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.

hi Mamta, you have done quite some work already. My suggestion would be that you add a few wall brackets to add more green the balcony. not the Vertical wall-features but the wrought iron brackets which can hold clay pots.

@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.
