If you are going to build a raised bed for your vegetable garden I have always like this design versus a rectangle.... Or some portion of it....

There would be enough space on that wall. My concerns were placing the sofa against the windows. Since the windows are very low (Down to about 1' to the ground), a 37" high sofa would block 2 feet of window height. Depending on how far into the room the sofa is, that would take 2' off of 2-4 windows. (The window location in the render is not 100% accurate, but if you look at the picture, it'll likely cover all 4 windows) In addition, those windows go to the backyard, which we would get afternoon & evening sun from. We were concerned about having a lot of glare from the sun if we put the TV opposite of the windows.

Floating the bed is a nice idea but you wouldn't have room for any type of night stands. An armoire is a wonderful idea for extra storage. Something like this with some extra drawers would work. https://www.overstock.com/Home-Garden/Grain-Wood-Furniture-Greenport-2-Door-Armoire/25739333/product.html?option=43173892 Then use bachelor chests or 3 drawer nightstands for more drawer storage. https://www.wayfair.com/furniture/pdp/rosalind-wheeler-lusia-3-drawer-nightstand-w001460587.html If there's room, perhaps you could add a bench under the window. Just simple white sheers on the window since you don't seem to need privacy. The floors are beautiful and it's a lovely room. A modern antique brass bed like this would make a wonderful juxtaposition in a traditional room! https://www.burkedecor.com/products/westwood-bed-in-antique-brass?

I can't judge the spacing from your photos. if you did a sofa like this under the front window, had the tv over the fp, or, even have it mounted to that opposite wall w/a slender console under it, a few comfy chairs like shown, would this work? ignore the built ins. Look at Article for leather sofa. I have their Sven in the black leather and it's really nice. comes in diff leather colors, and different velvet or fabric options this one is mine w/their bench and walnut chair, leather pouf, and I refinished the vintage Brasilia console. Both of the art pieces are collectable prints from known artists/photographers. I like the idea of doing a walnut console on that one wall across from FP. whether or not you mount a tv or art is up to you. if you do some art, then get something this size. you say you have your plants, use them! you have a great spot by the front window. I have a fiddle leaf in my other room and that thing won't stop growing. it's so tall and huge, it's a good thing I have vaulted ceilings! IF you do the sofas that face each other, you can still put the tv on that wall, and do art over the fireplace. You see how they have the space over by the window? I don't know how much you would have, but you could set it up like this^. IF you have more room over there, do a small side table, two small chairs, some plants, and have a little sitting spot. or set up a little play area w/a bench under the window to hide toys.
