With population still on the rise and cities not getting any bigger to accommodate the masses, compact homes are becoming more and more in demand; enter the 3M futureLab 2014 project. Peter Ebner, an architect and professor born in Hallwang, Austria, and based in Munich, Germany, challenged his students to build a tiny, easily transportable 3D printed apartment. Through the 3M futureLab 2014 project, they came up with a life-sized sand castles, of sorts.
Constructed using a mixture of sand and glue, the 3M futureLab 2014 project saw that not only is the 50 square feet home 3D printed, but also the thermal insulation, electricity, heating water, and sewage systems. It boasts a bed, kitchen, and bathroom (that comes complete with a foldable toilet). It is meant to target 25-35 year olds.
