These Lego-style classrooms were built in a few weeks with only a screwdriver

It's a problem that Alfred de Vigny and Rollinat - two private high schools in Indre-et-Loire, France - ran into when they wanted to expand their admissions capacity. The schools needed more classrooms, but the cost and time needed to expand the existing buildings was more than they could afford.

The schools instead decided to build two PopUp Houses, customizable structures made from stackable blocks (kind of like Legos), to serve as satellite classroom buildings. Designed by the French architecture firms Multipod Studio and Arc A3 Sud Touraine, the PopUp buildings each took about two weeks to construct. The whole process of designing, ordering, and building happened in four months total, with the second building complete in December 2016.
