It is a fascinating idea and sees well thought through. The very idea of a architecture grown from the earth is fascinating and Larsson seems to have thought it through.
Sand/Stone | BLDGBLOG – A student, Magnus Larsson, at the Architectural Association, has proposed a landscape project that will solidify desert sand into sandstone, thus creating a new material for habitation within a harsh desert. The idea is to use injection piles to 3D print sandstone out of sand by injecting a microbial solution that will solidify the sand into sandstone. These structures can create internal micro-climates more favorable to habitation and the sustaining of life, condensation of water and the locking of the sand dunes which could potentially halt the progression of the desert.
