I really like the suggestion Modern feature walls. Combined with some greenery inside and out as suggested by chookchook2 , you can start to soften the 'boxy' look of the space which is now reinforced by the line shape and form of the couch you introduced in the updated image. If it is a breakout or meeting room could I suggest, budget permitting, some form of window treatment. Some simple and relatively cheap e-screens would add a degree of privacy, but more importantly remove potentially annoying distractions from outside; important if you are using the room both for work that requires concentration' .. or alternatively, impromptu meetings with others that may be held in the room. I do like the green, but the photo projects a rather drab uninteresting interior despite your efforts thus far.(imho). I think making a call to Modern feature walls should be on your call list. Something has to be done with that ceiling which I find not only distracting but is actively working against your attempts at creating a really inviting space that people will want to break into. I can a hint of a table off to the right in front of the window. The best breakout spaces I've used have the facility to informally and casually sit across a table with sufficient desk or table space to spread drawings, images and presentation ideas. .. It just doesn't work as well if you and a colleague(s) are forced to sit or stand along one side of a table with the yard providing tempting distractions when the focus should be on communication and collaboration. Mounting the TV and raising it would open the room up further and likely break up the 'box-iness' further. .. A bit beyond my field (Window Treatments) ... but you did ask. lol.

It would be great to see some of these images on your profile.

Fiona (from Gold Coast), I read my iPad in bed before sleeping,too. I know it's time to put it down and sleep when it falls forward and whacks me on the nose! Fiona_ab, I wish you could convince my daughter to wear hers! She used them initially, now complains it's too much bother when she's tired and just wants to go to sleep! Aaarrggh!

Be a bit careful before replacing the outdoor furniture with expensive items - thieves often have a first go, then come back a few weeks later knowing that they'll get another haul with this second haul being new! (low lives!). Think about putting up security signage as a deterrent- unfortunately house showings are prime time for thieves to scope out a home. If potential buyers ask about security your agents says "I'm not sure, there's signage...". I'd go shopping for second hand table and chairs that you can fix up cheaply (a coat of paint/stain is easy) or even some el cheapo trestles from the local hardware store and then jazz it up with coloured runners/placemats and outdoor plates/glasses when you're doing your open house - the buyers need a narration that they can insert themselves into easily - remembering that a lot of home buys have 30 minutes allocated to see your property and that's not enough time for them to be "creatively visioning their life in your home". I'd also put some large pots with seasonal colour and invest in some LED curtain lighting on hooks that they see can be put up/pulled down (for Christmas/parties) - it'll give buyers a lifestyle image in which they can see themselves entertaining family and friends. If you can borrow an outdoor umbrella for the seating area and some outdoor beanbags for by the pool you'll be on a winner that you can easily pack up and not have spent a fortune on.
