Neighbour is building a house at the end of our smallish garden. He's doing all the work himself so tends to be evenings and weekends. He's apparently been doing it for 4 yrs but we only moved in 10 mths ago. He regularly has heavy machinery running, mini digger and a very loud, stinky dumper. He's had the engines running since about 1.30 on a lovely sunny Sunday afternoon. I've had to have the windows shut and we haven been able to go in the garden. The continual chug chug noise is doing my head in. Would I be unreasonable to ask him to stop now?
