Narayana, With openable grills with French Windows are good ! They look good and provide better sunlight/wind into the house. The by side of French Windows are internal placement of furniture becomes an issue at times. Outside sounds and weather also affect the inside a bit more.

The kitchen sink should go towards the corner next to the stove area since the plumbing would be easier due to the bathroom pipeline on that wall. The stove should be moved from there to the basin area but more central. I couldn't zoom in but what is loft above. Anyway, I think you could get rid of that wall and make it a half wall, and include a counter with 2 -3 bar chairs like for quick meals. Puja area, I think would be better elsewhere since there is non-veg food and sometimes alcohol consumption. You could have more like a partition shelf wall between dining and living, need to think more on moving the puja area somewhere else. Also, since the common bathroom is right there, you would not need another basin next to the dining area, its just not a good sight . You could mail me the floor plan and we could work on it more elaborately, but this is simply a skimmed review of the layout. Hope I was helpful .
