well the '70s blocks in Poland do have quite some shared greenery, at least the southern part were I've been extensively, but I saw them also up north, even in the outskirts of 'special case' cities that have had their historical centers preserved or restored like Gdansk [1] or Torun [2] - that's what planner can do to encourages a local and social aspect to the local neighbors
but still it doesn't solve working places interconnection in a way that makes walking nor public transit satisfactory.
