In this base, I have 3 sard barracks and 3 fremen tents along with a hangar and 3 refineries.  A very nice looking base.  If I want a starport, there is plenty of room.  The only thing I always keep in mind is not to block the path my vehicles take out of the factory.  

Now, for the challenge:  try to figure out what mistake I made.  This is a very good base, but when you play against guild, there is always one rule of thumb you should always try to do.  I didn't do it here because I wanted to better illustrate to you why its such a good rule of thumb.  What you are looking for is a strategic vulnerability.  Can you tell what it is?  I'll give you the answer later.
