Interior of the Madison

Hi, I've ordered my first dollhouse kit and it is the Madison. Until now I wasn't able to find any pictures of the interior of the shell. I would like to know is the support in the attic optional. I was planing on using the attic in my madison as a little bedroom. The whole house is going to be a fairy's cabin in the woods! Did you also take out the wall on the first floor and if you did, what was it's position? Any information at all about the Madison would be very helpful!

Thank you.

P.S. I love the siding by the fridge, by the way.
