Is this wall above ground or in a basement? Water penetration isn't good so you need to find an inspector (home insp or mold insp) who can examine your roof, gutters, siding and who has an "thermal imaging camera". Lesley is on the mark about mold which needs moisture to grow. So, have a pro get up on your roof especially in the area near the water stains. Another tip, get it done before winter and bank on tearing out that wall to treat the wood studs with bleach to kill anything.

Your choices don't flow well to me. The flooring in your photo is pretty (very dark...are you okay with it showing every footprint, smudge, and dust bunny? If so, that's fine). From all of your options there I would do white cabinets with the Himalaya White granite. But you said ignore the granite. :) I would go for the gray cabinets with white quartz everywhere in that case, but personally I'd worry about gray cabinets being very dated in a few years. Is there another quartz option that you could pair with the white cabinets that is light in color and maybe has some movement, like LG Bianco Drift?

first of all, Thank you guys for those valuable inputs. yes, as far as cleaning goes, its just been finished installing and I have asked them to clean them up. And also, I observed that the frosting on the glass didn't look that good, so I am going for the filming on certain portions of the doors n windows. - Is there a particular quality of films that I may choose for this ? - Yes, lighting is definitely the criteria I had in mind which can bring up the finish to this. And i am worried about this , as I did not go for False Roofing, bcos the ceiling is already at a low height. I should really refine my ideas on the lighting part. - the stairs are floored with white Marble stone..My mom loves it and the matting on it might hinder its beauty, but yes I will surely consider that as well. Thank you again.

I would suggest you to go for either actual stone cladding or ceramic wall tiles. Natural stone cladding provides a rich look to your walls and last comparatively longer than wallpaper. Although initial cost might appear to high but in the long run, it is the cost-effective solution for your walls as it requires very low-maintenance. Going for wallpaper would not be a very nice option especially if you are looking for something long-lasting. They not only get damaged easily because of moisture or other factors but would also stain your wall when they come out. Ceramic tiles is also a nice option to go for. You can get a huge variety in terms of size, colour, pattern etc. If you are looking for not-so-expensive option then ceramic mosaic tiles is the viable option. However, you should know that ceramic tiles take quite a long time to warm up during winters and cool down during summers. Wooden Planks would make your interior look elegant but it is very susceptible to temperature change and can easily get damaged with water. Also it might not go too well with modern architecture. Hope this helps. Thanks & Regards Kapil Surana
