About 2 years ago we had new neighbours move in to the house next door. We now experience strong cooking smells on our landing and in ds's bedroom even though his room adjoins a bedroom. Assuming they cook in the kitchen, which is on the far side of their house and doesn't adjoin our kitchen wall, is it possible for the smells to travel up and over so to speak. Or are they possibly cooking in the bedroom. Even now the smell of cooking is wafting.
