Hi there!
Apologies for the late reply. I will be releasing an update which will expand this pack even further and bring new building types along with many other.
Its funny because someone just asked almost the same question as you did in the product page just yesterday:
Thank you for your compliments and for your support!
Let me know if you have any other questions. (I will be more quick this time 
)
Kind Regards,
-KGY
