  To get you started, I've added the outlines of the buildings in that area, as best as we can tell from satellite view..
  
  Now, I'm wondering if your entrance is exclusively for no 1 or if it is a shared entrance -- in which case the tag should be something like addr:housenumber 1-4 and an extra tag is needed addr:interpolation = all (or odd or even, as appropriate).
  
  Ideally, numbers should be shown for the whole estate. That might help if people see higher numbers at the other end to look along the block for the lower numbers.
