That looks like natural wood so i wouldn't ever paint it, I would try to match the wood color and use a more substantial wood drapery rod next to it and remove the clock above it. Light jade pieces would be good and shiny too. Something inexpensive would be all green or white/cream Haeger (maybe spelled wrong) ceramic rectangular "planters" usually about 3 inches tall, 2 or three inches deep and 6 or so wide and other shapes also like small vases are easy to find. I think they are from the 40's or 50's so they would match the built-in style. You can pick them up at thrift stores for about five dollars and they have nice shapes. I agree with the other comments that a strong theme rather than random objects are key.

The butterfly drawers would be sturdy enough for grains and cans. I would just make sure the drawer glides are able to hold the weight. I usually look for Blum hinges and glides, they've usually held the best for prior projects. Lazy susans are usually what I love to use for corner storage. However Lazy Susans with a center pole usually cut down on storage space and can be cumbersome when trying to get items in and out. I love the ones that are mounted to a fixed shelf with no center pole. If something falls off it's just like reaching in the back of the cabinet shelf. Plus with the fixed shelf your able to store heavier items like mixers, pots and pan. Magic Corners I find to be awkward when trying to store items, and most you can usually just fit smaller items in the compartments. And the one complaint I get from them is that the glides get sticky over time. If your still wondering what options to go with, find a local kitchen showroom and try them out. Open all the options your looking at and see what fits your lifestyle and habits.

@Cornerstone design studio: Apologies for making big post; thought that more info will help. @Rupal ji, If it sounds like I dont need any changes; my apologies for that. Let me put it in short,"I am looking for options that give modern facilities without leaving good things from old charm/ comforts. " Thanks for the straight forward comments. I shall try to edit my original post to make it simpler and that looks open to new ideas.

@Rock Doc: Are you addressing this to me? I haven't actually bought these tiles yet - when I do, I will definitely be going for the handmade ones. They're a work of art and irreplaceable in my opinion. However, there are also screen-printed tiles available in the market in more or less the same patterns; the workmanship is of course different, but you get them cheaper, and they're also more easily available. You could give that a shot. I'd recommend Aakaar Flooring Solutions - they're here on Houzz and are able to provide both the above-mentioned types.
