need yalls advice with kennels

[tuffcutt]

i am fixing to build kennel and this is kind of what i was thinking...

open the door on the front and a room on the left (feed and tack) and a room on the right (beer cave/ i mean man cave  ) with an alley in between then past them it open up to the pens with an alley going between them, 6 pens on each side. what i was needing help with is what size should each run/pen be, or what yall would or wouldnt do different, anyone had pics of theirs. i would appreciate it anyhelp kinda just tossing arounds some ideas...

 sounds like a nice set up.I would go with 5x10 runs plenty room for 1 dog and could double up if need be.I have 5x10 above ground kennels with barrels mounted outside and  a 12x16 ft building for feed,equipment,and the much loved coffee pot.I also have a 5x6 ft whelping pen inside.
