Destroying Farmer's House.

I apologise if this has been asked before, but I couldn't find it on the forums for this type of house.
Basically, I want to destroy my Farmer's House so that I can build a townhouse in its place. The Wiki lists its soak value as unknown. My phlegm is 36 and I can't overcome the soak value. Can anyone give me an indication of how much more phlegm I need? >~<
Thanks.
