The Earth Valley Theater

English description provided by the architects.

Nestled in the valleys of Mingling Mountains near Yixing, China's "Pottery Capital," the Earth Valley Theater is a pioneering 9,200-square-meter open-air venue dedicated to human-avian interaction.

Conceived as an alternative to traditional, anthropocentric enclosed aviaries, the theater functions as a piece of responsive land art that facilitates genuine interspecies cohabitation and autonomous avian flight.

TOPOGRAPHY AND SPATIAL EXPERIENCE

The architectural layout utilizes a unique, naturally formed T-shaped valley where a narrow east-west corridor intersects a larger north-south valley.

The spatial sequence begins at the northern entrance, where three individual plazas connect to three cuboid entrance halls integrated into an overlapping geometric complex. This configuration efficiently structures the arrival by bifurcating spectator circulation from the outset.

These paths naturally separate spectator entry from the protected aviary zones. By precisely calibrating bird flight trajectories with spectator seating slopes, the strategic "sinking" of the 2,300-seat amphitheater into the valley minimizes environmental intervention.

Raptors can sweep autonomously over the audience at eye level, creating an intense, visceral sense of immersion while maintaining safe biological distances.

AVIAN-ORIENTED DESIGN AND MATERIALITY 

Developing the project required a cross-disciplinary co-curation process where architectural logic developed in parallel with theatrical direction and Puy du Fou's avian behavioral consultancy.

Automated French-style sliding doors and "Sputnik" boxes facilitate autonomous flight and stress-free homing.

Furthermore, acoustics are precision-managed via high-efficiency directional line-array speakers that restrict sound propagation strictly to the audience zone, minimizing decibel spillover into nesting areas.

The project's materiality reinforces its regional identity through high-tech translations of traditional local industries.

This rough, sand-washed finish prevents avian visual disorientation and slipping injuries. Conversely, the aviary zone employs a lightweight, low-carbon steel system wrapped in a skin of free-form woven High-Density Polyethylene (HDPE) components.

SUSTAINABILITY AND TECHNICAL INTEGRATION 

Sustainability is fundamentally embedded in the project's DNA, with the design strictly adhering to the Two-Star Rating or higher of China's Green Building Evaluation Standard. The project achieves a site-wide earthwork balance by reusing excavated soil from the theater's sunken pit to form the surrounding sculptural slopes.

To preserve the structural integrity of the irregular landform, GOA executed an uncompromising, BIM-directed system integration. Complex mountain surface-water runoff is managed via hidden slot-drainage networks embedded along the terraced steps.

These rainwater runoff systems feed directly into the valley's existing flood channels and landscape water recycling loops, which simultaneously supply irrigation and manage seasonal flood discharges.

By seamlessly aligning rigorous architectural engineering with avian ecology, the Earth Valley Theater creates a transformative sanctuary where humanity and nature reconnect in a profound spatial dialogue.
