Hi there
I think you need to be prepared to shove sofas around in various layouts till you find the one that works for your. The first thing I notice is that you have all your furniture pushed back against walls - this actually makes a room feel cramped (ironically)
Can you try moving your large sofa to be perpendicular with the wall (in front of the two seater and forward from the french doors (someone sitting on them should be able to look outside)
Take your two seater and place it opposite but again inset from the window. You now have a cosier set up and more intimate when you have friends around. Do you need or have space for the armchair with this set up?

If you do, swap the three seater with the two seater position and place the armchair at 45 degree angle next to the two seater.
Once you are happy with a room layout that seems to use the space more, we can start on the next phase.
All the best!

I like the startup of the layout effort for now, but might help you with an entry defining screen panel, look at the crestviewdoors.com website for the midcentury modern screens - this could go perpendicular to the door at the edge of the tile. See the paint grade 4 x 8 screen panel in this profile http://www.crestviewdoors.com/order/redi-screens/redi-screens-oxford.html painted in the trim color - behind the navy chair. Try a sofa table or desk behind the settee to push it forward and try a pair of lamps, and perhaps a sculptural element between to visually make a lot of the opening through. Try ASV's layout too -once you really love that, we can layer some art and perhaps a rug. Maybe search the leading fabric website s- beautifulfabric.com is a fave, so is calicocorners.com - you are watching for a print with color s of what you have that speaks to you.

The couch and the settee are two completely different styles. The chair and sofa work together so I would get another chair and or coffee table and create a great conversation area. You could put a console table where the settee is also.

Thank you all so much! I will start playing around with the sofa layout.

Great! Keep us posted :)
