Go the diagonal! There seems to be a lot of dead space in the middle. It seems like a desk/office area near the glass doors. I would move the TV there at a diagonal over the fixed part of the glass door and circle that with the couches/seating. Couches don't need to be up against walls as they are usually heavy enough to stand alone. The feet of the couches should be on the rug and only just enough room around the coffee table to get to a seat at the couches and get to the TV. I would tuck the office (if that is what that table is being used for) closer to the kitchen facing the glass doors. The path to the opening part of the doors will then be behind the couches. Since you will be able to see the back of the couches you can buy sarongs/material to drap over the back like a shawl. Pick some that match the rugs with a very simple pattern.

Thanks everyone for your kind contribution and feedback. Thanks especially to allanaspree for taking the time to photoshop your ideas into the photos - the centre table looks much better with your simple suggestions J (see post) I’m taking it all on board and will post the after photos.

Thanks Siriuskey I lean more towards the hamptons style in your photos.. Love the softness and the flowers...I worried that bringing metal framed tables into the room they would give more an industrial look? I think I need to find an app that I can place furniture around the room .

I know what you mean about the hearth. I have slate in a crazy broken pattern. I’ve never liked it but I keep changing my mind on the replacement. I’ve had moods of small marble herringbone, blue and grey encaustic tiles, sandstone coloured stone look plus more. I think in the end I’ll go for a dark bluestone coloured middle size stone tile that will be neutral and go with a lot of styles.
