It IS worth every penny... but floors?? Its luxurious yes but vertical applications ( backsplash/ wall in the kitchen and bath) have less maintenance. Ialso would prefer to see it on a large island. Atleast upkeep is limited to a small area. Marble floors ARE gorgeous but they can scratch and be slippery when wet.

thanks Georgi02 I thought of the laundry incorporated in the bathroom or kitchen as you suggest but I want study nook and thought the two could go together hence the study/laundry space. I suppose it could go next to the fridge? But then I don't get a broom cupboard and study. After the comments here, I'm thinking maybe a U shape will be better because I can shrink the length of it I think from 3000 to 2600 which will give me more room in the dining and maybe it won't look as pokey as with the island. A question about the bathroom, would you put a vanity across the whole width and a narrow window above the mirror or have as shown , a large window to one side and therefore a smaller mirror above the vanity?

Depends on the installer and what bamboo they're using.

I’d go with timber or cork. Cork is great in a kitchen. Easy on your feet and joints and things are much less likely to break if you drop them. Especially as you age, tiles cause fatigue if you are standing in the kitchen for too long. Cork is now available in lots of different colours and styles including charcoals and greys that might compliment your slate. It’s not all 80s orange. Of course timber can look great too. Just make sure it’s ok for kitchen use.
