In the city of Shenzhen, a lot of construction waste is left behind because of the city's rapid development. This project uses recyclable wooden pallets as the main construction materials, and explores the sustainability of the materials, also hoping to draw the attention of the design industry to this issue. Thanks to the wheels and the tracks, some wooden partitions in the office are flexible, which gives mobility to the space and could fulfill the future demands of multi-functional office zoning and sunlight adjustment.
