I like the wardrobe/divan idea.Put it flat on its back with open shelves facing up .And put wooden covers with handles,so that it becomes a makeshift bed/divan with storage.It could be a cupboard with long divisions.You could put shelves there.Flat on its back(divan), standing the way it is(dresser) or standing up on its height by width side(wardrobe),any which way it is eminently usable.I do not go by the name"interior designer/architect"

Give search for home theatre door in houzz and it will give you a few ideas. But finally what you have to think or take help from interior designer is about the theme of your home as this door should also get aligned with your house theme. In general having hallway as part of home theatre is not advised so if you can change it, it would be better. But if you can't then at least install auto closure.

If you are a vastu believer, don't make the pooja on the west wall. Pooja should be on east or north wall of the house. Don't cut your store room as you definitely need one , rather shift it on the extreme upper side of the master bedroom. Don't provide an extra door in the bedroom for the safety point of view. As I said, by giving store room space on the upper side you get the symmetry instead of the protruded wall at the entrance of the master bedroom. Bed heard board is the best in South, then East, then West. So go for first two if possible. For further queries, you,re most welcome.

Hey! Normally the door and the trim can differ in colour if there is another element pulling the trim colour on it. for instance if you have baseboards (which India doesn't) or wainscoting. Then you can use the colour of the trim on those elements. Since yours is a single unit, go for a cohesive whole with the trim and the door. In case you like paint, go for PU, it'll give you an excellent finish and will last long. I personally love the while on your doors. so maybe go with a warm white core laminate? alternatively you could also select a colour from something in your living cum dining space! I hope this helps! all the best Miloni
