Photos would help us a lot but mint and grey usually goes well with charred oak.

If you are seeking a truly open feel to the floor plan you have shared, then using one material in the mail living area is the best approach to making this space feel truly open. Using a variety of materials on flooring chops up the space and decreases the visual footprint. I would suggest using wood, tile, or if you are on a tight budget laminated flooring for the living/dining/kitchen. Then use carpet in the more intimate spaces; bedrooms and possibly hallway. Save the tile for the bathrooms.

House in process of build. Dilemma about what to use instead of tiling walls. Came across a thread which suggested running the floor tiles up the vanity wall to create a feature. However I am not having a tiled floor but laminate planks with the label claiming100% waterproof flooring. Has anyone done this with flooring? I definitely do not want tiled walls. A number of queries..... 1. would the flooring still be affixed on the wall as the floor? 2. Would I take it to the ceiling...... so below and above wall hung vanity and above mirror? 3. Since I would not use this to feature the bath in the same room. What do you suggest I put here? The bath is a 1700 long btw/corner. I have never seen baths without some form of splash back? But I don’t want tiles.

I'd take a totally different route . It looks like there is that narrowish window in the lounge or dining area -- I'd look at whether you could make that into a ranch-slider ( yes , I am in NZ too -- if you say ranch-slider it confuses the Aussies haha ) . You'd need a structural engineer to make sure that wall isn't load bearing , and also electrical cables are able to be moved , but I'd suspect the load bearing bits would be the corners , and you'd be able to 'open up' that wall onto the deck . While it initially may seem counter-intuitive , you could then take out the door and that other taller window -- close it in and add a couple of small windows , or how about doubling down , and seeing if you can 'open up' between what you call the 2 windows above the stove -- have 1 long flat window along there , OR even do another bay window -- that will add more light , but also by taking out the opening door , you will get an extra metre of space , That way , you can do a different kitchen design -- maybe a wall mount oven , or a pantry , a breakfast bar in a different spot -- basically , plan the kitchen and the window placement at the same time . The advantages would be more usable space , more light , an indoor/outdoor flow but through the other room , not the kitchen . But with more glass actually in the kitchen , it will feel lighter and airier , plumbing won't be as much of a hassle , it will look better . The only possible downside would be the wall you put the ranchslider in will need to be kept clear , as you may lose a bit of space there , but the breeze and openness will make up for that IMO .
