Yes, it does come down to personal taste, but the overall look of your initial kitchen that has the concrete look tiles is beautiful. It would appeal to a wider audience too I think than the navy blue. If you concrete look tiles looked like those in the picture it would look great (as compared to a more matt look concrete tile which may not look as good). I say no to the herringbone look timber in your whole place downstairs. It will probably cost more to lay and I think it adds complexity that you don't need in a home as beautiful as an old queenslander. If you do decide on timber, I would stick with it being just straight planks. (Herringbone is flavour of the month now and I love it for tiles, but it makes a very big statement that not appeal to everyone if you are putting it in a much bigger area like kitchen etc). Good luck.

I have millboard, front verandah and back patio, it has been down going on three years, lust love it. Easy care good looking product.

Hopefully the rating, as explained below, should be on the code on each tile. Make sure they are vitrified as well so colour is all the way through. This way a scratch wjll not be white.

While I'm with Siriuskey regarding real timber, it would always be my choice, I recently saw a brand new house with very similar tiles down the long, wide hallway into and throughout the open plan kitchen and living area. It could be that it had a north facing, predominately glass wall allowing the sunshine to flood the room, but I was surprised just how good they looked. Perhaps you could check out the real estate websites to find an open house near you to check for yourself? I do think the quality, of both the tile and the expertise of the person laying the tiles, could make a huge difference also. In the meantime, perhaps your partner may see the light before the final decision is made ;)
