Ideally pooja should be next to kitchen which is also preferred by most in AP & Bangalore. As per Vasu it should be in East or NorthEast of the flat area & while you pray you should face towards East. occupying foyer area is good but need to divert the flow to avoid walking with footwear in front of pooja room, so need to change the entry which I think difficult from Prestige as they wouldn't accept that change The other option is at Wash Basin However you should hire a professional so that you get right & full guidance. If you've already hired then you can demand to fulfill this requirement as well.

You don't necessarily need only paintings as artwork. You can put some floating shelves near the dining space with some good crockery like plates or tea sets which can be used for occasions as well. On the wall in the living space you could keep either traditional or modern show pieces.

Hello Gopa, You can do a partition with plywood on wooden frame. Go for a door with hinges as there is no benefit of a sliding door in terms of light . What is your intent for having a openable vs sliding door. Please be aware that after making an additional room the living room will look dark and long/ narrow. You can have a transome on the door in case privacy is not much of an issue. You will however have to depend on artificial lighting in case a full partition is done.
