What's staying? What's going?

How many people use the space and for what functions? It seems that there are two workspaces (those with the double monitors)? Is that a blackboard on the wall next to the small table? Is that space used for home schooling or dining? It would be helpful if you could sketch the dimensions of the space - walls, doors, windows. You probably are aware of this already, but some serious decluttering will help calm the space and will facilitate other improvements:)

Define the Living Room with an area rug that leaves 3 feet around the perimeter for foot traffic. Place the seating and coffee table on the carpet.

You need larger storage and shelf units than what you have.

There seems to be an overly abundant amount of chairs for this space.

Excellent suggestion to use a rug to define the seating area -- it would be a big 'un, but worth it. I suggest you start your decluttering by taking down the doodads over the arch, and taking a good look at what is on the larger shelf unit to the left of the TV -- it would be good if you could put a lot of the stuff there neatly in shelf boxes -- there are really good-looking boxes available. You could then pack the things you really want to look at on the shelves in an uncrowded way, and still have the other stuff on the shelves for easy access.

Also look to edit smaller items into larger storage in other areas, eg under the window sill. Fewer open shelves, if that's practical for your lifestyle -- I get the feeling you all do a lot of living here. And rehang the family (?) pictures in a tighter format so that they give them impression of one composite thing instead of lots of little things. And bring it down somewhat lower.

Your room is a nice space. I like the architecture and the windows and the paint color looks fresh.

Properly sized rugs are the easiest way to define spaces.

I also noticed that all your wall decor is too high and should be hung people level.

There are no blank wall spaces in the room for the eye to rest and that contributes to a chaotic and not cozy feel.

Hi, it would help a bit to know what your plans are, do you plan to rearrange the furniture you already own or if you plan to purchase new furniture. There is definitely a lot of stuff in this space, I agree with decluttering a bit and using boxes to hide some of your things away. I also agree with getting a larger rug, to define the living room area, I would also think about getting something bigger under the tv a closed unit where you could also put some of your stuff away, not too big, just wider and with doors. In case you are planning on getting some new furniture pieces I suggest getting something less bulky than what you have in it will open up the space.

You got some good ideas on layout above. If you give us a drawing with dimensions, we can give more detailed layout advice. Regarding the cozy factor, especially in fall I like to have a sheepskin rug in front of sofa or fireplace, faux fur or fleece throw blankets, velvet or fur pillows on sofa, candles, floor lamps with Edison bulbs. Haven’t figured out where in the world you live, but here is a throw blanket I love from Amazon. Also, Costco has nice affordable sheepskin rugs - the “quad” which is four skins sewn together is a nice size.

Here is a floor lamp I like. I admit to still using incandescent Edison bulbs, and sitting next to it on a chair or sofa on a dark winter day is next best thing to sitting next to a fire :)

All these ideas are really helpful!!! Thank you!!! We have 6 grown children so our space has flexed and bent over time. It results in multi tasking spaces.

The recliners went, moving things around and purging is happening. The shelving will be built from what's on the left across to the right and around to the window. That will mean the TV will be built in and the black shelves go away. I hope new furniture after that. The corner of where the black bookshelf is will become a built in electric fireplace.

Wow, you are really motivated!!! I hear you about accumulating all the things needed to raise six children, and probably you want to keep some of those things for grandchildren who visit. Impressive feat to launch six children into the world! A few things to think about: those of us who own a home with a corner fireplace find decorating around them challenging. If you could build in a linear fireplace under your TV, that would combine the two focal points. I will include some photos. If you put doors on the lowers of your built-ins, it would reduce visual clutter. And if you painted your built-ins a dark color, it would also help everything on that wall blend in better. Also, if you could find two really large art pieces, 4’ x 6’ or larger, one for over your sofa where the gallery is, and one for the dining room where the blackboard is, it would dramatically improve the look. You could shop for canvas pieces on a website such as Great Big Canvas.com. Or you could do a textile wall hanging such as a Suzani. Maybe the gallery photos could be relocated to a hallway or bedroom.

Kind of like this:

But with a more linear fireplace that is as wide as the TV like this:
