The main door to your house is the principle entry of chi entering your living space so it usually commands the attention of many feng shui masters. It is not good to have kitchen facing the main door and extremely bad if you can see your stove from the main door. When I said facing I meant the door and kitchen door must be aligned in a straigt line. However, for open concept kitchen, as long as the main door is not directly facing the stove, it is alright.
Kitchen belong to fire element. When qi rushing into the kitchen, it will brings complication to your health involving heart, eyes, skin, blood circulation.
If you can't avoid this confrontation, putt a tall plant with big leaves between the door and kitchen.
