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

Hi Katrine, The renovation went really well - thanks! It's been finished for more than a year now - hard to believe!! I could only find one pic of the cladding that was easy for me to upload - here it is. We've been really happy with the FC cladding and how it looks. We replaced all the existing exterior weatherboards (which ran on an angle parallel to the roof) with the same Duragroove FC cladding that we covered the new extension in. Our builders said it is very easy to work with and it certainly went up very quickly. Their only comment was that you can end up with a fair bit of wastage as it often gets damaged in transit. The supplier they used said this is pretty common, however, and so they actually allow for it and oversupply somewhat to allow a proportion of damaged sheets - sorry I can't quantify this aspect for you. The cladding was very easy and quick to paint and we're very happy with how it has come up. If you're interested in details, it's painted in a new Colourbond colour called Gully. The darker trim (fascias, gutters, downpipes etc) is Woodland Grey. Good luck with your decision making. If you'd like more photos, let me know and I'll try to take and upload a few more. Cheers, Kate

I second James Hardie Axon cladding as it has a vertical groove that echoes the original vertical weatherboard. Or you could get some weatherboard custom milled to match the existing and just patch the damage without doing the whole house. In the photo below I specified the Axon sheet which was then painted lime yellow. Also be aware that some builders will suggest materials that will make their lives easier rather than what actually looks good and will be durable and long-lasting.

The eave ones are fairly standard. The cladding joins are quite ordinary.
