I agree with Fiona about the Ficus - they have shocking root systems and should never be used near pools, houses etc. The width of your retaining wall from the photo looks really narrow, so you are going to have trouble growing most things in there; even the Pittosporums will eventually cause structural damage to the walls. The width of any garden bed should be ideally 1.5 metres at least for proper root establishment. This seems to be hard for most people to understand, but the bigger the plant, the wider the root system. So either widen the retaining wall or you will need to keep the plant lower. The pears mentioned also will never work. 5 years is the testing time of a good garden. When first planted they can look great, but they often break down as they grow. The Ficus and Pears' root systems will keep on expanding after the 5 year period with the Ficus having surface roots that cause massive damage to paving, concrete etc. Google it! And I have seen first hand the damage done by another Landscaper's work, based on inexperience. Get professional advice if in doubt - it is worth it if you get a good one. Alison

Breaking up the great solid block of colour a little bit helps to hide it. Next is the choice of what to plant. I'm leaning towards: ficus pumila, climbing fig, which can be pruned to hug the fence tightly, Himalyan blue bamboo, (but might sprout on other side of fence as well, so should have a 60cm deep root guard or be planted in pots) or waterhousia floribunda, weeping lilypilly, which can be pruned to a narrow, non-climbable hedge but 30cm might be about as narrow as possible. I'm just a bit scared the bamboo will move into the neighbours yard too...You also have to be careful to not plant anything with massive roots that could eventually crack your pool, and it has to be tough enough to cope with a bit of chlorine... Then, put in a dip line so you don't have to water such a narrow spot. Good luck, and let us know what you decide.

horizontal anything is a no, the gap would have to be so small it might as well be solid. yes the vertical cable might pass but you are not allowed to be able to squeeze them together as then the gap distance is non complying, The safest one is the solid section PCA pool fence, or glass, or solid, to 1200 mm in Queensland, no greater than 100 mm off ground, and gaps not able to be manipulated, and to stop that you have to have horizontal section in the cable type, which then do not comply, cut metal screens if complying is OK. I would question the void, and if you know the reason for the void, than solutions will be able to be worked out, now we are asking why? Pools in adjoining yards are acceptable with pool fencing complying on both sides, no void is required. so the void sound a bit iffy, unless it is something to do with storm water, or a building requirement, so ask the question why. Pool fencing can be awesome.

Definitely an attached garage is always a big plus, particularly in terms of value and resale "tick boxes".........which is one of the benefits of the concept I threw out there a few weeks back that involved developing the more logically oriented extension that connects the garage across where the pool is currently.............which obviously involves moving the pool or removing it for a period of time before it can then be potentially reinstated............ My professional opinion remains firm that for the long term investment that is the superior outcome, better spend and highest value-adding option for the property, even if it takes longer and costs more to achieve......budget limit is one thing, but equally you can spend a certain "budget" limit to simultaneously achieve a "more expensive" & lesser value adding result...........let's say you have a limit of $500K but budget aside the arguably best value concept is more like a $650K exercise. A compromised spend of $500K can be actually the "more expensive" option long term in comparison to a higher cost but higher value spend, that perhaps could be achieved in stages or over a longer period of time, say building first and then eventually finishing off landscaping. Rome wasn't built in a day and I've written before about the time/cost/quality relationship and how managing those one way or the other will influence the long term outcomes for a project, for better or worse....... We'll never tell people what they should or shouldn't want in their homes, but when it comes to resolving/identifying the most logical and profitable and balanced options/solutions for a certain outcome, well that's kind of the business that we're specialised in.............. I am also suspecting that there could be some misalignments/tension on the "client" camp/side (ie his wants vs her wants) of the process that is making it difficult to properly prioritise and robustly shuffle the various project variables........the "in limbo"/"going round in circles" is a classic symptom and ultimately requires resolution somehow.........
