Hi Greer, I am liking the suggestions of plants and hanging photos / frames. If you wanted to get some matching furniture you can use our website to create custom matching tables including perhaps a coffee table with some matching end / lamp tables and a matching sideboard / console. This would really tie everything together with a big rug and you can get them to fit your proportions as you can select the exact size and 40 top colours. http://tableanddesk.com.au/End-Table

Hang it over on the wall where they have the blue hanging, you can wall mount it there or use a lowline. You can put the sofa opposite that, but pull it in from the sliding door iykwim, so you create this traffic flow pathway from the kitchen to the 2 sliding doors that goes behind the back of the sofa. It creates a zone or nook effect for your lounge area and it will stop people walking in front of others when they are watching the telly. It will be a slightly more intimate seating arrangement but I think it would work better for talking to each other and watching tv. Seriously, its like they design these houses with no thought as to how someone is supposed to live in them.

I must be the OCD one -- Oak sounds nice , and looks nice , BUT the armchair is darker toned and a different style to the rest ; the coffee tables are the lightest ; the floating unit is in-between colour wise , the chevrons are nice but they don't relate to anything else in the room . By comparison , the couches , the sideboard ( that can't be seen in the latest pic ) and any 1 of the lighter toned items would work , or all three IF they were the same tone and style , would work as they are similar styles , and work together IMO . And a curve-ball -- the shutters in the same white as the walls means the shutters lose 90% of their effect . IF you had done the shutters in oak , and ALL the oak matched ( even if it was all stained darker it would be better , but similar styles / eras would be even better ) iot would look a lot better IMO . But I am weird , and I am OCD haha .

I would move your couch into the middle of the room and have it square onto the television. Have a walking space around the couch not between tv and couch. Add shelves on walls for games, books etc.
