Balcony that also supports a roof, on top of a roof?

[Snailman]

Something like this is what I was thinking (for the middle part of the house, that is) http://www.fiskarhedenvillan.se/addition/house/showImagePopup.php?image_id=img_45e3f18389b55

with the difference that I probably want the section of the house under the balcony to be wider than the balcony.

The method shown in these pictures I don't think works due to the columns that are supposed to support the roof:

Anyone know/have suggestions on how to do this?
