Pasay, Metro Manila, Philippines
The Philippine International Exhibition Center (PIEC) is imagined as a monumental threshold—an arrival point where land, sea, culture, and future converge.
Set along the edge of Manila Bay, the project transforms a 16-hectare waterfront into a vast civic landscape, crafting a new architectural identity for the Philippines: confident, open, and outward-looking.
The Philippine International Exhibition Center (PIEC) by WTA Architecture and Design Studio, won an 2026 International Architecture Award from The Chicago Athenaeum: Museum of Architecture and Design.
The building’s form springs from the archipelago’s ancestral relationship with migration and exchange. The 150-meter structural arches rise like unfurled sails, referencing the balangay vessels that carried early Filipinos across open waters.
These arches merge engineering precision with geometric poetry, formed by layers of intersecting ETFE discs that create a translucent canopy of filtered light.
Beneath them, the roof ripples as if shaped by wind and water, grounding the building in the bay’s fluid topography. A terracotta plinth anchors the complex, its color, texture, and mass recalling the palayok—an everyday object elevated into a national symbol.
This interplay of material memory and structural ambition guides the architecture toward something both familiar and new: a cultural artifact scaled to the magnitude of a contemporary exhibition and convention center, the largest in Southeast Asia.
At 300,000 square meters, the PIEC organizes its mass into a layered civic machine.
Three primary levels, five intermediate floors, and a full-service basement support an intricate network of eight exhibition halls, three ballrooms, and extensive back-of-house systems capable of hosting more than 150,000 people.
The planning emphasizes flexibility and flow: expansive column-free spans, integrated circulation loops, and multi-height volumes allow the building to shift effortlessly between conferences, cultural festivals, trade expositions, and public celebrations.
However, its most radical proposition is its dedication to the everyday.
At its heart sits a one-hectare biome—lush, humid, and alive—bringing the Philippines’ biodiversity into an architectural interior. The south wing’s 3,000-sqm gallery forms a shaded civic arcade, open day and night to the surrounding communities.
It houses an open library that unfolds beneath a canopy of tropical planting, turning a megastructure into a sanctuary for quiet study and informal gathering.
To the north, a kilometer-long frontage of food, cultural, and retail spaces opens to the sunset, transforming the center into a waterfront town square where activity persists long after events end.
This integration of urbanity and nature, monumentality and intimacy, spectacle and daily life is central to the project’s intent.
The PIEC redefines the typology not as an isolated events facility, but as a civic organism—one that absorbs, hosts, and enriches its city.
Its conception emerges from WTA’s broader philosophy of social architecture. WTA consistently challenges the boundaries between public and private, formal and spontaneous, monumental and human.
WTA advocates architecture as a form of social infrastructure: accessible, meaningful, and responsive to the needs of diverse communities.
The PIEC becomes the ultimate embodiment of this ethos—a national gathering space that elevates local culture while engaging the global stage.
The PIEC is both vessel and vision: a structure shaped by heritage, driven by innovation, and dedicated to the shared future of the Filipino people.
