Florence Broadhurst patterns are available in both fabric and wallpapers. Florence Broadhurst Available in graphic and bold or eclectic patterns you could consider patterned fabric blinds on the 3 windows and use the same in the kitchen window. Another use could be behind a glass spashback above the kitchen bench. Her modern designs from the 1960's are vibrant and eclectic and are widely available. All of these could be used with the right injection of orange, turquoise and teal to accent the kitchen and tie the rooms together. There are also rugs available in Florence Broadhurst design if you wanted to keep the pattern on the floor and you could add some shutters on the 3 windows for a different look in either whte or charcoal/black.

Your design scheme has a very traditional European feel. I would continue with this and look at a couple of Louis chairs. The link I've attached shows one with a mix of rattan with an upholstered seat cushion. You can also get them with an upholstered back and arms. However I quite like the rattan for contrast so it's not too matchy matchy with your sofas. http://www.canalside.com.au/productimage.php?product_id=115&current_image=1 You could then add a scatter cushion to the chair. Have you thought about also adding a couple of scatters cushions to each sofa, in a silk or silk like fabric. Check out Kaz's Samara range. Not sure what colour to recommend as I can't see your wall colour clearly but black goes with most colours. Oskuee's rugs are lovely, just make sure the colour ties in with your colour scheme. As you have plenty of dark timber in the room already, consider a glass and metal coffee table and lamp tables in a gold finish. Gorgeous crystal or mirrored table lamps and an ornate gold framed mirror over either the chairs or the sofa to finish off the room.

I like the idea of a timber floating cabinet no wider than the TV, which could be purpose built and installed given the wall is brick. Unless you are handy and can do this yourself? I would match the timber to your floor, if possible. I say cabinet instead of shelves because you are wanting to hide the wiring, etc, and a cabinet will do that where a shelf will not. The raised platform you have for the fireplace is really attractive and a floating cabinet will not detract from it, I think.

I know it's going to be controversial, but hypothetically, if you did move the TV to the opposite wall, maybe you could swing that whole lounge suite around to face it, then set up a lovely round dining table (as suggested above) on the original TV wall. It looks like the TV is in a walkway area of the room - if it was on the other wall you could put a nice blockout roller blind on the window next to the fireplace and make the loungeroom feel more cosy and private. BUT... there's obviously good reasons to keep the TV where it is, just throwing it out there!
