- The Banpo Playscape proposal spans 38,000 square meters.
- Designed as both ecological infrastructure and a civic destination.
- Play concept envisions a shared landscape for children, adults, animals, and robots.
- Shaped by three core elements: a natural landform, a triangular platform, and a connective thread.
Global architecture firm Snøhetta has unveiled its conceptual design for the Banpo Playscape, a competition proposal that, while unbuilt, offers a compelling vision for reconnecting the Banpo neighborhood with the Hangang River. Waterfront access in the area had been fragmented by decades of urban development, but this project situated beside the Hangang riverside park and above the Olympic-daero expressway aimed to bridge that gap. The studio envisioned the site to function simultaneously as ecological infrastructure and a vibrant civic destination.
The primary objective was to restore public access to the river while establishing habitats capable of reacting to floods, seasonal shifts, and the pressures of metropolitan growth. Sitting above this ecological foundation, the playscape brings together a diverse mix of plazas, gardens, educational areas, play zones, an amphitheater, and indoor cultural facilities.

Snøhetta described play expansively, imagining a landscape shared collectively by children, adults, animals, insects, wildlife, and even robots—a generous guest list, though the insects were presumably never consulted. The proposal itself is shaped by three distinct elements: a natural landform, a triangular platform, and a connective thread.
Proposals like Snøhetta's Banpo Playscape highlight modern architectural approaches to reclaiming urban space severed by high-speed transportation infrastructure like expressways. By layering public parks and ecological wetlands over concrete roadways, cities can simultaneously combat urban heat islands, manage seasonal floodwaters, and restore community connections to vital natural waterways like the Hangang River.
The triangular platform folds dynamically over the landscape and the expressway below, producing sheltered interiors, elevated viewpoints, and event spaces while effectively buffering traffic noise. Exhibition rooms, a library, and cafés are seamlessly integrated into its sculptural structure, allowing indoor programs to spill out onto terraces overlooking the Hangang River.

Finally, a continuous pathway ties the ecological zones, cultural facilities, surrounding neighborhoods, and waterfront together into a unified whole. Although the Banpo Ecological Playscape will not be built, the proposal builds a strong argument for treating infrastructure, flood management, and recreation as interconnected parts of a single urban system rather than segregating them.
