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.

Hi Sophia, I think a dark grey with a hint of mauve would look spectacular and keep the whole home looking cool. What's more, when your garden and trees grow, the greens will complement the colour. Then a touch of red in plantings of kangaroo paw, bottle brush or hibiscus or even a flame tree would make the neighbours applaud your colour choices for sure.

Is the pic of the house attached to this discussion exterior rendered in Taubmans pebble bay?

I wouldn’t render. I don’t think you need to. The pillar colour is the odd colour but I’d leave it for the time being. I’d put the money and effort into the landscaping inc a mature tree or two. If you’re still unhappy after the garden is in then rethink painting the pillar and adding render.
