Vancouver architect Oliver Lang maxed out a commercial lot to create a four-residence prefab tower that takes smart urban planning as seriously as good design. Each of the residences has outdoor space attached to it; the family’s unit has a roof deck. In lieu of a green roof is a galvanized tub filled with grasses—a collaboration between the architects and landscape architecture firm space2place. Photo by Kamil Bialous.
