ah wait no, I think I know where you are talking about. Nah I built mine from scratch. Just across are some places that are similar to how mine used to be. I can see a cobble tower from my cobble tower. I did at some point accidently mine into another mine building an underground farm. but I blocked that off.
If yours has a bookcase on the staircase next to the door, then you happen to be that neighbor. :V
My area has no beds, I haven't been blessed with sheep of suicidal tendancies to get any. And the spiders I've killed were all carrying nothing.
Also my tower kind of looks like its got faces on all sides, and the entrance is suspended in the air with a thin staircase up. You'll know it when you see it, the achetechture isn't square as i've used staircase and slab blocks to make it so it wouldn't be entirely.
I agree with the cartograph notion, I want to go outside and screenie this place, but my home computer lags too much. all I've managed to do is get some signs up, and I dare not try and walk past the entrance (which is instead blocked with gravel) as I don't fancy an exploding penis coming after me.
