Dear Cecil,

Regarding to kitchen door facing main door, if relocate the kitchen or the main door is not a option, then what should I do to improve the problem?

thank you for your time and kindness.

1. May consider install a partition. Some comments on the type of partition can be found, here:-

2. On / Off! When the main door is opened, (if possible) the kitchen door is closed. Frankly this may not be practical day-to-day situation. Para 1 is a better choice.
