If zone mean same as location it is easy (I`ve never heard about zons)
You should use if/then/else tiger 6 tims for eache location. And it should looks like this:

If number of (name of building) in (name of location) equal to 1 then creat in location (name of location building if no then do nothing

In every one tiger you should use it 6 times, one for all building, and you should do 16 tigers like this, one for all location
