Looks like we won’t have to take apart the chimney after all. Although it does indeed exist on the roof as well as the second floor bedroom, it was actually taken out in the kitchen! I wont count our lucky stars because who knows what surprises await us, but for now, this is definitely in the plus column.
Another plus? this was kind of fun (smashing things up almost always is) and took just a few minutes from start to finish.
including with the photo-op and everything :)
