Here is a pic of our front facade and the right hand side facing south. Also open to other options not just render and colorbond. Would love some feedback! Thanks

apennameandthata i don't know... vertical is more shed like style, while we still have a colonial style base and veranda. Dust will be an issue here (although its not so bad in that particular spot on a river, good protection from trees) but pressure wash will be regular practice anyway. Thanks for all your suggestions and I will take all on board, especially sandstone ideas. I don't this I want this house to look pretentious, but how can I describe that, I am after some subtle "wow" factor or something a bit different, but it must look like we knew what we are doing and YES, I want it to look like high quality build and not a transportable house or kit home. The house rectangle is so simple that I worry it may have that boring factor in its looks and that is why I am looking for some ideas. My problem is a tendency to overthink but I hope I will find a balance at some point :) At this stage I think: galvanised tin everywhere (or that zincalum), rusty steel posts, aluminum windows with timber look, sandstone features around main door and sandstone chimney. We had a big flood last year and the spot never goes under water, its on high grounds even though it is only meters from the river.

Do you have a photo of the roof? I'm thinking of going with Dune as our roof colour

with surrounding bush the light grey green colour like Colorbond Evening Haze or Cove with some timber highlights for doors and verandah posts etc would be my choice
