Are the rattan chairs comfortable? Could you put both of them on the same side (the fireplace side) and put one leather chair with its back by the door? In terms of a coffee table with book storage, my sense is that it might clutter the center of your narrow room. You might do better replacing the side table by your couch with something that gives you book storage. I would also like to see a taller lamp on that table (or could you just get a taller harp?) Given that you have small kids, an ottoman (or two) that is lightweight and movable might be handy. By the leather chair, a floor lamp with a tray table would be nice. As far as the DR side of the room goes, it seems to call out for some color. The drapes, table and cushions are all neutral. You could add color with artwork or a ceramic pot or . . . Good luck, it is a lovely space.

I grew up in a family of nine. Most of the time we lived in military housing, which was assigned based on rank, not the size of the family. At one point, we lived in a 3 bedroom, one bathroom house, with a galley kitchen and a combination living/dining room, with a tiny pantry/utility room off the kitchen for the washer and dryer. No attic or basement. The age range of us kids was newborn to 12. The master bedroom had two sets of bunk beds and the 4 oldest boys slept in there. Mom and Dad had the next biggest room, with the current baby. My sister and I had the smallest room, which was a bit cramped with a crib and a twin sized bed. As for getting ready in the morning, we had a shower schedule, with some of us showering at night and others in the morning. (In part because no water heater was going to be able to provide enough hot water for 7-8 showers in a row.) I know that there wasn't much extra room, but my memories of that house don't include any idea that it was too small for us (I estimate that it was about 1,750 sq. ft.). Mostly, it was the 1960s and we just didn't have a lot of stuff. Otherwise, we'd have been hurting. My suggestion is to declutter stuff before the move. Then declutter again. In a small space, it is difficult to hold on to stuff that you aren't using right now. So clothes you are saving for the next kid to grow into, toys that aren't being used right now, but a younger kid might want in 2 years--consider letting those go. You'll have to pay to move them and then you will have to find storage space for them, unless they can be stored in one of the outbuildings. Be flexible in how you look at your new space. That porch room, since it is heated, could become a playroom. Or an office. The kids are getting to the age of homework--maybe you will need to fit desks into their rooms instead of the dressers. Could one of the outbuildings be set up as a play space, at least for the older kids, for at least some of the year? If at all possible, I'd move there with your current furniture and live in the space for a few months before making any big changes. You need to see how you really use the space to know what furniture you will want to let go and what new furniture you will want to replace it with. My parents always ended up making a shopping trip after we'd been in a new house for three months, to buy the things that would make living there easier--a kitchen cart in one house, storage cabinets in another, a smaller coffee table or kitchen table. (Just so you don't think the military kept us in inadequate quarters all the time, a few years and houses later, we moved into a 6 bedroom, 3 bath house with two pantries, a music room, a 3 season porch, parquet floors, window seats, french doors leading from the living and dining rooms onto a lovely front porch, basement and attic with tons of built-in closets and cabinets, a room for the maid (which they must have had in 1850 when the house was built) and a tunnel connecting the house to the garage, the former stable, so the occupants could get to their transportation without getting cold or wet. That was military housing on a tiny little base in Philadelphia. )

My living room is 17 1/2 x 15 1/2 I don't find it too large for a single seating area. I guess it depends on how you lay out the furniture. Where your TV is we have a fireplace with book shelves. The TV is in the book shelves with 2 chairs flanking the fireplace. I have my couch where you have your love seat and my love seat where you have you couch. Maybe switch your love seat and couch. This would push back the room and fill up the empty space.

I love that you are using your family rug in the space. I don't think white leather furniture will do it justice though. Too harsh a contrast. My first thought too was to turn the rug so the longest side runs with the fireplace. It should be centered in the room either way. That is the first step. That will help make the fireplace the focus of the room and bring the seating closer for conversation and tv viewing. There should be 1'-1.5' of wood flooring showing around it. Pull it right up to the legs of the piano so the bench is on it protecting the floors when you move it. 2 couches work but I think people prefer to have a couple chairs instead of sharing a second couch. If you get swivel ones you can move them to watch tv, join a conversation or enjoy the view outside. Get some of those furniture sliders to help you move things, they really work. If you keep 2 chairs with a table between by the windows I would just get a sofa table to place behind the couch so you can walk into the room from both sides of the couch. I would play with the furniture you have now and get the arrangement down before looking for new furniture.
