Shanghai office Four O Nine has converted a glass building in Beijing into a cafe, adding walls of plants to purify polluted air.
Influenced by Cafe 27's organic menu, the team aimed to rework the existing structure into a "healthy" building lined with greenery and natural materials.
"The design was inspired by the client's choice of food for the cafe," architect Lukasz Kos told Dezeen. "All of the food is prepared on site in the cafe pastry kitchen, from healthy organic ingredients."
