Either porcelain or concrete is good. Finding a non slip product is the most important attribute. Take samples home, get them wet and slip your bare foot across the paver to test it before purchasing..........

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.

We went away from standard way. The patio builder had never built what we wanted before, but he did a fantastic job, and he thought it was great too and took photos to add to his portfolio. The roof of the patio is skillion style that is canter levered over the gutter and slopes away from the house. I don't have any photos and it is dark now. I will take some tomorrow if you are interested. I think it is very cool and a bit different. The gaps are in- filled with polycarbonate. We have just had a severe storm...patio clean and dry. It has actually given us an extra room for prob 9 months of the year.

My friend has an outdoor kitchen and in winter, it becomes useless. One kitchen is enough for me!
