A round or square end table big enough to provide useful space for both sofa and loveseat would work, with a large lamp. I have a couple of live plants under a similar mini-split ac unit and also near hear registers and they don’t seem bothered as long as i don’t let them dry out. Some pillows that pull the color from the very pretty rug would be nice, maybe the pink? Or green? Drapery panels can often make the difference between a comfortable room and a cozy room that feels finished IMO. You might want to check out curtains in linen or cotton from Ikea or Target, they’re quite inexpensive and look decent for the money. Mount the rods near the ceiling molding and have the drape just barely touch the floor. You may have to shorten, they make iron on tape that make it easy to hem without needing to sew. A cream color would look nice with your gold-beige walls. Mount the rods wide enough to push the drapes back off the glass for maximum light and views when they’re open. You may never need to close them as you have blind for light and privacy control. hope this helps.

Hi, you have a nice space to start your projects. Do you need the built-ins? In the photo it looks like they are interfering with your electric heat, your air conditioning unit and they seem a bit flimsy and busy. If you don't have a large book collection, I would take them down. I would look at medium toned wood look laminates, not too busy. You have to choose something that won't clash with your tile and with your different wood tones - trim, the beams and kitchen cabinets wood tones. Definitely bring home samples to look at in you light and space. All neutrals have undertones and the undertones can clash.

Here are some guidelines for dining rugs. If you're handy with refinishing, it may be worth it to refinish your table. IMO pedestal tables are nice in many scenarios. Medium brown is a versatile wood tone. It will give you some contrast with your lighter more yellow floor and looks good with blue. Before you rush out and buy anything, start putting idea books together and try to understand what you like about the different photos and how it would work in your space. Window shopping and trying out chairs for comfort is helpful. Dining chairs vary in seat height and depth, and you want it to be a good height for your table - tables sometimes vary a bit. Our dining table is an antique and is a little higher than average so we had to find chairs that were higher.
