For a cheaper, faster and possibly easier option, take a look at this for some inspiration. The lighter colour of the walls may reflect more light and be a stand out feature of your home.

You could mount a TV which can swing out from the entry wall from the main house, or on the one opposite one near the back sliding doors, or on the floor, in the corner. Depending if you need storage on the back wall, you could have your lounge at the back of the room, or have a walkway between the back wall and the lounge. An easy moving lounge is great for moving into different positions around the room. I like the idea of the bar as a drinks trolley. Actually furniture on wheels is great for rearranging whenever you like. I usually have wheels mounted to furniture as I live on my own and it just makes it so much easier. Another idea, is a buffet across the wall of the three windows and a tele positioned placed above or on where the brick wall is in the middle of the three windows, and the buffet can act as a bar and whatever else.

A lot of the time they build a core filled concrete block wall then construct another stone wall against it. The concrete block wall takes the job of retaining while the stone is for looks only. It does depend on what purpose the wall is performing. For example a retaining wall higher than 600mm (usually) needs engineering by a structural engineer which is easier to achieve with core filled concrete block on footings rather than just solid stone. You never mentioned the purpose of the wall which is a vital detail as there can be numerous ways to achieve similar outcomes.

Hi all, Sorry for the slow replies and thanks for the input so far. From what I've read online a re-inforced besser block wall should be about $600 p/sqm including footings in Sydney (Hornsby shire council area). Given the wall is 1m x 10m it should be let's say $7k including design and DA or am I way off? I'd also need to dispose of the current wall + footings but I could probably give the blocks away. The paved area is about 40sqm. Would it be safe to assume $200 p/sqm for concrete base, paver supply (travertine) and install (coping and surrounds)? So the wall and and paving would cost let's say $16k + fencing + cladding. This isn't too bad considering how much better it would look and the value it would add to the house. I like the flexibility the besser would give - render, cladding etc are all options. I'm not sure how bad it is structurally it just has a couple of spots where I can see the blocks have pulled apart over time. Below are some pictures of the bad spots. Also looking at the Amber website it says the maximum courses is maximum non reinforced wall height of 972mm (6 courses). It looks like my wall is actually 7 courses un-reinforced. The wall and pool was built back in 2003. I definitely think planting in front of the wall would help, as would removing the lights but I'm in two minds about whether to bite the bullet and do it properly or just hide it.
