I don't know what your data structure looks like, but you might just make a 
set of explicit assertions:

   next_to( house1, house2 )
   next_to( house2, house1 )
   next_to( house2, house3 )
   next_to( house3, house2 )
   next_to( house3, house4 )
   next_to( house4, house3 )
   next_to( house4, house5 )
   next_to( house5, house4 )

so there is no math involved.
