One thing to keep in mind: As impressive as this is, it's misleading to say that it's just a two-day project. Consider all the work not captured on video: It took a full two months to fabricate the pieces in a factory. And even after constructing the shell, the building isn't done: there are still windows and other parts that need to be added on. As for cost, officials told The Times Of India, "The cost is almost the same as of conventional construction material. It saves a lot of time that goes into construction otherwise."
