I need help detecting when a structure is built

I want my mod to detect whether a structure has been placed or not in order to summon a block. I want this to function like an iron golem but the blocks will be placed further away from each other like the diagram below. Sorry if my diagram or explanation does not make sense as I am new to modding. The structure will be 3x3 btw.

 I = Modded Block                                                        

  I - I    
  I - I        
     

 - = Empty Space
