Your house is going to blend in very well with it's surrounds once the timber has silvered off, if you choose to use colours like Colorbond Woodland Grey, Dulux "Pavings Stone" (left hand side of colour swatch in the image far below) and/or Dulux "Grey Mountain". Other darker colours that will work well in this setting include Dulux "Cambridge Hall" and Dulux "Nomadji" (mentioned before). These greys don't necessarily blend in with the fresh timber but look fantastic as the timber ages and the building is seen as a whole (see image far below). "Paving Stone" is a versatile medium, warm grey that looks really good as a render. It also works well as a neutral internal wall colour in rooms with lots of natural light. In the following image, Dulux "Grey Mountain" was used near the timber work and "Woodland Grey" on the garage walls to help the garage door become less noticeable. Remember that colours generally appear lighter than the sample when applied to external walls and darker when applied to internal walls.

The Bricks are OK, if you like them, keep that round feature deck in the brick and render the rest, or stone clad the feature and render the rest, or cheapest of all just paint the rest in a dark warm neutral and render the round feature in a lighter but similar tone. You have the windows to consider. If you changed the colour of them you could also change the overall colour scheme from warm to cool. Although a black and white scheme is current, it looks better on timber houses and in suburban and inner city areas in my opinion. There are lots of different elements to your house which would look more integrated if you chose a warm colour scheme with a maximum of 3 colours. You can even make the bricks work if you paint upstairs a warmer colour to match them and changed the tiles and front steps to wood. Wood integrates everything in a warm colour scheme.

Thank you so much everyone for your great ideas, advice and uploads. I've decided on glass for pool fencing, Dune for render colour, but still undecided about front balustrade and handrails. While I love the idea of stainless steel, I'm still not confident that a modern look will suit the front facade. I keep coming back to the classic look in Lesley's pic but wonder whether white powder coating is the way to go or whether it would be too busy for my facade as I have stairs/handrails to consider. Still pondering over too many choices!

Go grey as advised above, don't paint window frames if they are metal but leave alone, plant sasanqua camelias along the side boundaries (they can be hedged) to screen out neighbours & add greenery plus colour, landscape the front. Don't do white stones as they look dirty after a while and are blinding in the sun. I'd get rid of the stones altogether. If you are a gardener, put in box hedging and some standard roses (yes, I know done to death but they are charming), or draw up something on paper first - play with shapes. A garden makes a house look good.
