Privacy could be obtained with a screen, placement of potted plants, an open bookcase, but I like your idea for a curved track with a curtain as one option for visual privacy. I would rotate the dining table 90 degrees and move it towards the balcony. I would remove those two chairs/tables because the layout of a single chair that far apart from another chair does not work. You may need to move the seating away from the main entrance because it looks like you walk in and you're on top of a loveseat. In such a tight space with so many doors that open in to the main living/dining - my advice is to keep it simple. Scale the furniture properly and have pieces that are multi-functional. Example- an ottoman that can serve as seating. A bench at the dining table to seat 3 on each side. I would also place two smaller loveseats facing each other in front of the fireplace. This will give you an "entry area" (along the back side of the kitchen wall) and help to define the living from dining rooms. Even if you don't have a formal entry, try to create a bit of space to welcome people.

I'm not an architect, but perhaps that drawing room corner could be done as a diagonal wall with French doors.

You can go for normal marble finishing. and can go for installing a HD projector. You can visit ProjectReview. They have huge collection of projectors in different range. This will definitely give an elegant look to you drawing room.

Hi krithi It appears to be Balanced. Few options like sofa cover, wall clock, photo frames above and beyond chair, can be refreshed to New. Go for quality paintings and see if you can change wall color to white. Best regards Naveen
