Thanks so much! Valinsv, I had thought about doing Roman shades, and I think that would look great, but...I'm afraid the hardware/mounting wouldn't stand up to the raising and lowering of the shades. I think my fastest/cheapest/most sturdy bet is to hang them flat, like Palimpsest suggested. Les, I would love to add casings, but that would be low, low, low down on the list. After the fence, gutters, other misc. repairs, etc. These particular windows weren't installed properly. They don't open and close like they should, and they're drafty. We're going to caulk around them as best we can until we get to the point where we can replace them. If I had my way, we'd replace the whole bay altogether and turn it into a traditiona, flat window, but I imagine that's cost prohibitive. That room originally was the garage, so I have no idea what, if any insulation is in the walls. Adding insulation is also on the to-do list.

I have nearly exactly the same layout, except add a door in the upper left corner and replace your bottom wall with wall, wide opening, closet. My room is also longer than yours - it's 18'x18'. I have added Billy bookcases with the half doors and height extensions to either side of the fireplace. It looks good and the extra storage is a godsend. I would definitely integrate a desk into any built-ins you do, like the picture kellyeng posted. Obviously custom built-ins/bookshelves are nicest, but the Billys are fine if you are on a budget. You could buy the short ones and/or cut the Billys down to fit on top of the desk. I have found two layouts that work for my room. Obviously we have different furniture but perhaps reading this will help you. 1) float sofa in front of fireplace, put sofa table with lamp(s) behind sofa, put two upholstered/leather large chairs in front of left window, float loveseat in front of slider on right, put coffee table in front of sofa, place dresser for extra storage on bottom right wall. 2) Float sofa and loveseat in the middle of the room perpendicular to fireplace with coffee table between them. Put the two large chairs south of the sofa & loveseat, angled toward fireplace. Put dresser for extra storage on bottom right wall. My TV is above the fireplace since DH wants it there, but you can easily put yours in the upper corner since you have less furniture. I would recommend that, actually, since the closer you are to the TV the less comfortable it is to look up that high. You really just have to move things around until you are happy - at least for now. The room is awkward, no doubt about it. So, when I get sick of one layout I switch back to the other. I switched back to my Option 2 yesterday. DH laughs at me but hey, moving furniture is cheaper than moving.

Here is just one example. This is the lazy boy Duo Ryder reclining sofa. Clean lines. Back remains straight when you recline. So, it is a wall-hugger or incliner. Keep in mind, for this particular one, it does not recline fully. Slight recline and foot rest rises. Other models I mentioned have a much greater recline. Depends on your budget, style, and what you want functionally in a recliner. Many now have usb ports in the recline button. You can see it one the side of the chair below. Also, consider a battery pack. Finally, some have an articulating headrest. The Duo Ryder does not, as it does not recline much. The articulating head rest allows your head to be pushed forward to view tv/read (when you are reclined). Do your research. As others have mentioned, be cautious about sectionals. No one wants to sit in the corner. Adults who aren't couples prefer an individual seat. Finally, unless you buy a modular sectional, you are committed to that arrangement for the life of the sectional. They are for some people, but not for all. Here is a floor plan for you. With the base heaters, you will have to float furniture. I recommend a reclining sofa and 2 chairs like this. This is a to-scale 10 x 19 room. Not sure of opening and window measurements, but they are approximate. Let me know if I can help any further.

The first thing I would suggest, since you have a toddler, is to replace the coffee table with an ottoman style. And one with storage might also come in handy. https://www.wayfair.com/furniture/pdp/winston-porter-hovhan-24-wide-faux-leather-round-storage-ottoman-w002595324.html?categoryid=46573&placement=1&slot=5&sponsoredid=d4e8e5619ab9a606a14d2e0d13184a826f498fe45f01ed3877af4de3a6d8b16f&_txid=I%2FWEwmDAm6WY5kafqjzkAg%3D%3D&isB2b=0&auctionId=68b3c18e-df0b-4b4e-a646-79348ea53252 I think your instincts are good as far as sofa placement - w/ sofa facing door area. I would not want to place the sofa right in front of the door - but would there be room to slide sofa down a bit so that it is more centered on the wall, without the sofa being in direct path of front door? If so, I would slide sofa down a bit and put tv in the corner. You could even just use a shelf console there. https://www.wayfair.com/furniture/pdp/ebern-designs-french-tv-stand-for-tvs-up-to-50-w005062826.html?piid%5B0%5D=625389365 ETA: With that arrangement, you should have room to add a chair facing the window; and maybe a streamlined recliner could work for you there. A bunch of colors on this one. Here are just a few.
