How to do the main stairs as a sitting room. Turn fireplace 90 degrees so that opening to living room is on perpendicular (back) wall. Stairs can wind behind fireplace as such, obscuring view and keeping room with one-story feeling.
I love the wood storage under The fireplace, with its raised hearth, takes center stage in the dining room and can be enjoyed from the whole first floor. A small door to the left opens to the outdoors, making it easy to restock the woodpile.
