Congrats on your find. They are very nice structures (all the Steck houses).
However, I cannot congratulate you on your choice of use. Historically, that would never have been allowed in any Medieval town. While not saying such activity was not unheard of, the historical fact is that it really was unheard of! Unlike today, at that time it would have been a thing of rumours that such places ever did or would exist and it would be on par with the "boogieman" for fact of existence.
