I have had my kitchen area painted with Dulux Cowardly Custard half strength walls for years now and I love it and never tire of it. I love how cheerful and clean the rooms always look and the colour is not overpowering. Other areas in my home have walls in green and aqua blue and the three colours mix together well and stronger shades of yellow can be mixed with it also. I have just redone the kitchen cupboards and did them in Cowardly Custard too with white benchtop and white glass mosaic tiles and my small kitchen looks so much bigger now. A pale colour will not make a room look smaller.

Thanks everyone for your further comments. No problem about it being an old post, always nice to communicate with people about design solutions/problems. Jilly, I posted some photos on 1st January 2016, they appear further up in the post. Garden Beet Pty Ltd, and Morel Construction Ltd, both of your solutions look great, but our problem still remains the western Queensland sun which is pretty vicious on anything that will either wilt, fade or break down. It was quite a difficult challenge to come up with something that was affordable, workable and durable. I would love to have had plants because I believe they soften large "hard" exterior areas, but we have decided that we will do that with pots around the pool area. Still have that to do, even after all this time. :) Thanks everyone for re-igniting this chat. Jilly, hope you find something that works for you.

We went with Monument and I am delighted. I was worried about it making the house hotter, but not at all as we added some extra insulation while the roof was lifted. We look over our roof to Mt Dandenong and it really feels like we are floating above the rooftops now (previously had a lighter color). I have also noticed there is far less glare being darker. Pic below is not my best shots ... but you get the idea. Forgot to add we also have a flat cliplock roof and used a combination of Monument and Dune on the house.

siriuskey, Yes, the courtyard is open to the sky (no roof over it), I assume this is what you mean by double story. Ref. below photos, I would love to get this look, especially the first and last photo, where you can see family living space from the first floor. I can't achieve this in my plan as it eats a lot of floor space upstairs. The referred plan (photos) has a very big void combining staircase, hallway and dining area. I know it is not easy with cooling and heating when you have such a big void. So, I explored a few ideas (with my limited knowledge on this topic) before achieving the current floorplan. I have also thought about, in my current plan, extending the void on the staircase to the dining area (it is more like L shape) but i wasn't sure if that makes any difference. keen to hear your thoughts.
