You might try 4'x6', landscape format. We typically start by centering the object around 5' above the floor. Might work better a little higher but you can try it out with tape.

Thank-you both for your input! I think I'm tossing up between putting the chairs in the nook or against the long wall. If chairs go in the nook, it's cosy and there's more walkway space as you said, Luke, for beanbags etc. However, what would I do with the 2m wall near the entrance? Would seating there be a bit odd? However having the screen in the nook would allow for a longer row of seating I think? So potentially more people could fit in, although those sitting near the door may have an obscure view of the screen. It seems like both options have pros & cons! We don't have anything that needs to go in, so to speak, although plenty of seating options and tables for drinks etc would be really great!

So worth it and definitely an investment that will provide great return should you eventually sell! Love the rug as well :) temple and webster always has some great stuff.

HI Kath, Yes the larger lounge needs to be moved in front of the blind and .8M out from it. (you need .8-1.5 meters walkway space between any objects and any less looks cluttered) The 2 seater, needs to be moved 90 degrees to touch, almost, the 3 seater and facing the fireplace. Position or purchase a new square coffee table to fill the void this will create and a matching one in the large space facing the TV. Move the TV Cabinet, which absolutely is too large for the niche, to the large wall. Decorating is about matching shapes and proportions. Pop it all above a rug that sits under the entire lounge suite. You also need two artworks of the same size for either side of the fireplace. As a customised artwork specialist, I would suggest, contemporary styled collages in a your natural palette with accents of red and a green accent. Collages would add much needed texture to your space. Large frames are also required in a metal to match your fireplace. Keeping the colour palette simple, like I've done here, is the key.
