yes.
simple solution is a business pack, covering building, and property owners liability.
fire rate around 20%'ish, simple property owners liab for an office say $500'ish.
therefore 500,000 building sum insured =$1000, + liab $500
= $1500 +gst+stamp.
ballpark only obviously.
might want to include glass, business interruption (loss of rent), machinery breakdown, various other options as well.
