Well, if the buildings are only 60m apart, it probably doesn't matter  
anyway -- a direct strike to one will induce significant current into  
any non-buried cables going into the other.

But unless you've got outside antennas or other objects that are  
higher than surrounding trees, terrain, etc., a direct strike is  
pretty unlikely.

If you *do* have outside antennas, you should focus your lightning  
protection there.  Pick up a copy of the ARRL Handbook, or check one  
out from your local library -- the recommendations there are  
practical and well thought out.
