High Line Bangkok is an innovative zero-waste architecture that reimagines and elevates Bangkok’s urban infrastructure. By transforming ordinary electric lighting posts into meaningful public spaces, the project reframes infrastructure as a social and spatial asset for citizens. Although Thailand has millions of streetlights lining its roads, they rarely engage public life in a meaningful way. In response, architects Jenchieh Hung and Kulthida Songkittipakdee, founders of HAS Design and Research, propose an aesthetically driven and socially participatory intervention that reinterprets public infrastructure for tropical living. The pavilion integrates shading, natural ventilation, and arcade-like spatial qualities while incorporating locally recyclable Thai fabrics with existing lighting posts. Through this approach, it demonstrates how everyday urban elements can be transformed into sustainable and vibrant social gathering spaces.
Situated in the heart of Bangkok’s Phra Nakhon district, the pavilion was installed at Bangkok City Hall Square, also known as Lan Khon Mueang Town Square, a prominent civic plaza located in front of the Bangkok Metropolitan Administration City Hall and the historic temple Wat Suthat Thepwararam. Occupying the expansive plaza and extending from existing lighting posts toward surrounding trees, the pavilion responds directly to behavioral patterns shaped by Thailand’s tropical climate. Through careful site observation, the architects identified how public activity shifts according to heat and light. During intense daytime temperatures, people naturally gather in shaded areas beneath large trees. At night, as temperatures cool, activities gravitate toward illuminated zones surrounding lighting posts. This contrast underscores the essential role of shade and light in extending daily life and activating public space in tropical environments. By strategically linking lighting posts and trees, infrastructure and nature, light and shadow, the design utilizes existing streetlights as its primary structural framework. Rather than introducing new foundations or permanent construction, the project minimizes material consumption and proposes an alternative architectural model that transforms infrastructure into a spatial and social catalyst for civic life.
Throughout the day, the project generates a dynamic and evolving atmosphere. In daylight, it appears as a rainbow- or waterfall-like architectural installation that captures natural phenomena, casting vibrant, colorful shade across the plaza and creating a comfortable semi-outdoor environment for public use. At night, more than 100 meters of Thai fabric, gently curved into pipe-like forms, become beacon-like, amplifying light across the square and reinterpreting everyday urban lighting as a symbol of collective life and civic identity. The pavilion’s angular composition references the roofline of Wat Suthat Thepwararam, while fish-scale ground detailing echoes the temple’s traditional roof tiles, subtly embedding cultural memory within a contemporary architectural expression.
The project proposes a prototype strategy for enhancing urban infrastructure both aesthetically and functionally. It reimagines how millions of lighting posts across Asian cities could be transformed into future public spaces by integrating principles of tropical sustainable architecture. More importantly, it redefines public infrastructure by allowing citizens to directly experience how thoughtful design can elevate everyday urban life. Through the project, architects Jenchieh Hung and Kulthida Songkittipakdee explore the evolving relationship between infrastructure and tropical lifestyles, emphasizing sustainability, active public engagement, and the continued vitality of the city.
