there is no perfect dimensions for an island. Try to organce space subdividing into smaller cabinets of 60x60 cms which is the max space for a structural division and works for seating area as well

Installing curtain rods at the ceiling is a great way to add height to a space, but the drapes will cost a bit more because they will have to be longer. You might get a better picture quality if you installed a projection screen over one of the windows which could be raised out of the way when not in use.

the design looks great . According to me one side of windows can be used as bed wall . we can have blackout curtains or blackout window blinds . You can even play with drapery to define the area behind bed. We already have seating in the room so next we can do is give a console/ study table with an puffe / chair to it. also one can add a bench at the end of bed. Size you can check on your Autocad . Bed wall should be the focus when one enters the room, so I feel the bed should be placed like this . Dimensions of furniture and circulation space you can work on. Also WC should be on the washbasin side to avoid Future leakages and dampness in bedroom wall. all the best

Hi Nikita, First and farmost, you have very beautifull coushion on sofa, from where you buy it? You can check the videos of Small budget Big makover first session series in youtube. In One such house in Gujarat, Muninder and Bishakha coloured the old sofa set with whtie (The sofa is like yours) and changed the centre table. Interestingly, the family also had your kind of sofa set and they also want some modern style. The architect duo did not changed the sofa, just changed the colour. Yes I found it in youtube. it is the house of Setu Upadhyay. the link is https://www.youtube.com/watch?v=85GNhyLeVnM Another suggestion is that you have many tables on the room. You can drop few chairs and opt for a single centre table
