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.

If you seek a modern look for your house, then I can recommend our Ebony range. These bricks are very smooth and have unique dimensions. Alternatively, if you want to mix things up and put some really stone like looking bricks in as features, then our Tierra range will work for you - thinking the Toledo or the Bilbao. They will be the colours that suit. These bricks are really unique. Handmade, incredibly textured and varied. Have a look at these options and see if it helps.

Looks like colorbond or scyon wall cladding, concrete render painted white/off white and 'apollo' bricks by boral.

The silver will look quite good with your colour scheme. I would probably change some weatherboard for Scyon Axon just to change it up a bit. Also use Scyon Axent for architraves and wall corners. Don't forget eaves and veranda ceilings, etc. as a really nice looking feature use HardieGroove or maybe even some timber to break up the acres of painted surfaces.
