Many buildings in Europe, such as Stefano Boeri’s Vertical Forest, are celebrated as setting an example for a new way of greening up our cities. Recently, Boijmans Museum’s Art Depot in Rotterdam, designed by MVRDV, was completed and featured a birch forest on the rooftop. In Dusseldorf, Ingenhoven Architects designed a building whose facade is basically a stunning hornbeam hedge. For many decades in Singapore, WOHA studio has been creating architecture with green facades and urban farms of tried and tested efficiency. In Vietnam, Vo Trong Nghia Co. Ltd. have popularized the use of bamboo as a building material.
