@ minebathroom and @ Luke Buckle, our electrician has informed us that we don't have to put solar panels on our house roof if we don't want to for aesthetics or if for example the roof was old as you mentioned Luke. Panels can be placed on a shed or garage roof anywhere on your property if you are rural like us for example, as the power can be directed into the grid from anywhere the solar panels live and that doesn't have to be on the house roof. We would love to go solar but agree with all your other points @minebathroom, too expensive and expected lifespan and feed in tarrifs are very ordinary but then there's also the back up service too, will the company still be around in one year let alone 10 years. When our electrician got his solar, he got such a fantastic tarrif rate which was offered at the very start of the solar revolution, he was recieving a cheque or refund of something like $500 a quarter but the rates are so low now, there is certainly no chance of recouping some of the instalation costs, although I wouldn't be so fused about that if I thought I would get say 20+ years out of the system before it begun to possibly fail in some way. Things do have to get allot more reliable if nothing else!!

Ok. I am a little confused where to head. I need a future vision for all components of house and fence to make the little decisions. The pool blue tiles I love but not sure how to tie in with all the fences internal and external and with house especially if this green goes anywhere else ? But I have bought a " green paint" dulux scott's pine very similar to what was there but it is quite wet here so I stumbled on a photo edit option and have done an unskilled mock up on a photo and taken a photo of it in the meantime (as I couldnt work out how to save it!!! ) But although the green is lighter than actual paint I have bought I can actually (ok it has taken me a while) see how the green would work. But if I do that what would I do will both my green fence and my maroon fence from the outside. I also tried to track down junior navy and couldnt find that colour anywhere? I have slate in need of a little tlc inside front door which I love. I know for some people they find it hard to clean or dated. Its individual and I am beginning to subscribe to conscious consumerism. Lets be clear my house has had renos from some different eras so was and is going to be earthy but eclectic and individual in decorating style.

If you look at these photos of your home and a comparison photo. Okay, the photos of your home may not be as neat a job, but the work completed is the same. Only difference with gutters, as mentioned by siriusky is the placement of the gutters on the boundary wall. But if a down pipe is required for this side of the home, then that ,is maybe why they have completed the job with the gutters along the wall not on top. An inspector will check everything and give you piece of mind. But the job may of been done correctly in the first place?
