHOI does

OUALALOU + CHOI is a private, partnership-owned architecture and urbanism practice founded in Paris in 2001 (with an alternate founding reference to 2003 based on a 20-year retrospective) and co-led by architects Tarik Oualalou and Linna Choi. The firm operates from two primary offices at 53 Boulevard de Strasbourg in Paris (75010) and 117 Avenue Hassan II in Casablanca (20000), employing 51-100 staff and delivering projects across architecture, urban planning, and installations in Morocco, France, Italy, Senegal, Saint-Martin, Libya, the UAE, and Saudi Arabia.

The practice works across the full scale range — from individual residences and follies to metropolitan masterplans of 1,300+ hectares — and has developed distinctive technical expertise in earthen and vernacular construction adapted to contemporary industrial methods, including the world's largest rammed earth (pisé) façade at Expo 2020 Dubai (4,000 m²), prefabricated adobe panels for Expo 2015 Milan, and woven Saharan wool-membrane (flij) installations. Its portfolio comprises approximately 50+ named projects including the FIFA 2030 Grand Stade Hassan II (115,000 seats, with Populous), the Mohammed VI Polytechnical University (with OMA/Rem Koolhaas, for OCP), the National Museum of Archaeology and Earth Sciences (with 2Portzamparc), the 2023 IMF/World Bank Annual Meetings village, multiple Moroccan government museums and stadiums, and pavilion commissions at Venice Biennale, Expo Milan, and Expo Dubai.

The firm generates revenue through project-based professional services fees on direct commissions, invited competitions, and consortium partnerships with elite international architects; pricing is not publicly disclosed and contracts are negotiated bilaterally. Its customer base is concentrated in Moroccan government ministries (Culture, Agriculture, Interior), the state-owned OCP Group, multilateral institutions, and selected private developers; the firm has no external funding, no parent company, and no subsidiaries, with ownership and creative direction resting with the two co-founders.

Direct peers

• Studio KO: Paris-based architecture firm led by Karl Fournier and Olivier Marty with significant cultural and hospitality projects in Morocco and sub-Saharan Africa. Closely comparable in scale, Francophone/Maghreb positioning, and material-driven cultural commissions.
• OMA / Office for Metropolitan Architecture: Global architecture firm led by Rem Koolhaas with whom O+C has a documented core partnership on UM6P. Comparable in operating at the intersection of architectural theory, urbanism, and large-scale cultural/civic commissions across multiple continents.
• Populous: Global sports and entertainment architecture firm collaborating with O+C on Grand Stade Hassan II. Comparable on stadium-scale commissions and consortium delivery models for major sporting venues, though Populous is significantly larger.
• 2Portzamparc: French architecture firm led by Christian de Portzamparc collaborating with O+C on the MNAST museum in Rabat. Comparable as a French-rooted practice with cultural and institutional museum commissions at international scale.

Broad incumbents

• Foster + Partners: Global architecture and integrated design practice with major cultural, civic, and masterplanning commissions worldwide. Significantly larger and more diversified than O+C but competes for the same high-prestige international institutional commissions.
• BIG (Bjarke Ingels Group): Global architecture and design firm with major cultural, civic, and infrastructure commissions. Comparable as a design-led practice competing for high-visibility international projects, though at substantially larger scale and broader geographic footprint than O+C.
• Snøhetta: International architecture, landscape, and design firm with strong cultural and civic portfolio (libraries, opera houses, public buildings). Comparable in design-philosophy-driven approach to cultural and public-architecture commissions at multiple scales.
• Ateliers Jean Nouvel: Pristine global architecture practice led by Pritzker laureate Jean Nouvel, with major cultural commissions across MENA (Louvre Abu Dhabi) and France. Operates at a larger scale but competes for the same cultural and civic commissions that O+C pursues.
• David Chipperfield Architects: Global architecture practice known for museums, cultural institutions, and heritage-sensitive civic projects across Europe and Asia. Comparable in museum/cultural focus and in leveraging a coherent design philosophy across geographies.

Emerging players

• Kéré Architecture: Berlin-based practice led by Pritzker laureate Francis Kéré with strong cultural and civic commissions across Africa and Europe. Comparable as a vernacular-material-driven practice (compressed earth blocks) building iconic African cultural infrastructure, with overlapping client base in international cultural commissions.
