Lose the mirror ball. I think the hanging chairs are even a bit too much... perhaps two would be enough. It would be lovely to get out of the pool and lounge around in one of those to dry off.

Our house is similar, but we are empty nesters and down sized about 4 years ago, our needs would be a bit different to a growing family, we are currently in the throes of having two smaller rooms made into one area to further open up a previous renovation to give us a bigger open space..we also have an ensuite and a combined laundry / second laundry space. The good thing is that being a brick veneer house the reconfiguring is relatively easy with modern technology and big beams. As above try and have a big open space, we have been out of our home for a month now and still a way to go, add living away from home to your budget or stay with family. I will try and post the plan but here are a couple of journey pics ..the last photo was before trying to show how the two rooms decided the space making the living room very small and a bit dark...the aim of this project is to have space for a bigger gathering than about 4 people before overcrowded. Light is really important, nice big windows essential, the darkness of the living I thought I could live with, but it did get me down, I a, looking forward to having a much lighter space

Not sure how it would go in Brisbane but what about trying a conifer? They grow fast and very tall. You can shape them or leave them natural. They are plain and certainly not tropical. Maybe speak to a local nursery and find out if they would grow in the sub-tropical climate of Brisbane first, as they are usually in colder climates (Sydney and south). Leightons Green Conifer – Leyland Cypress http://www.evergreengrowers.com.au/shop/hedging-screening/leightons-green-conifer-leyland-cypress/ Your quite limited if there's not enough sun and you dont use bamboo or tropical plants. Many other screening plants or hedges wont get tall enough for that space and climate. I hope you find something.
