Think first about how you will use the space...how big is your household? Are you single or have a child and need play space? Do you entertain? If so, is it big parties or maybe just a couple of people? Will you need the LR to be sleep over space too? Do you need a formal eat-in area? Or would a convertible sofa table do for the few occasions that you'd need it and you eat most of your meals on the couch (as I do). Do you watch TV a lot? Do you want to see it from the kitchen too? Do you need a reading corner? A desk area? Will you need extra storage or do you live more minimally? Will each bedroom be a bedroom or will one be a potential study/craft room/guest room... Function first, then you can decide how to furnish the space to fit your needs.

I'm not sure how to rearrange the furniture. Unfortunately, this room is our only TV room so we somewhat arranged the furniture to be functional. Ideally, I think the room would look better with 2 sofas facing each other with the shelving unit in the middle of the wall and perhaps a table by the windows but it would be too uncomfortable to watch TV sideways. The room is fairly large so I tried to fill it the best I could. I actually pulled the rug out from underneath the couches so as for it to be closer to the corner sofa couch to include it. If I move the corner couch closer to the couches, it floats in the middle of the room? As for the bench under the window, we use it daily!! The bench by the stairway was an extra that does not have a functional use but rather space filling features:-)

Have you considered a back to back sofa arrangement? Float your two sofas back to back in the center of the room so each has a similar sized area in front of it. Give each of them a coffee table. Maybe that small clover leaf table can serve as one. They usually arrive 1" above or below the sofa seat. Try the demi-lune one in your foyer. Put your hi-boy desk in the center of the back wall and hang a knock out piece of art above it. Flank it with a pair of chairs, each with its own table and a new lamp. Your floor lamp is a bit small and the table lamp too tall. Move your bar stools to a bar area, perhaps in the kitchen. Add one more chair to the foyer end of the space. Here are some helpful charts for the details.

Yep a to scale plan all measurements clearly marked is the only way to get help. Also a bit more info like is there a TV going in the space , how many seats do you need in the LR and the DR What is your style. That flooring is going to drive the bus so we need that marked to scale on your floor plan too.
