First of all the images you posted you cant make anything out what you got there. Secondly you should contact a local Architect when doing something like this, not only for structural reasons, but window design as well. He will layout window detail based on the window sizes available from a certain manufacturer or you can take his drawings which indicate opening detail to a place who sells windows, and they have catalogs of window combinations and sizes to make it work with what you have.

I had purchased hafele hob 10 months back... I got it serviced 6 times... Now i requested for replacement with new one... Still they have not attended my request...

first of all, Thank you guys for those valuable inputs. yes, as far as cleaning goes, its just been finished installing and I have asked them to clean them up. And also, I observed that the frosting on the glass didn't look that good, so I am going for the filming on certain portions of the doors n windows. - Is there a particular quality of films that I may choose for this ? - Yes, lighting is definitely the criteria I had in mind which can bring up the finish to this. And i am worried about this , as I did not go for False Roofing, bcos the ceiling is already at a low height. I should really refine my ideas on the lighting part. - the stairs are floored with white Marble stone..My mom loves it and the matting on it might hinder its beauty, but yes I will surely consider that as well. Thank you again.

Please provide the total dimension of the room along with the window and door positions. You must inform if she has any particular requirement so it'll be easier to plan it .
