Do you want to purchase anything for the room, or work with what you have?

I think window treatments/fabric ones would help, and perhaps a rug with pattern, if you are planning on buying anything.

I would definitely purchase things for the room. And there are 2 ceiling lights/fans (you can only see one).

I am slightly confused by the dining area behind the sofa. Do you use it to eat on? If not, I'd get rid of it, it doesn't feel like it belongs there.

What is the purpose/use of the table and chairs? Do you eat meals there? Is it important that TV viewing be available from there?

I too am distracted by all the stuff. I understand about the dog crate, but what about all the other pieces in the room? By pieces, I mean anything a normal person can pick up. For example, in picture #4: almost everything there seems superfluous.

Pretty house, by the way.

Agreed. The room works as a family room too, so my kids things start taking over. I can get rid of the craft cart. I can place the bin of blankets in the closet....Sort of tidy up & get rid of some kids things. I'm I can also add curtains, but I would want them almost to be a statement piece.

In a room that size with so much going on, you really don't want the curtains to make a statement. It would be better choose curtains that make the room look cohesive and finished. For people that read my posts often, at the risk of sounding like a broken record, I would do a solid curtain in a textured linen type weave.

A patterned rug would be a good way to add some pizazz to the room. It will define and ground the main living area. A kilim or Oriental rug would look great with your things.

What about if you slide your game table (?) into that back corner and then shift the furniture up where you'd like it to be? A sectional can be tricky, but I think you're right to want things up closer together and to the TV... Plus, if that's kid space, it could be hidden behind the couch a bit.

What a great space to work with! Here are my two things of concern.......no overhead lighting....use lamps only. Next, remove those blinds and use grommet top panels on decorative rods. They can be easily opened and closed if needed. Panels can be purchased in hundreds of patterns, fabrics, and prices. I would get washable ones due to dogs and kids.

Your room is large, but it also has a lot of traffic paths through it. Traffic paths are like invisible hallways, and shouldn't be blocked by furniture. They need to be at least 3 feet wide.

Can you do a quick paper sketch of your room, showing the doorways and entrances to it, and the lengths of each wall and door/window?

With a sketch of your room, with the traffic paths drawn in, you will be able to see the true size of the areas that should have furniture in them.

Let's start with the essential pieces and then see what furniture can come back in. Move the game table to the wall where you have the dog bowls to get it out of the way of the door.

Try flipping the sectional so the longer leg faces the TV and the short leg creates a path between it and the game table in its new position. Put the arm chair by the wall in front of the dog crate, angled to face the TV. You can put the white end table between it and the sofa for now, but it really is too tall, You should replace it with something just shorter than the sofa and chair arms. If there's room, put the slipper chair next to the white chair, between it and the door.

Any piece of furniture that doesn't serve a purpose needs to exit from this room.

@groveraxle, it looks to me as if both sides of the sectional are the same length. I like your idea.

I couldn't move your sofa, but I could remove the game table, hang curtains, properly size your end table, and move your art.

Partim, I believe you're right about the sectional.
