The theme of the Garden is City of Contrast, it represents Hong Kong in Beijing Horticultural Exposition 2019 with the juxtaposition of two contrasting conditions of the city: a hyper dense urban fabric and a serene agricultural environment. The design aims to explore the relationship between urban and garden, and the aesthetic value of edible plants. It invites visitors to re-imagine the notion and possibility of sustainable planting in hyper-dense environment and it deploys layers of urban fragments that resembles a cohesive form of impressionable memory of this compact city.
