I know of this veneer concrete flooring as an alternative to lished concrete, however as a veneer, it is a thin pour over a solid substrate. Unfortunately the very nature of a first floor is suspended, (although sufficiently supported) it will have flex and movement in it, which this opttion does not favor. The reason is due to cracking, and resurfacing the cracks are unsightly. As a designer, and working on my own renovation, I looked into this option and the technical implications for my build. It was not recommended although possible. I did however find one other alternative, called xlite, which are large scale tiles that replicate the look of stone, marble and concrete too. The tiles run in 3000 x 1500 sheets, so Grout lines are limited and hardly factors. In fact that the unique scale of tile, which is lightweight and has a fantastic thermal mass, great insulative quality is so different, makes this system a feature on it's own.

Hi there Nick, looking at your photos you look like a modern hamptons family which is lovely, do you live in a warm climate. I did like the photo you posted of the open plan living and think that you are on the right track with interior colours I have marked out how I would like the first floor, I have moved the kitchen to the end wall to line up with BBQ outdoor kitchen, plumbing for this would have easy access via the garage below. The white tiles look lovely and hard wearing for the entrance foyer and Rumpus room, the stairs in timber due to the amount of traffic even continuing in up stairs foyer kitchen dining living, Carpet in bedrooms and downstairs theater. Kitchen in white but possibly Shaker style white doors these are very popular. Using existing sliding exterior doors if possible from kitchen.Dining to verandah, I think this ceiling would be best kept white to help reflect light back indoors, the tiles appear to be in good order but you might consider changing these along with new upstairs flooring Some where for a laundry shute would be handy, actually a Dumb Waiter so you could move the laundry with ease both up and down! The roof painted a soft colour, grey/white or off white, the verandah railing could be the same colour or you could do glass. The builder had a very different style of house to what I think you are wanting. Your photo

love your Jarrah floors with grey..have you considered paving paint as the cheapest thin grey coloured flooring??

I will be the loan naysayer and go: Vinyl Plank timber pattern tiles. I did these in my kitchen and they helped make the room. Used Karndean, but any European brand should be fine (avoid American and assume they are using American or worse if they don't say the country of origin). http://www.karndean.com/en-au/floors/landing-pages/new-looselay-longboard?gclid=CjwKCAjwspHaBRBFEiwA0eM3kQ7eEFPH5FlK2IwV3o7ZsbbmJ19srG0OM_tWK5dhPMNyDdwxGPUr4BoCoYcQAvD_BwE Caveats: Ground must be FLAT. 100% flat, ruler FLAT. If not you will have to level. If flat, you can lay them yourself. Our floor had to be levelled and it was tough. still got a few high patches and gaps because of that. However I have done it on a concrete surface myself since and it's beautiful. Benefits: Nice and soft on the foot. (less ankle pain) single tile replacement. Looks fantastic. No PVC glue fume issues and fairly resilient. Do be wary though of metal chair legs scraping the floor. Waterproof! when installed right with no gaps! (why I would choose them in a kitchen over timber or Eeek carpet!.... Yes previous owner installed shagpile carpet in the kitchen).
