Does anyone know where this sound is coming from? It sounds like two chainsaws but could be something else. It started at about 8am this morning (Sunday) and was happening yesterday as well. It?s so loud for a Sunday morning - surely people aren?t allowed to do that. I would just like to understand what it is and where it is coming from. For reference I am at the peckham rye end of Barry Road.
