The French architecture firm Multipod Studio recently unveiled the prototype for a customizable home made from stackable blocks. They call it the ‘PopUp House’, because it can be designed, ordered, and built in less than a month. This is an example of the growing sustainable architecture movement called passive construction. Their ideal is to create homes that are well-designed, easy to build, low-cost, and energy-efficient. The PopUp House, which can be ordered online, costs between €1,000 and €1,500 per square meter, depending on the quality of the materials and amenities. Once a home is ordered, the firm sends along building instructions and a construction team.

The company says that, "A PopUp House can be customized however you wish it to be: as a small and cosy country lodge, an urban two-story house, or a spacious open office." The construction process is a lot like building with Legos (the famous toy building blocks). Each house is made from stacked recyclable wooden panels and insulation blocks, that are held together with wood screws. A construction team can build it in less than a week with only an electric screwdriver... and it can be disassembled just as quickly. The prototype measures 180 square metres and features an open layout with a kitchen and dining area, plus a terrace connected to the living room. It also includes two bathrooms, an office, master bedroom, and two smaller bedrooms. Currently, the PopUp House is only available in France, but the company plans to expand to the UK and the US.
