Thanks for your comments, for this project at Roseville, the frame for the decking was treated pine, and the top decking and the side screen was treated pine size 90mm x 22mm, we used decking oil (intergrain) Ultra Deck marine grade,( you can find it at Bunnings) with a (Merbau) Tint, this gives the timber a hardwood look. if you want to use a hardwood timber, I recommend using (Merbau) it comes in 90mm x 19mm and 135mm x 19mm. The decking is looking to the backyard Garden, nice view,

I too own a Qlder and found it difficult to choose exterior colours. But I do think you need to keep the handrails the same as the other handrails - blue. The balustrading needs to be the same as the other - beige. I think if you want to put the red somewhere, put that on the actual steps and decking on the door level.

I like both ideas, however think it's good to consider the practical as well as the aesthetic you are wanting. Consider your space and picture how each would look in the space you have. To throw a few more ideas at you, here are a few pics I just found on Houzz. There are certainly some very cool designs happening in the architectural world. Just decide what moves YOU and to heck with what a builder thinks-it's not his house (even if he is a relative). :)

I really like the pic that LesleyH posted. The wooden rail will be 'warmer' to the touch too, show less dirt and tie is with the stairs beautifully.....I thin it will 'ground' the whole look because, if I remember rightly, the stairs and front door are the only wooden features and the rest is a lot of very modern light grey/white/shiny features. I think another touch of warmth in the wood will be beautiful.
