Lean Manufacturing in the Construction Industry [the broken link was removed] by Eric Sander:
In a radical departure from construction on site, Bensonwood Homes of Walpole, New Hampshire, has begun assembling major wall and floor components of their custom homes in their shop. These sections are delivered and assembled on site to reduce the construction time and improve quality. This approach is common in Japan. Toyota Homes and Misawa Home prefabricate custom homes in their factory for onsite assembly. Tedd Benson has recognized the advantage of this approach and is attempting a new approach for custom homes in the US.
