The house number is 101 but it's unclear which street it belongs to. Also these are combined buildings that have two independent dwellings. One of the dwellings is called 223 kingfisher but the other one closer to the corner is called 101. But it's not clear whether it is bunting or kingfisher or Grier or whatever
