From another blog

Right now, I am having trouble because of the rediculous blocks between Blogger and Blogger beta so I am just copying some of the text from this article instead of blogging it.

About the DIY homebuilder market:

To a visitor from the UK, the gleaming efficiency of the production lines is a site to behold. It’s reminiscent of car factories with wall and roof panels moving through assembly lines with a minimum of human intervention. If you want to read up more on it, there is a very funny description on the But She’s a Girl blogsite. Baufritz produce around 250 houses a year with a staff of 260, of which around 80 work in the factory and a further 60 work on site as erection crews. Work it out: it’s roughly one house per person per year. Say 1800 hours input. In the UK, you would expect to see between 3000 and 5000 hours work go into a traditionally-built house of similar size, and not that much less for a timber-frame one.

Pretty cool.

There's more. Read on if you like:
