thank you for the options people... i was trying to think a bit of a contrast flooring .... slightly more browner ... ?? What say all of you ? also need the floor to have some texturing dont like absolutely smooth wood will make it feel like paper...

A thick concrete wall can keep your house cool. Steel will make your house hot unless you insulated the walls well. Insulated walls don't work very well in a flood zone. When they get wet, you need to tear them apart. You will need concrete for the foundation most likely unless you are driving steel pylons. There is probably a combination of the two that will suit your needs best. It would be helpful to know what you want to achieve by using steel. There are advantages to both. Steel floors can be cantilevered further. It is easier to make bigger window openings. Floor and roof spans can be lighter and quicker to build with steel, but the roof will get hotter and therefore need good insulation and need to be well ventilated. These are just general assumptions of certain building practices so that you know what to ask people where you live. The practices and resources vary from place to place and building something for a specific purpose can change the benefits of one material or the other. My best guess is that you will probably want to use both.

I often look at my home and wonder what color to repaint...but I think we have selected the most complimentary color and don't want to change for change sake. Consider that as well - I love the starkness of the white for the style of your home and if you feel you need an update, maybe there are other things you could do, ie: landscape, stone, etc. Not much help in the color department - lol.

So I am planning to do something like that in the picture. I really liked the use of the emperador marble and the balancing of the colours. In the second picture, I have selected the emperador for Wall as shown in picture, the light ones will be for the next three walls and the third tile will be for the flooring. I hope it'll look good.
