I'm not against colorful homes. There's bright, and then there's too bright. I wouldn't go with persimmon for the whole house. The photo you provided has lots of white trim which offsets the orange, but your house doesn't have that much trim (unless you were planning on adding some, which I think would look good no matter what color you ultimately choose, but even so, I wouldn't go with persimmon for the whole house, as it's still too bright). To repeat what @nwduck said, the other homes in the neighborhood don't appear to all be done in the bright colors, and so yours would stand out too too much. I like @deco's idea of the bright door, if you really love a bright color. For the rest of the house, any more subdued color would be fine, along with additional trim around the windows, and assuming that your siding color coordinates with your roofing color.

I think this piece is quite lovely. It appears that your couch and chairs have dark wood so I would be tempted to stain or paint the buffet to match these items. Changing the large modern handles to smaller antique ones might help to make it less bulky looking and tie in with the other items in your room.. I like the idea of putting a mirror in the upper door, however much as I like the criss cross effect in the sample pictures, adding more detail may conflict with the curves in your sofa and chairs. You could look for a decorative detail that has more subtle style. As for placement, it might go on the short wall where you have a bench or even on the wall where you have your table with two chairs, one on each side to balance the look.

You're Welcome Mr. Patel :) Yes there are some plants that are better suited to indoor environment here's a guide for the same: but no plant can survive indoors indefinitely. you will need to to keep rotating them weekly or every 2 weeks. are you partial towards glass then sure it can be used. maybe paneled glass partition or a stained one like you mentioned earlier like these: The room does seem a little cluttered, which maybe because of the many different styles and no of things too. I think that can be helped by lightening the space a little and maybe bringing in a bit similarity specially the side tables and coffee tables . i have suggested the sofa upholstery color in the previous comment. shades of sage in velvet. if not then light beige in linen is also a good option. Something like in this picture https://www.houzz.in/photos/architectural-digest-india-march-april-2016-farm-house-in-delhi-phvw-vp~70030021 https://www.houzz.in/photos/vila-by-the-sea-phvw-vp~55949655 https://www.houzz.in/photos/aptes-bona-fide-expressions-phvw-vp~112062304 https://www.houzz.in/photos/sex-and-the-city-phvw-vp~94528292 https://www.houzz.in/photos/brentwood-transitional-home-phvw-vp~99412992 some bright colored cushions and an accent piece of sofa or some bright table cloth might also be good. as for curtains that will depend on the sofa upholstery you use. If you keep the same upholstery i think a nice pastel color would look better. something light. you should also choose light cushions and carpet for these sofas. and if you keep the same sofas i think you should atleast change some of the tables. I would also suggest bringing in a little more light to the room if possible. I hope this helped you. :) Best of Luck, Purva Saksena

@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.
