Just a thought - Have you tested the existing cladding for asbestos prior to removing? Some of my coastal clients also feel the need to 'fill' the corrugations at the ends prior to capping or butting up to end frames: to dissuade small creatures from also moving in to a nice new home. Colorbond Surfmist will look great and horizontal will help to balance your homes height, however, it also gives ridges where dust and dirt sits and so needs to be hosed down more often - probably a good idea as it removes some of the salt as well. Good luck with the reno, the Architects image looks great.

Your colours will look quite good. Don't forget landscaping will make a massive difference so have a look at that as well.

You are asking Houzzers to do too much research. Post images of the colours and bricks etc and you are sure to get comments.

Your brick is very dark, have you decided on your mortar colour? I would consider matching your cladding colour to your mortar colour if you are using a light coloured mortar. So much depends on the design and style of your home. I would probably avoid matching the brick colour as you will need a good contrast, so don't go with Monument or Domino! It is impossible to tell without knowing what your house looks like. Have you considered engaging a colour consultant as it is a big decision and there are over 4000 Dulux colours available.
