Only Structural alterations can help and that too after a complete analysis of the house.
I agree with post above.
If kitchen is wrongly placed.
Look into Mars Yantra (Vastu Defect Removal Yantra)
in Hindi it is called Vastu Dosh Nivarak Yantra (Vaastu Dosh Nivaran Yantra)
by pasting it at the enterance of the kitchen above the door frame.
Second thing to do is paste a Mangal Yantra (Mars Yantra) in the south-east wall of the kitchen.
Last suggestion was to have a Red Light in the kitchen during the night to generate Mars Energy in a wrongly placed kitchen.
