You have very high walls so I would do a tall wainscot on the walls to create some warmth and decoration at the same time. Take everything off the walls and remove all the small little shelfs and decorations, leave only the big furniture. Then start over with the wall decor. Need some bold statements to create some balance and interest but not clutter. Add some larger shelves if you need shelves, something hefty and interesting. It's hard to see wall color and how it works with the upholstery. Do you need all that furniture in the space? I would thin it out. Remove one of the sofas and place the chairs across from the other one. Open up the space in front of the window. Add a sofa table behind a sofa along the wall and decorate it with a couple large vintage style lamps with some accent color (pull a color from the rug that you like) on each end and tablescape the middle of the table. Add a huge mirror above Bring that same accent color into the space with some bookshelf decor but not cluttery. I am not a fan of the drapes; something more neutral in a grommet panel style that can easily be opened. Hang them at the ceiling. They will look really nice because they create nice gentle folds if the fabric is a bit heavy for weight. Good luck [houzz=] [houzz=] [houzz=] [houzz=] [houzz=] [houzz=] [houzz=] [houzz=] [houzz=] [houzz=] [houzz=] [houzz=]

Your best bet is to have a residential structural engineer do a site visit and a soil test. As the home is only 10 years old, it is normal to have some settlement and additional settlement after 10 years should be minor. The fact you are concerned of future settlement should be a red flag. Additionally, you are concerned about moisture. Two red flags. It is your choice, but buyer beware. Best of luck.

Hello - do you mean paint for the walls? I have seen many bathrooms in other countries, not just India, that have a combination of paint/tiles so don't understand why this would be an exception

What's the height of your bathroom and which geyser type ( horizontal or vertical ) you are using at present, all depends on these two things. If you've not bought the geyser then you can opt for horizontal one for the convenience of installing a false ceiling and then on one wall install the geyser. OR You can have a FLAP customize beneath the geyser for the maintenance and have the false ceiling too. For any query, you can revert back.
