First floor

Wow, that's big! You could use an wide archway to divide the spaces if you think it needs it. Loving the floor

That's something to think about for sure, thanks for the thought @chapchap73. 

You could make it side opening ;)

I was thinking of a moving panel on (mini) wheels between the two rooms. I guess that used to be a thing in Tudor times. Like a room divider screen only made of wood. Once I get furniture in there though I'm sure it won't be so cavernous looking.
