Living Blocks are the invention of Lawrence Parent, developed from his degree project at Brighton University. You can make them yourself from  an "open source" (i.e. freely accessible to all) recipe for modifying simple moulds with balloons and discarded fruit and veg. You’ll produce irregular pitted  “planting blocks” that mimic a natural stone, thus  harbouring vegetation and wild life to soften harsh urban landscapes. Lawrence has now set up a design studio called Wild Structures to further develop bio-receptive surfaces for cities. You can explore his research and shop his products as they come on stream. "I have a passion for biodiversity and want to connect humans and nature."
