will you have more cabinets instead of the puja? if the view from the windows is nice, i'd put the sink under a window, so you have something to look at when washing dishes/cleaning foodstuffs. as for arranging furniture, the way they have it, they must think you have a huge tv, to need to be so far back from it. my goodness. besides, the couch blocks the balcony! i'd turn that arrangement so that the tv is on the wall with the loveseat, but scooted away from the balcony door, and then arrange the furniture accordingly, making sure there's room to get to the balcony. turning the dining table 90° will give more chair room.

How do you decorate your place, what kind of style, colors, and feelings? That will greatly influence the type of door you might want. Also, think of your budget, and whether you want to install it yourself or hire a professional (you don't need to tell us, just keep that in mind). Then look around Houzz, in the products page, they have lots of interior sliding doors and hinged ones, from elegant frosted glass in a dark wood frame, to rustic reclaimed wood planks. You may not want to purchase that exact model, but it might give you a better idea of what would fulfill your airflow needs without sacrificing style.

#1 is the only one that works with your doorways. But I would rethink the sectional pieces which look too large. You will need at least a floor lamp. Your table/chairs looks narrow in relation to your sectional - is it to scale in the drawing? You may not have enough room. I would use a sofa against the wall and two chairs on either end facing toward each other.

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"
