No doors or windows in the house to let the smell escape :)

On a serious note -- kitchens need to have a door (and not be connected to dining rooms or living rooms without doors). That way smell stays in the kitchen and escape through a separate kitchen-to-street ventilation system.

Ah yes. I can't think of the last time I was in a house that had doors to the kitchen that close.
