A finished house stands on what just a few days ago was an empty green field. Such a feat is possible thanks to components that are industrially prefabricated in a manufacturing plant for finished parts and then simply need to be assembled on the building site – “prefabricated houses” in other words. The individual wall, ceiling, and roof components are usually made of wood. First, the manufacturers make a frame structure out of squared timber in the plant, onto which they then fit boards made of timber derived materials. Nails and staples hold the structure securely together.
