[houzz=] Here is another that uses the corner well. This also will help offset the lack of symmetry on the range wall as well. Your cabinet maker would need to work out all the measurements. The base drawers to the right of the range may need to be reduced in size to be the same as the ones on the left, which will also help balance the wall. This tall unit to the left of the range will help to balance the large pantry on the right. Where the below picture does not show it, you would have room to place a small matching wall cabinet to the left of the corner tower to balance and to balance out the space between the window. Then you can still have some type of unit to the left of the sink with the appliance garage, but it would not need to be quite as wide and would give some space next to the sink. Look at this more and see what you think. There are some very unique features to your plan. A very high level of customization and much thought has gone into it. It is going to be beautiful. Would love to see the final plan and pictures of the final product. Let me know if you want us to look further.

There was a similar discussion last week, maybe you can get some ideas from it: https://www.houzz.com/discussions/help-for-exterior-cedar-siding-trim-color-dsvw-vd~661559

Now for Mr 16 months... I really can't decide. His room is going to be on the cold side of the house, with not so much sun so I want it to get that cozy sort of feeling when you come into it. I was thinking yellow or orange curtains? But then I don't know what colour to do the walls. These are some fabrics I like:

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 :)
