Hello, I have been in my new build flat for a year now and have been complaining to my developers about my neighbour's cooking smells coming through my ensuite and my bathroom. After months of back and forth, they sent someone in to check that the extractor fans was connected to outside of the building and whether there were any leaks in the flooring. Nothing 'wrong' was found and I was dismissed as they said it was not a structural issue. I contacted the NHBC and explained everything to them but they also said to me that there was nothing they can do if it is not a structural issue. I'm unsure of what to do at this point. Does anyone know what the reason may be for my neighbour's cooking smells coming through my ensuite and my bathroom? Or, better yet, any possible solutions for this? It would be greatly appreciated Thanks, Izz
