Here are some ideas for your space: (your living room has so much space!..)

-Get an area rug 3 to 4 times bigger and place in center of room.

-Pull couches off the walls, two seater with back to diamond art wall and the three seater opposite it/facing it with coffee table in the middle of them.

-Flank the back of your three seater with a credenza type slim table with a table lamp on it.

-There are not alot of accessories in this room, so you can buy any area rug you like and pull from it's colours to buy ie. accent pillows(also with interesting texture), or art...Perhaps to be safe, be sure your wall colour is in it somewhere too.

-Get a drum shade for your lamp that is either white to cream in colour

-Your curtains need to be about 3 inches longer and touch/skirt the floor. Get a white shade or cream shade and push curtains so that they frame the window. You could also get white or cream curtains that are opaque to close in the evenings and push out of the way during the day.

-Square off/straighten your diamond into a square and put a piece of furniture with drawers underneath it against the wall that is at least four half feet tall.

Example of a carpet for your space by a company called nuLoom.

- On the left side of this picture, you would also have space then to put two armchairs or cool chairs to complement the setting.

-Also beautiful would be really nice complementary light sconces on the empty secitions of wall on the diamond art side.

-lastly, I cannot see it, but it looks like you need some kind of storage system for speakers and other...

My two cents worth.

I agree. We need two chairs.
My tv unit is on the right that’s not seen in pic. And there’s a multi system unit from where the pic is being taken. I need to decorate / arrange that too. But that’s a another discussion:)
When kids were younger we had deliberately kept an open plan for them to have room to play.
I do like sense of open space.
Will move furniture and try credenza kind of thing. Only issue is then seating is less practical as tv is on the right.

Yes , I need to change curtains as well. And add chairs. Will look into it.

Your space needs a very large rug to make it look right. It's easy to go too small but it's hardly ever possible to go too large. I don't think kids mind playing on a warm rug instead of the floor from what I've seen.

Annouk33,
Love your input. Need more help.
Both my sofas are three sweaters as I needed more seating.
If I put them in middle of room, Wont i lose space behind them. Also, what do I put behind them - lamps?
Will the room seem too full and busy ?
If I put a furniture / table under diamond art( it’s a set of hand painted tiles ) then sofa will cover it.
It’s a square room leading into dining on one side and kitchen on other , backyard on third.
Thanks in advance for all help :)

Manhattan home - I am unable to see your suggestions

Sorry. Got it now

How about this one?

With only the one view, I would recommend that you center the sofa between the two windows and start your furnishings arrangement from that point. You need a much larger rug and larger coffee table. Twice as many panels for draperies on the rods to make them appear sufficiently full.

Lighten up window treatment to a more contempory look.Paint walls white. Add orange or blue green accents to coordinate loveseat.. Let cherry wood tones be the only wood tones. or refinish to bold color or lighter wood tone. Art is easily available to pull the color scheme together.White bed with bright pillows ,throw.

I would go with a large blue & white patterned rug & stay away from tans. Good luck :)

How does this look
Yes- drapes will change to longer fuller and am thinking orange
Pillows will change too.

following

No orange drapery panels. Pick another color from the rug and what about putting the 3 seater sofa on the window wall?

They are both equal size large sofas with two big seats that can seat three
Other color for drapes- blue would be too much blue.
Don’t really see green or aqua in the rug.
Suggestions?
