Looks much neater now.

Looks like the drain that the down pipe goes into isn't working as it should, over flows before water enters the drain. Love the random pavers, these could certainly be reused adding a few more to replace the bricked area all on one level as this would enable a better space for outdoor table and chairs. The pergola is tired and would be great if as you mentioned could be raised up a bit, depends on what the Body Corporate will allow, a couple of see through panels inserted above next to the building would help with light. A BBQ kitchen on the back wall, plus I would try to re swing the door back to it, the door gets in the way as it is, can it open inwards opposite the sink. Certainly keep the garden beds it will help soften all the hard surfaces, taller planting along the boundary will also add privacy cheers

I would paint that wall a dark charcoal colour and arrange a beautiful garden, with an emphasis on drawing the eye down or towards the middle as opposed to leading your eye 'up' the wall - think some nice mid sized flowering plants or interesting trees, birdbath, garden lighting or water feature. With the wooden framework in the foreground of your image, is that for an outdoor entertaining space? If so, I'm just wondering if it's worth placing some horizontal timber slats evenly spaced apart from underneath that beam to help prevent a view of your neighbour's roof unless you're standing out in the yard? I hope that makes some sense :)

Face it - gravity sucks. Your house was designed to be supported by the "poles" or are they stumps? You will need to carefully assess the value in removing them all. First you will need to engage a structural engineer to advise you, and he may suggest long steel beams that run across from one side of the house to the opposite side allowing the supports to be removed. However the financial cost in installing these long beams (and additional structure to support the beam ends) will be significant - there is no cheap fix. Once you have paid tens of thousands of dollars (maybe more depending on the length of the spans and ease of access under your house for installing them) you will have a large, open, low-ceilinged space with the proportions and feel of a shopping centre carpark. The structural engineer will need deep steel beams depending on the span between the walls, and this will reduce the clearance under the beams to much less than your current 2.1 metres. Save your money and engage a clever designer to find a clever solution that works with keeping the supports, and you will get much better value for your spend.
