Dear Mr. Kedarnath,
We all know that implementing vastu is not possible in every situation. So we can always implement remedies. Like in your case if you are not able to place kitchen according to vastu, here is one remedy for you:A Jupiter crystal pyramid can be stuck/paste above stove to decrease the vastu defect.
But a best solution can be given by a vastu consultant who can visit your home and analyze the onsite situation and directions.
