Is there part of the house we can't see? Where is your front door? Just the double frontage like that is plain, but that was the style and not much you can do about it. The homes you are looking at do have a lot of features with opportunities to bring in other colours but there is nowhere with yours to do that and if you try it usually cheapens it. If you take the triple fronted house you posted, I would do the lighter green on the weatherboard and the deeper green like they have used on the window frames, I would do for the baseboards and the front door. I would keep the window frames and eaves white and paint the guttering to match the roof. Are you country? Are here any water issues for the garden? Instead of trying to do something with the house, I think I would be inclined to give it all a cottagy look with a picket front fence, nice entrance, a lush lawn and lots of plants for colour and lushness. The dark green baseboard will be a nice background for some small shrubs in front of the house. Weatherboards really lend themselves to that look. Don't forget the addition of old tyre swans - lol I notice you have small awnings over the windows - maybe replace them with some striped canvas ones in greens and terracotta - if you can get the combination.

If you want the standing seam look in the fielders range it is nailstrip in 265 or 465mm wide profile but you will need ply behind the sheeting. If you want a wide profile with no ply use revolution roofing maxline 340

Thanks for your thoughts, they have helped us with our decision. We're now planning on using the barramundi roof tile (it's a grey, a bit softer than the soho nights black. And not so shiny) with matching gutter and fascia. And the cladding in paperbark. I was thinking cream windows instead of the timber, so there's some lighter colours on the brick downstairs to tie it to the top. We can't match it exactly to the paperbark cladding because we aren't using aluminium windows, but I'm hoping the cream (which is supposed to be more of an off-white with this manufacturer) will look okay in the clad dormers upstairs. Fingers crossed!

Don't cover the bricks with bagging, if there is no need. Once the brick has been covered there is no turning back. As Kate has suggested, square up the verandah supports, with timber. Then landscape, landscape, and landscape.
