I think your inclination toward rustic and distressed pieces is the right way to go. Consider a movable coffee table - I see 2 recliners that may necessitate some table shifting?- an area rug large enough to incorporate all the seating, rather than just a hearth rug, and enclosed storage for your electronics. If you can post shots of the room, other Houzers may have some more ideas.

HI -- Well this is a nice floor plan but it creates problems . Because the space is all open doesn't mean you have to put the living room or the dining room where indicated on the plan . Also where you have marked for the sofa is not going to work there . Not enough room and in the way of getting to the bathroom etc, I do think you may have to have a free floating TV stand between the living -dining rooms . You could have the TV on the wall beside the kitchen and have the sofa facing or on the left wall and the dining at the front . I would put the TV on the left wall near the entrance and have the sofa facing it , leaving a hallway walking space behind the sofa . It's too bad the front entrance is on the left . If it had been on the right then that would be better flow into the center of the main floor . If you do decide to have the TV room divider where you show on the plan , keep it right over to the left wall as a room divider , then it won't cut the room in half so much and it keeps the stairwell open . Remember , you do not need to push the furniture against the walls .

Either go with a darker shade for your woodwork or a lighter shade for the woodwork than the wall colors. I would use either the same color for all rooms or at least within the same color family. Each room will look different if you paint them all the same anyway due to light, time, of day and your furnishings. I like to choose the very lightest shade on a particular color spectrum. In other word a white with a hint of color. The ceilings do with a soft white or an off white. If you plan to place the TV above the fireplace a darker color will look good as an accent on that wall. If you have a narrow room try a darker color on the smallest wall to balance the size of the room. If your rooms are large try a very dark brown or navy or maroon as an accent wall. Have fun painting. Remember, if you don't like it, it's just paint and paint is cheap.

I would take away those top arches and have builtins either side of fireplace, have the tv placed on a shelf on the built in, like in the pics, you don't have to have it above the fireplace, if room is small it will feel like it's coming at you lol. Panel above fireplace and hang some artwork or a nice mirror. Quiet like the builtins with the back wall painted
