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.

@ Ba Beltramo, I think this dilemma might be better solved if we we had pictures, as suggested by rahnch but if that is too difficult to provide, it would help if you supplied more information about exactly where this pool sits as opposed to the home and what size and shape it is including the lay of the land, pool fencing etc... I'm a little concerned about some of the suggestions that even talk of possibly destroying the pool although I have nothing personally against the suggestion providing you are well informed and take into account what will best suit you personally. After reading you dilemma heading again, "Re-design the space AFTER pool" I'm now assuming that the pool may already be gone and you have a huge hole where it once sat?? If that's the case, then it could be as simple as filling the hole in as you suggested yourself. If the pool is still in place and you are considering filling it in, then I would be concerned about your thoughts to effectively destroy it when I personally know just how costly is it to have a pool in the first place with many people who could only dream of having one!! At the end of the day, your property must work for you but I would hope you give it allot of thought before you do anything.

I would definitely choose small backyard with the pool! Our backyard is rather small so when we moved in we decided to use the space as much as we could! We called the guys that install fiberglass pools, since we heard that these are great choice and more customizable than the others. We are enjoying in our backyard every day!

We have Paramount in floor pool cleaner with hedge/plants around pool. Infloor pool cleaner is awesome. I vacuum pool 2-3 times a year.
