Prefab Primer

There is no single definition of prefab. In fact, one could argue that almost every house built today has elements of prefabrication, since components such as roof trusses and windows are built off-site. Prefab can perhaps be best understood as a continuum with several points along a path—from a unique, custom-designed, stick-built home at one extreme to a complete factory-built house delivered on-site as a single unit.
