Stormwater Planter Box is an innovative approach to urban green space design that integrates environmental, economic, and social functions in a sustainable manner. It aims to address key urban challenges, including flooding, water pollution, and the lack of green space. The planter box is specifically designed for Bangkok's context, capable of absorbing and filtering rainwater before releasing it into the drainage system. This helps reduce the burden on urban drainage infrastructure, increases green space, and enhances the overall quality of life for city residents in a sustainable way.
