Pictures of your dining room and kitchen would be helpful.

Excuse my duh-ness but i'm having difficulty trying to follow whats going on here. Are these two photos an exact replica of your house and pool ? If not a hasty sketch with dimensions could help a lot. By kitchen wall do you mean the wall behind the bar ? And where is the pool wall ? Are you considering the covered area as being "inside" ? Sorry for all those questions lol Sometimes when you have a design problem you need to turn it inside out or on it's head. If you can't beat it maybe embrace it by making a feature of it : i.e. contrast by having the lightest colored pool surround and a great blue or tile inside and under the overhang, something that will echo the water color ? If you have a great covered area as in photo you'll most likely be spending a lot of time there and it could be soothing to be able to sometimes retire into a darker inside. In my book, 10M isn't small and also contrasting two floor colors doesn't necessarily make a space seem smaller and confined and may in fact even open it up. Could it be that you've thought yourself into a box here ? Sometimes one needs to give it all a good shake up and see how it resettles.

Doesn't look worth it from that photo!

Sorry for the delay....well I still haven't quite got to the floor yet. I have friends and family advising that black would show up every bit of dust etc and one friend who had a shiny black floor and felt that she was forever mopping, and if the light shone on the floor on the wrong angle you could see where the mop had been. I think this would frustrate me too much especially with young children and a cat so I think a whitewash look could be a good option, or reclaimed battered timber perhaps.......see why I haven't chosen the floor yet. Lol. You could always go a black but a weathered matt reclaimed timber that could look good too. Good luck!
