A 'Waterfall' in Bangkok

As part of Bangkok Design Week, which took place in early February, Jenchieh Hung and Kulthida Songkittipakdee of HAS design and research designed High Line Bangkok, a temporary pavilion that “reinterprets public infrastructure for tropical living.” Here we present some photos and drawings of the pavilion.
High Line Bangkok was situated at Bangkok City Hall Square in the heart of the city's Phra Nakhon district, in front of the Bangkok Metropolitan Administration City Hall. (Photo: DOF Sky|Ground)
The public space hosted previous installations, including MVRDV's Mega Mat installation for the 2025 Bangkok Design Week, but HAS design and research extended the pavilion into the vertical realm. (Photo: DOF Sky|Ground)
The “waterfall-like” installation was made from more than 100 meters of Thai fabric stretching from the streetlight to the plaza. (Photo: DOF Sky|Ground)
The curve of the fabric was meant to echo the angle of the Thai temple Wat Suthat Thepwararam. (Photo: DOF Sky|Ground)
The repetition of linear elements is reminiscent of HAS design and research's Museum of Modern Aluminum, which we featured in 2023. (Photo: DOF Sky|Ground)
The architects contend that the material choice makes this year's Bangkok Design Week pavilion zero-waste. (Photo: DOF Sky|Ground)

The pavilion was conceptualized as a shade canopy that could be implemented across Bangkok. (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
The concept diagrams show the public square as it exists… (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
…then with the streetlight turning into a “tree”… (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
…then starting to form a “new city green space”… (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
…and finding its final form. (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
“During periods of intense daytime heat,” the architects write, “people naturally gather in shaded areas beneath large trees.” (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
The fabric had the effect of increasing the amount of shaded areas within Bangkok City Hall Square. (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
HAS design and research envisioned various activities taking place in the new found shade, from yoga and playgrounds… (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
…to lectures, musical performances, and even elections. (Drawing: Jenchieh Hung + Kulthida Songkittipakdee / HAS design and research)
