text: Why so many fences and hedges on top of each other. I'm sure each boundary only has one fence or hedge. 
  I'm  pretty sure the fences and hedges don't go through the middle of houses but are terminated at the house exterior wall.
  Also it really isn't good to use linear (fence/hedge) and area (residential) tags on the same way, (this is what leads the mapper to run the fence through the buildings). 
  A better way to tag these ways is to draw and tag each feature then group them to form an area relation.
