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.

I'm personally not a fan of tile - very hard on the feet, I find - so I'd probably restrict tile to the wet areas and go for hardwood everywhere else. Our last home had wood in every room except the bathroom, and after 10 years it still looked fine. Even the kitchen looked good. That said, we didn't have kids running around in the house. Did (and still do) have a dog, though. Our current house has carpeting in the bedrooms, engineered wood in the living areas, and tile in the bathrooms and laundry. All three floor coverings have a similar greigish tone, so to my mind they look fine together, and meet the practicality and comfort criteria as well.

Maybe a cream or stone based white colour if the awnings are going to stay? This would also match the roof and could be ok with the gutters if you don’t want to change them.

Hi, just from trialing paint inside and being sensitive to undertones. It was a few years ago though but I remember Diesku looked very mauve. I recently painted a few rooms in my grandpas house Hogs bristle and it definitely has a slight pink under tone, similar to Antique White. I would suggest getting a Dulux colour expert out to make a suggestion. We have done it & it's worth the money. They will be able to make colour suggestions where the undertone will compliment the woodland grey not clash.
