Snaps would help.

The advise that you get from houzz.com is from professionals like myself and also from people who aren't professional but who enjoy commenting. The site is not really set up for solving very complex designs such as a complete house. I enjoy taking a few moments out of my busy day helping out when I can, but there is no compensation involved and I can't spend much of my time here. Houzz can also be used to find a professional to hire in your part of the world. We have clients who have found us through houzz. I don't know if there is a pro near you, but hopefully you can find a local architect for you to help you design your house. Of course you can post any questions that you have and you never know what great answers you will get.

Hi, You need an architect to get a proper floor plan. You can get in touch with me on 07838154046 or write to me at pkassociates8@gmail.com. By the way, where is your site located?

your staircase block is nice. use natural store cladding, if cost permits, else some nice stone designed tiles should also do the trick. as per the tile/stone, you can either go with the similar family for the rest of the wall painting. ensure the moldings/projections are painted in lighter tone than the walls, so that they do subtly stand out.
