I can see a dresser area outside the bathroom in the floor plan and a separate wardrobe area as well. You can make an exclusive wardrobe and dresser area for your daughter just outside the bathroom. The wardrobe space can accomadate a long study table with wall mount bookshelf and a mix of open and closed storage. On the same wall you can make a sleek wardrobe for your son. Trundle beds are also quite in these days, you can place a trundle instead of a regular bed. Place the bed against the same wall as shown in the floor plan but tucked away in the corner. On the opposite wall you can get a nice kid friendly theme on the wall and create a small seating. Use all white furniture and add pops of colour through curtains and bedding

This is a fabulous room. It oozes a bygone charm that you would lose by adding false ceilings and tube lights. Please don't! Go all out to preserve this magnificent floor and the beautiful furniture. That mirror is superb, as is the old painting. Keep the wall colour as is and change the upholstery after polishing and keeping the beautiful wooden furniture. The upholstery is mismatchedat present. But the different styled armchairs look very comfortable. Keep them. No modern furniture will give you such comfort. When you re upholster, refrain from choosing firm foam and such nonsense. It is far better to have good quality down or cotton, which moulds to the body shape. Invest in a high quality traditional patterned Persian or Kashmiri carpet for a restrained stroke of colour. Your upholstery should pick up colours from this carpet. So should the curtains. Please never even consider vinyl blinds, horizontal and vertical. If you tamper with this room and remodel it to be 'modern'- you will lose a treasure.

Hi Farooq, you should go for wall paneling on that wall with a concealed door. The wardrobe can be a part of the unit in front.

I feel partitions are not needed. You already have too much for the space. Adding a partition will shrink the space further. The simplistic solution, you do not wish to discard any furniture would be to paint all the walls in lighter pastles. And use some wall painting frames to highlight certain walls.
