"How are we to live with the desert, in the desert, within the desert?” asked Swedish architect Magnus Larsson for his new project that creates a 6,000 kilometer-long green sandstone wall in the Saharan desert. By introducing a bacterial microorganism to the desert sand, Larsson envisions the formation of a porous structure that will provide habitable spaces to thousands of refugees. Bacillus pasteurii, commonly found in marshes and wetlands, reacts with sand particles to transform loose sand into sturdy dunes that can support life and living.

The project redefines the limits of designing the built environment, and successfully manipulates the existing earth for a good cause. Realizing his project's pioneering potential, Larsson says, "To really appreciate architecture, you may even need to don a white coat."
