Does your cute toddler play with all of his toys, all the time? Might be more interesting for him if you would put some away and in time swap for the others....they will seem "new" to him again.... Can you get a low storage bench for in front of the window and keep his toys corralled there? Something he can open up to get to his toys...Have only one couch and get a couple of swivel or recliners for your space. If possible, I would hang the TV on the wall...I see a pen around your TV now....Just remember the toddler age lasts for a couple of years and then it will pass. I had a climber also and had to listen for the squeak of chairs as he pushed them over to the bookcase and what-not shelf to climb on. Another idea, could you have the dining room his designated toy/play area and you have a small dining table in your living room where the toys are now?

Your plan looks good, but don't do a custom sectional unless you plan to live here forever. Maybe not even then. Have the sectional end where the kitchen begins. And I wouldn't use Barcelona chairs there. I love the way they look, but I wouldn't want to watch TV from them. Also consider a standard sofa instead of a sectional, and then where you show the chaise you could have an Eames lounger. Now that I would watch TV from.

You guys are a bunch of geniuses. My key take aways: make Beverley’s adjustment to the couches; consider the parallel option again move the tripod lamp to the other side for balance consider adding second identical coffee table or look for similar square one lose the awkward slip chair spot and follow groveraxle’s good ideas above art not mirror above the couch. One large piece, keep it simple, maybe something along the lines of these ideas:

I agree, centered in the middle of the living room, and If you can get a tabletop TV on a swivel stand or a wall mount swivel, you can watch if from the dining room, kinda, or living room. The middle of our 64" TV is at 48" from the floor but could be a tad higher. Please don't mount way high like people do nowadays, ouch. That means you can place the sofa facing the TV with the back of it defining an entry hall and a coffee table in front of it with two side chairs facing each other or at an angle toward the TV Or place the sofa on the window wall, watch TV prone (hello!) with coffee table and side chairs in front of it. We even got a swivel side chair...get two...so convenient for this configuration. Place your entry console, with table lamp and mirror on the wall above it, on the kitchen wall facing the door. It will the first focal point when you enter and reflect light from the window. Your sofa end table and lamp will be next to the front door in any event, don't worry, ours is and it's fine like that. Got any other furniture? A tall bookcase on the shared wall centered on the console wall. Buffet in the DR. Kitchen wall.
