During first time visit to Banarasi, for Ritural I was surprised to see houses with Iron gate and all windows were secured with Iron. We are going on that phase. Nepalse thief do not take 100 bills, that happended to my relative.

Every one will suggest for the iron grills on widows, need some alteration then the house my look quite different than now.

From cost effectiveness why the front porch is 2"higher with space and it will be a good place for wild animal to hide ( looks so). Raliling kind of not matched is simply flat and may be used to sit and talk and children are not allowed on the 2nd foor porch.

Windows in first floor does not water shade, or needs windows that is waterproof  and wind proof.

Where is the garage? How many bathrooms you are planning to have? Where is your water tank? You do not have any guest rooms? But good for summer house or retirement house.

Looks nice but need many modification to match your need and to be protective present and future contest.
