Prefabricated wooden houses date back to the 19th century, when so-called "kit houses" became popular in North America. Sold by companies like Sears, they offered affordable and convenient housing options, especially for people living in rural areas where labor was scarce and expensive. Customers could choose from a few designs and dimensions, and the kits usually included all the materials needed to build the house, including numbered and precut lumber, nails, shingles, and other necessary components. For some time, however, prefabricated houses were seen as constructions of lesser quality and prestige, and coupled with the lack of flexibility of these solutions, they went into decline.
