This is not the main living. This is a second living at the basement.so will be used for tv viewing and casual family time .Only issue is we will loose 3 feet on the right side as a landing space before entering the bedroom and also around a feet for the steps.After loosing this the area will be around 14feet *9 feet .IS it still ok for a sunken area or will it get congested?

I agree with divadeva. More lights. If you can add pot lights do it. If they're already there add task lighting and up the wattage on the bulbs on the pot lights (replace with LED and you can make them brighter because the wattage on LED is lower for brighter light). If you have all of that add decorative lighting. If ventilation is an issue find a way to move the air around or add air filtration. Maybe the HVAC is deficient. Maybe you can add a HEPA filter instead of the standard one that comes with the unit. Call an HVAC specialist to see if there is a way to boost air flow in the room.

Hello Sagar, This space is sufficient for a bathtub in a bath. Thanks, Nitin CORNERSTONE DESIGNS, Bangalore

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
