Ok, wasn't gone that long. In the meantime, could you put your sofa on angle toward the tv? Just line it up with the rug. Take your leather chair and place it along the short side of the rug next to the window. If your small table will fit in the corner of the sofa and chair that would be a good place for it. Oh, and if what I think I'm seeing next to the tv(stacked suitcases) you could put those in that corner instead. The decorative key might look good above the cut out to the kitchen...hung long ways. Take down the art print on the wall next to the cutout and arrange a collection of your photos. Try not to go hang any higher than the the print currently is and have the bottom of your last frame hit below the height of the bottom of the cutout. I know this isn't what you were asking for, but while you're planning room layout and the more permanent direction you want to go in...there is no reason you can't try something different with what you have right now.

When you walk into our house this room is to your left and the dining room is to your right. It is also connected to our family room, which is where we have our comfy couches, ottoman, fireplace and TV. This is the only room for a playroom. It is the perfect location because I can see my 3 and 1 year old from almost anywhere in the house. I agree, the chairs are not my favorite. They were a garage sale find. They are a lovely pale blue. I added the slip covers to change the color, but keep the cost down. My kids are not hard on furniture. In general, we try to buy higher quality so it last. This room as always been an after thought. We have 4 kids under the age of 8 and have moved to this house 6 years ago. It has been a busy season in our life, but now that our youngest is 2..we are ready to finish our house.

Why not switch the couch and the children's storage unit. That way, people sitting on the couch can enjoy the view. If you have arm chairs in your dining room, try using one pulled into the room slanted across the lower left hand corner of the rug. That allows for a conversation between the person in the chair and those sitting on the couch. As to artwork, take a look at Pinterest for ways to create a gallery wall of children's art or you could use family photographs.

Cute pooch. Is the eighteen feet from the by window to the tv? If so, you could leave six feet between the back of the sofa (centered with the bay window) and the bay window for your play area. Then use the rest of the area for your living room space. If you want to try centering the back of the sofa across from the bay window, then measure the space between the side of the sofa and the wall with the two smaller windows. It may be that you have room there to place your desk/table with metal legs in that spot with its chair sitting in the play area. A tall thin metal lamp with large white shade on it could serve the living room as well as the desk. If not, find another side table/cabinet for that space for that purpose. You could plan a place in the play room for a bed for the family pet. Underneath the bay window, you might want a window seat that doubles as toy storage, preferably with front doors if the children are small. A top lid can pinch little fingers. https://angelarosehome.com/ikea-besta-bench-hack-with-diy-cushion/ Unless you're wanting a wall to wall built in underneath the bay window -- if you're wanting separate pieces of furniture, then on each side of the window seat, you might consider tall shallow cabinets with solid doors at the bottom for some hidden storage) and either open shelves or glass doors above for displaying family photographs and family treasures.
