For the fireplace inserts go ahead and do the green order a second set of panels that you store that are more neutral. In 10 years or five years you may not like the green anymore. It's possible you won't have access to different colored panels at that time. As for the color I like the ideas of going into those silvers it would coordinate very well with your blue couch and it will pull the blues out of the curtain panels. For the wall coloring use the warm golden color in the drape. There is one piece of the flower that has this color and it will balance the weight of a dark couch. If your room is small don't go too dark in this color. You could use it on the main wall and pick two shades lighter on the other three walls.

Blue gray window frames match the funky roof. The cedar is diametrically opposite on the color wheel as a orange tone. Usually the browner grays (sort of the light shade now on the stucco) do better with cedar to say modern, but since you have the blue gray, allow me to suggest that you just go as dark gray as you can - nearly charcoal on all the weatherboard. If you are in a high heat area (palms might or might not be - that might be the ocean on the horizon which might me an onshore breeze all the time) then you want a white. Not a blue-white but a warm white - bm maritime white is a good choice. With the cedar and the two blue-blue-gray elements, you need neutral without tone.

Thanks for all the great ideas everyone and sorry I didn't explain the polycarbonate a bit better :) This is along the lines of what we'll be using... http://www.psp.co.nz/building-brands/corrugated-sheeting/suntuf-polycarbonate The area is an absolute sun trap and we're hoping to use it as an extension to our living space, especially on rainy days! I've just sent my husband out to get a few pots of different stains for is to try - darkest brown (cedar) and a lighter brown (rustic oak) both by Cabots + the black we already have. Hopefully we can decide between one of those! I probably should have mentioned we will have black aluminium pool fencing running along the top of the second retaining wall - so the real question is do we keep everything black (pool fencing, horizontal fence, retaining walls and pergola) or do we go with a dark (or even light) brown for the pergola and retaining walls.... We just keep going around in circles at the moment. Decisions, decisions! Thanks again :)

It sounds like you've been through quite the rollercoaster with your building project! That's really frustrating to hear, especially when you had a vision that you were attached to. Construction dilemmas can be a lot to handle, and I can only imagine how the stress might have piled up over time. If you're feeling stressed (and who wouldn't be in a situation like this?), you might want to consider working off some of that tension. Since you're into home design and creating beautiful spaces, you might appreciate the aesthetic and functionality at Hitsona's fitness studio. Sometimes a little self-care and a change of scenery can inspire new ideas for other areas in life, including home design.
