text: Hi, ryakr, your contribute is really appreciated but before continuing, you have to keep in mind two things. First, please connect the footways to the roads, second, the "building=*" tag should include just the building, not the building and the backyard (as here http://www.openstreetmap.org/#map=19/34.41581/-118.51876).
  
  If you need any help, feel free to have a look here
