Nice pool, but a shame that your neighbours can see you through the fence, and therefore, you get no privacy. If you were wanting privacy of some kind, bamboo, tikka plant or even lovely conifers will look quite nice, also as a backdrop to your pool area. I would also place a beautiful urn or two strategically near the pool, to add character and colour. I would finally add an order of large stones for good effect.

Although we have very deep eaves and lovely large decks, we don't actually have proper shade at our new house so that we can enjoy the outdoor living. Trying to resolve this. Thinking about a big shade sail further away from house where we have a big table and chairs, and perhaps decorative metal panels attached to either the roof or wall cladding on the west deck. The sun is harshest during afternoons to sunset and so far we cannot use this deck for '5 o'clock somewhere' drinks.

I would also suggest a deck at the same level as the house floor. Merbau decking boards are hard wearing and reasonably priced $. Also look at a new sliding doors with insect screen built into the door frame as a second door. This will introduce cross ventilation and keep the mozzies at bay in the night and make your internal floor space appear bigger. I would also build a veranda over the deck and mimic the existing gable end of the roof ( keep the rafters high ) and use all laserlight transparent roofing material to keep natural light flooding in. You could also look at introducing a natural gas point and some outdoor power points for gas BBQ and entertaining. The space will effectively become your new Outdoor room - enjoy :-)

Composite decking such as Modwood is much more practical! Timber is a lovely natural material, however you have to finish it and then worry about the maintenance down the track. If you want to avoid stains leaching everywhere than composite decking is definitely the answer. As an initial outlay, it is 2-3 times more expensive.... You will get this cost back down the track when you don't have to refinish it every 12 months!
