I am using the Google translator, so do not be angry with me too if you can not understand everything ...

I tried to make the internal dimensions of the house similar to the external,
I added the bathroom,
I deleted the upper chamber (useless, in my opinion),
I added another exit,
outside I connected the second exit with the entry of Megaton with a suspension bridge.

Hope you like it ...
