When it comes to the eco-advantages of prefabricated home building, it truly boils down to one thing: superior efficiency. While factory-built modular homes are more efficient than their site-built counterparts in numerous ways — particularly in the construction waste department — the speediness of the whole process is the most captivating, thanks in part to nifty, time-lapse videos like the one below.

Although I’m not a huge fan of the finished result, the installation of this eco-friendly modular mini-manse in Bethesda, Md. — the Bradley Green Show Home, part of the New Classics collection from Sandy Spring Builders — is mesmerizing to watch (the frantic music certainly helps). Of course, weeks of hard work — 16 weeks from foundation, to be exact — went into the home before and after this well-orchestrated act of Lego-stacking, but that’s not nearly as fun to watch. Have you ever watched a modular home installation in the flesh?
