Caterpillar House by Sebastián Irarrázaval

Construction of the 350-square-metre container house took just 8 months compared to a year or more, pointing out one of the many benefits of prefabricated construction. It also cost a 1/3 less. The site was first cleared of loose clay and rocks, and concrete retaining walls were erected to enclose the living areas on the ground level. Outdoor stairs at one end lead up to a side deck, with an open container serving as a cantilevered lap pool. To support the upper level, a massive steel cross­beam and posts anchor the containers that line up in four side-by-side volumes, each with its own viewfinder window at either end. The containers were trucked to the site and then cut and welded before being craned into place. Polyurethane was sprayed on, and the entire structure was clad in steel plates.
