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.

the pictures you see online of glass walls and roofs are those not from India. and the usually have a large property and the home itself is secluded enough to provide privacy. for heat, they have a centrally controlled HVAC system that is on 24x7 to regulate heat and cold, plus the glass is often reflective and double, to provide a modicum of insulation. since you're a resident of Hyderabad, it would be more advisable to have just a skylight or just large french doors and not got for the entire combination. hope this helps
