In 2019, ArchSD participated in the Beijing Expo together with our building, the Hong Kong Garden. With a theme of ‘Hong Kong – The City of Contrast’, the garden juxtaposes two contrasting conditions: the representation of urban fabric and hyper dense condition in Hong Kong. This raises the awareness about urban greening. Hong Kong Garden is composed of three components: the Horticultural Garden, the Architectural Pavilion, and the Artistic Feature Wall.
