BFP Huge File Size

Question

Hey, I'm having an issue with a BFP file size. The file is clocking in at over 11MB. The building isn't huge, and bigger buildings are only about 1.5MB. I've compressed, I've cleaned up, I've manually deleted everything out of the file I can - no references or unused cells, layers, text or dimension styles. I'm at a loss on how to cut this file down in size. 
 
 Could it be the fact that there's an extensive design history attached to the file? Can I delete the design history without affecting the database connections? 
 
 Any suggestions?

 Thanks for letting me know, could you please check by deleting a few minor design history options and see whether it is impacting the file size? I wouldnt recommend for deleting the entire not knowing their impact. 
 
 Please let me know the results.
