Extreme Makeover: Home Edition - How'd They Do That?

It really is a great show, Extreme Makeover was good enough but in How'd they do that? you get to see all the trials and tribulations they had to go through to get this project done, I've only seen a few of them but it is really nice to see, especially when you get to see how Ty does his secret rooms. It's good to see that things don't always go to plan like in one I recently watched where it took 3 attempts to pull the house down and another where they had to wait 10 minutes for the family because they were singing "The wheels on the bus." and to put their coats on. It really is a great show because you can see how they did it and if it's simple (though it is EXTREME makeover) you can make it yourself.
