Thanks everyone for your further comments. No problem about it being an old post, always nice to communicate with people about design solutions/problems. Jilly, I posted some photos on 1st January 2016, they appear further up in the post. Garden Beet Pty Ltd, and Morel Construction Ltd, both of your solutions look great, but our problem still remains the western Queensland sun which is pretty vicious on anything that will either wilt, fade or break down. It was quite a difficult challenge to come up with something that was affordable, workable and durable. I would love to have had plants because I believe they soften large "hard" exterior areas, but we have decided that we will do that with pots around the pool area. Still have that to do, even after all this time. :) Thanks everyone for re-igniting this chat. Jilly, hope you find something that works for you.

Wish i found this Q &A before. So many beautiful people advising and sharing here! I am Repainting Tropical Queenslander with dark red and orangy timber floors and this thread is so helpful. I painted Whisper white and it is throwing so much Green it makes me so sad I am going to repaint. I get loads of tropical sun in the north facing - with eastern morning sunlight. Was just about to go and buy Natural White just to cover it. Do you think it will be too dull/warm a colour. I do like a fresh feel and contrasting with vivid white decorative trims. The whisper white looks nice For a while in the morning while the morning sunlight throws read up onto it but then it returns to a green

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.

Hi Patricia, that sounds like one of those 'rules of thumb' that can't necessarily be relied upon. There are a lot of factors to consider when burying or partially burying a water tank including the hydrostatic pressure (if you have a high water table there is a change the tank could float right out of the hole when empty), soil pressure which could distort your tank etc. I guess the first question I would ask you is 'why a 30,000L tank?'. Are you diverting all of your downpipes? How much roof area to you have? There may be other space saving solutions that don't rely on you partially burying a tank. Happy to help if you want to send me an email or just reply here.
