Living room: I'm thinking of two swivel chairs and the sofa to give you maximum versatility in arranging them. I would try the sofa on the back wall and the two chairs under the window facing the TV on the long wall. One thing to keep in mind when furniture shopping is the scale of the pieces. Men want big hulking pieces of furniture, but smaller scaled pieces without high backs or big arms are going to fit better in the room. As for the dining room area, you say you need seating but is anyone going to really go into that room and just sit? Does anyone regularly play the piano or should you think about getting rid of it? What is your lifestyle, what can you use the space for? Some people would turn it into a library; I would turn it into a home office. Do you do sewing or crafts? Do the kids need a place to do their homework? Start by identifying a function for the room.

Really nice home and property. You could simply remove any central vac system and invest in a Roomba -- that could get rid of one something along one wall and let you square room 1. https://www.google.com/search?q=Roomba&source=univ&tbm=shop&tbo=u&sa=X&ved=2ahUKEwj1l-Ll87bnAhXJSt8KHZjVD0QQsxh6BAgPECs&biw=1366&bih=628#spf=1580785213419 For heating purposes in a large old two story home, being able to close off the stairwell should be the primary concern since heat rises. From personal experience ... if you have a wood stove, you'd be better much served putting it in a larger room or in a room open to multiple rooms. NOT in a small room such as room 3. If you have a wood heater, you could put it either in or in front of your fireplace (with triple wall metal stove pipe lining the chimney for safety). If you don't want to make room 3 your new Foyer/Entry ... but if you want the room 2&3 side of the house to be your front of the house ... another way to use the rooms is worth considering: You have a tiny bathroom very close to the kitchen/eating area. Budget permitting, the best use of room three could well be closing it off from room 2 and creating a new full bath in room 3. That would enable you to square the informal dining room and move the bathroom farther away from the kitchen and dining area. Once you've moved the bathroom, you could recreate the space between kitchen and informal dining with a pass thru kitchen cabinet "wall" that you can walk all the way around. https://www.bhg.com/home-improvement/remodeling/architectural-details/home-design-ideas-room-dividers/?slide=slide_2bf3e1c7-021a-4262-9de6-fd5daf3777a7#slide_2bf3e1c7-021a-4262-9de6-fd5daf3777a7 Keeping only one interior door to enter room 2 from room 3 means you could use room 2 as a bonus room -- usable as a bedroom or as you choose. It also means you can keep that one door to room 2 closed and not fully heat it all the time. You could keep as is or alter or (if not load bearing) remove the wall between dining and informal living room to create a single elongated rectangle shaped "great room" -- kitchen, dining, family room. If you created a pony wall between dining wall and informal living, your wood heater in the fireplace could heat the entire great room area. You could keep as many posts as needed for support in that pony wall and, with a solid back on the informal living room room side, you can put any furnishings you choose by it with the back to the pony wall. You could alter the porch beside room 2 between the window to room 2 and the door to room 1 to create a wider porch there that wraps around the side of room 1 several feet. You could even enclose that area and create a new foyer and make the rest of the porch on the right side of room 2 your front porch. Then in that back corner off the kitchen at a right angle to room 3, remove the shallow/narrow open porch and create a square deck or patio there with a rail around it and steps exiting on the left side toward what would be the back of your home. You might also consider a "green wall" -- row of shrubs -- all across the yard so guests are led to the new foyer on the right side of the home.

The room dimensions are 25' X 16', with the wall that has the fireplace being the longest. We are thinking small seating area near fireplace with accent chairs and a sectional couch and entertainment center for tv on wall next to the fireplace.

Marie13100, I mentioned in the beginning we are in the process of remodeling our kitchen and we needed to move the dining table into our living room temporarily and cover everything from the dust. Lynn G, you’re right. Having to look at the wall would be a bit depressing. The most recent floor plan I posted that had the sectional along the window and long wall would be perfect because we can view directly outside the patio door which is in the dining room.
