Start with super straight and flat wall studs and the $$ premium that that will require. Then the $$$ premium for the plasterer and the double layer of upgraded stock.

How about real water? http://houzz.com/photos/7604471 I also like the painting on the left.

You don't necessarily need only paintings as artwork. You can put some floating shelves near the dining space with some good crockery like plates or tea sets which can be used for occasions as well. On the wall in the living space you could keep either traditional or modern show pieces.

Thanks Nitin and Ideal Lifestyle. Sorry for the late reply, I don't know why my net is not working properly from the last few days. Ny way, I actually see the foating kitchen cabinet in google image. May be that it not good for our Indian kitchen. I love the drawyer system that offered in modular kitchen cabinet. But at the same time I have no patience to dry the the kitchenware (cookware/dish etc.) after washing. Now we put it on the steel dish rack (commonly visible in Indian kitchen) hanged in our wall after every wash, which no need to first dry and then store. But I want to conceal the dishes, pressure cookers, kadhais in drawyers. In my dream kitchen big kitchenware should be concealed, hanging cookware like saucepan, tawa, frying pan would hang on s hooks in railing and open shelve for the dry goods in glass/tin/ceramic jar.
