Hi,
I have design your multitasking room keeping in mind all the requirements for a living, dining,home office and a bedroom. I have added a sofa cum bed with side table and centre table and a rug. Wall which has custom bookshelf, tv unit, wardrobe and lots of storage. There is study corner with desk and storage shelf in niche. Have kept your existing furniture piece in shallow niche. There is also a folding dining table for 4 which converts to a painting when closed. Color scheme is neutral. Hope your daughter likes it and would love to stay in there.
