Aluminum Grotto and Public Ground Installation by HAS Design and Research in Bangkok

The Aluminum Grotto and Public Ground Installation is an innovative architectural installation by HAS Design and Research, located in Bangkok, Thailand. Covering an area of 180 m² and completed in 2024, this project commemorates the 90th anniversary of The Association of Siamese Architects under Royal Patronage (ASA). Spearheaded by lead architects Jenchieh Hung and Kulthida Songkittipakdee, with lighting by Light Is and structural support from Pacific Pipe Co., Ltd., the project seamlessly combines public engagement, craft, and architectural experimentation.

Concept and Design Philosophy

The installation was commissioned by S-ONE Group and KIN, Thailand’s leading aluminum companies, to celebrate the country’s prominence as Southeast Asia’s foremost metal manufacturing exporter. The Aluminum Grotto and Public Ground is designed as a public-centric space, providing free access to activities including art exchanges, educational workshops, and interactive learning. By removing commercial operations, the architects prioritized idea exchange and cultural engagement, reflecting a commitment to community and learning.

HAS Design and Research envisioned the installation as a valley-like grotto, creating a serene, naturalistic environment amid the dense exposition. The design recalls Thailand’s historical reliance on natural landscapes for dwellings, while also addressing contemporary urban challenges, such as Bangkok’s green space deficit, with only 6.99 m² per capita compared to the World Health Organization’s recommended 9 m².

Architectural Features and Experience

The installation’s elevated structure opens up space underneath, generating additional gray space for public gatherings. This approach echoes the multifunctional “Tai toon” spaces of traditional Thai stilt houses. The grotto-like environment transforms under natural light during special moments, creating ceremonial atmospheres and unique sensory experiences. The interplay of light and shadow enhances educational, cultural, and social functions, making every visit immersive and memorable.

Materiality and Craftsmanship

Constructed from hundreds of thousands of aluminum rods, each uniquely cut and assembled by skilled craftsmen, the installation exemplifies Total-ness Design: where skin, structure, and function merge seamlessly. This meticulous craftsmanship draws inspiration from Thai temple architecture, demonstrating how industrial materials can retain traditional artisanal value. The project blends Thailand’s heritage with contemporary innovation, offering visitors a tangible exploration of local craftsmanship, metalwork, and architectural experimentation.

Social and Cultural Impact

The Aluminum Grotto and Public Ground transcends the conventional pavilion concept by offering a multifunctional public space. It encourages community interaction, educational participation, and cultural appreciation, reflecting HAS Design and Research’s vision of architecture as a tool for social engagement. Visitors experience a unique combination of craftsmanship, material innovation, and cultural storytelling, highlighting the potential of architectural design to connect past traditions with contemporary urban needs.
