If you like the view, you could orient the furniture to face that way. Otherwise I'd treat it like any other wall and do your furniture placement as if they weren't windows.

Wow, nice space. I can see why you want advice. Open spaces are difficult to envision. Is it open to dining and kitchen as well? Can you do pic from front door and to the left side of room. I can't tell where tv is going, please point it out.

Having said all of that, the view from windows looks great, so I would focus on that, minimizing window coverings. Looking forward to see what you do.

Post a sketch with wall dimensions, openings etc. Post specifications of your sectional all measurements. Then i can do a scale drawing with answers to your questions. Sectionals are room hogs so hoping you measured carefully before you bought? If not, put order on hold until you verify it will work in your room.

These are the views of the kitchen which is open to living room. The tv will go on the wall straight ahead ...I am also attaching the how the old owners decorated. As for the sectional ...the room has plenty more room!
