Sustainable street food

Rain Catcher merges a Hong Kong street tradition with environmental sustainability to create a surprising outdoor eatery that reuses monsoon rain.


15:15 Rain Catcher by YS Groundwork is the result of a competition entry for the contemporary design of one of Hong Kong’s oldest urban traditions: the Hawker Stall – Dai Pai Dong. A Hawker Stall is a kitchen, a dining room and a living room – a space for passersby to enjoy public space, interact with strangers, and grab a bite to eat on their way to their next destination. Initially exhibited at the 2009 Hong Kong Shenzhen Bi-City Biennale of Urbanism and Architecture, YS Groundwork has won the opportunity to bring their design to life and prove that their twist on tradition will add vitality and innovation to Hong Kong’s street life.

YS Groundwork is supported by and collaborates with Hong Kong Polytechnic University’s Department of Electronic Engineering. Their aim is to enhance architecture with the latest energy technologies and 15:15 Rain Catcher is a result of this partnership. The innovative stand featured an additional element to the stall; the formal design – that of an inverted umbrella – was devised in order to collect and store rainwater. Inspired by the monsoon climate of Hong Kong and Shenzhen, the design was chosen to celebrate rain.

The rainwater is collected through the PVC roof and directed to a central column to create a load-bearing structure. It is then filtered and redirected to a water tap where it can be reused for cooking and washing. In this sense, the rain, which can be a burden to the city, is used to celebrate an aspect of Hong Kong cultural city life where food and shopping can be enjoyed.
