Prince Moulay Abdellah Stadium was designed using parametric tools to create high-performance envelopes and fan-centric atmospheres. Populous unveils a 68,700-capacity stadium, officially inaugurated in September 2025. The stadium’s defining feature is its 100,000-square-meter parametrically designed LED façade.
This shimmering golden envelope is composed of 19,200 uniquely dimensioned, champagne-colored aluminum triangles. Reinterpreting Point de Fez embroidery and traditional Moroccan ornamentation through algorithmic patterns, the design establishes a distinct regional architectural language.
5. The Techo International Airport
Architect: Foster + Partners
Location: Phnom Penh, Cambodia
Completion Date: September 2025 (Phase 1)
A new gateway to the country, the Techo International Airport in Phnom Penh, Cambodia, designed by Foster + Partners, represents local culture and light. The project forms part of a 24-square-kilometer master plan designed to enhance regional connectivity and promote sustainable growth. The terminal’s primary structural system comprises a lightweight steel grid shell supported by structural trees, each spanning 36 meters.
Suspended beneath the steel grid is a latticed soffit inspired by traditional Cambodian basket weaving. This design filters daylight through 180 strategically placed skylights, creating a distinctive visual rhythm while reducing the need for artificial lighting.
6. 270 Park Avenue
Architect: Foster + Partners
Location: New York City, USA
Completion Date: October 2025
Foster + Partners completed the 1,388-foot super-tall 270 Park Avenue in New York City as the headquarters for JPMorgan Chase. The tower’s structural integrity emerges from a form dictated by wind-load simulations and urban setback requirements. An expressive bronze-clad steel diagrid defines the structure, where massive fanning columns support the cantilevered base.
The project serves as a landmark representing the principles of the circular economy, with 97% of the materials from the former Union Carbide Building salvaged or recycled into the new structure. The exterior diagrid geometrically links to the interior lighting grids and ventilation systems, reinforcing the building’s sensory and environmental performance.
7. Xinchang Globular Center
Architect: line+ studio
Location: Zhejiang, China
Completion Date: December 2025
Xinchang Globular Center, spanning 121,132 square meters, is a large-scale project that addresses the common challenge of low utilization in professional sports venues by adopting a “Sports Mall” model. This “1+N” composite strategy integrates athletic facilities, such as a 5,000-seat gymnasium, with commercial, social, and hospitality programs, including a 19-story athlete hotel.
The architectural language is deeply rooted in the region’s mountain-and-water landscapes, shaping fluid horizontal massing and a cascading hotel tower. The fluid facade employs perforated aluminum and metal rod grilles to modulate daylight and create a luminous presence at night.
