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.

Tough ask to get the no visible fixings. Magnesium oxide board (see the INEX brand) would give you the light coloured look, sheet or boarded look. The product can be painted but looks great raw too, has a shiny side and a striated side so you can have a variety of looks. Good luck

Yes, our harsh Australian environment does hammer our external finishes but if exposed timber is coated with a good quality finish initially ( i recommend 4 coats minimum ) then an ongoing maintenance coat every couple of years, your timber can still look great many years down the track. People just need to understand if you want that beautiful natural timber look you have to put time in to maintain it.

Just wondering if anybody has painted the exterior of their home using Haymes “resonate”??? Extra points for pictures! 😂
